Abstract
Background Atrophic scarring is a severe form-disfiguring sequela of acne, which can lead to negative effect on patients' life. Fractional microplasma radiofrequency (RF) has emerged as a promising modality, leveraging dermal fibroblast remodeling to enhance aesthetic results for scars and hyperpigmentation. This study evaluates the efficacy and safety of high-power fractional microplasma RF for atrophic acne scars, considering patient tolerance to procedural discomfort. Methods In this prospective study, 95 Chinese patients with atrophic facial acne scars underwent three sessions of fractional microplasma RF treatment, with assessments at 1, 3, and 6 months post-treatment. Patients were categorized based on treatment power: Group A (50-70 W) and Group B (70-85 W). Efficacy was determined by three independent dermatologists using digital photographs and Echelle d'Evaluation Clinique des Cicatrices d'Acné (ECCA) scores, and patient-reported outcomes gauged satisfaction levels. Results Eighty-six patients completed the study. Significant improvements were observed, with a reduction in ECCA scores from 107.21 to 42.27 (P<0.05), demonstrating notable scar amelioration across both groups, albeit with a superior outcome in Group B. All patients experienced transient side effects such as pain, erythema, and edema, deemed tolerable with no long-term adverse effects reported. The treatment was well-received, with high satisfaction rates, underscoring its efficacy and acceptable safety profile. Conclusion Fractional microplasma RF therapy, particularly at higher power settings, is an effective and safe option for treating atrophic acne scars, offering significant aesthetic improvement with manageable discomfort. This modality presents a valuable addition to acne scar management strategies, especially for patients with darker skin tones seeking minimal downtime and reduced risk of hyperpigmentation.

[PMID: 38532647 DOI: 10.1111/jocd.16298] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2023] [Revised: 03/12/2024] [Accepted: 03/14/2024] [Indexed: 03/28/2024]
Abstract
BACKGROUND Microplasma fractional radiofrequency (MP FRF) technology has been increasingly used for acne scars. Nevertheless, little evidence has analyzed the factors influencing its effectiveness before and during treatment. AIMS To evaluate the clinical factors affecting the effectiveness of MP FRF therapy for atrophic acne scars. METHODS We analyzed retrospectively the clinical data of 79 acne scar patients treated with MP FRF technology. The outcome of interest included the effectiveness and adverse events after MP FRF treatment. Multivariable logistic regression was utilized to evaluate clinical factors associated with effectiveness after the initial session. RESULTS All patients received 115 sessions of MP FRF therapy (average: 1.5 sessions). Twenty-eight (35.4%) patients improved moderately to excellently after one session. We found that the severe grade before treatment was negatively correlated with the effectiveness according to Goodman-Baron qualitative scores (OR = 0.02, 95% CI [0.001, 0.37], p = 0.009). The presence of icepick scars was also a negative correlation factor for the effectiveness (OR = 0.06, 95% CI [0.004, 1.00], p = 0.049). Furthermore, after excluding the effects of icepick scars and Goodman-Baron scores before treatment, ECCA scores were also correlated with effectiveness (OR = 1.04, 95% CI [1.01, 1.06], p = 0.009). CONCLUSION MP FRF therapy was effective in treating atrophic acne scars with no permanent adverse events. The severity of Goodman-Baron qualitative scores and icepick scars were independent clinical factors affecting effectiveness, suggesting the possible requirement for additional treatments other than MP FRF for severe acne scars and icepick scars.

Comparison of the fractionated Nd: YAG 1064-nm picosecond laser with holographic optics and the fractional CO 2 laser in atrophic acne scar treatment: a prospective, randomized, split-face study. Int J Dermatol 2024. [PMID: 38924534 DOI: 10.1111/ijd.17296] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 05/09/2024] [Accepted: 05/20/2024] [Indexed: 06/28/2024]
Abstract
KEY POINT The 1064-nm picosecond laser with holographic optics demonstrated significant efficacy in treating atrophic acne scars. BACKGROUND Picosecond lasers with fractionated optics have enabled the development of a breakthrough skin rejuvenation method. The authors compared the fractionated, non-ablative neodymium-doped yttrium aluminum garnet 1064-nm picosecond laser with holographic optics and the fractional CO2 laser in treating atrophic acne scars. METHODS One side of each patient's face was randomly allocated and treated with three sessions of the 1064-nm picosecond laser with holographic optics at 2-month intervals. In contrast, the other side was treated with the fractional CO2 laser. Participants were followed up 3 months after the final session. The primary outcome included the physicians' evaluation using the ECCA grading scale and a four-point scale to assess improvement. The patients' assessment of progress, their overall satisfaction and preferences, and the side effects were also evaluated. RESULTS No significant difference was observed between the two lasers in terms of the mean ECCA scores after treatments (P = 0.209). The physicians' improvement assessment was more significant for the fractional CO2 laser (P = 0.001). The patients' evaluation of improvement and subjective satisfaction were consistent with physicians' four-point scale results. The picosecond laser side had fewer adverse effects (P < 0.001). CONCLUSION The fractionated, non-ablative Nd: YAG 1064-nm picosecond laser with holographic optics and the fractional CO2 laser were effective and safe in treating atrophic acne scars. Significantly better clinical outcomes were observed with the fractional CO2 laser, whereas fewer adverse effects were noted with the 1064-nm picosecond laser with holographic optics.

Abstract
Acne scarring is a frequent complication of acne. Scars negatively impact psychosocial and physical well-being. Optimal treatments significantly improve the appearance, quality of life, and self-esteem of people with scarring. A wide range of interventions have been proposed for acne scars. This narrative review aimed to focus on facial atrophic scarring interventions. The management of acne scarring includes various types of resurfacing (chemical peels, lasers, and dermabrasion); the use of injectable fillers; and surgical methods, such as needling, punch excision, punch elevation, or subcision. Since the scarred tissue has impaired regeneration abilities, the future implementation of stem or progenitor regenerative medical techniques is likely to add considerable value. There are limited randomized controlled trials that aimed to determine which treatment options should be considered the gold standard. Combining interventions would likely produce more benefit compared to the implementation of a single method.

Abstract
BACKGROUND Although different options are available for treating post-traumatic facial scars, they remain a therapeutic challenge. AIM To evaluate the safety and effectiveness of combined therapy using micro-plasma radiofrequency (MPRF) technology and silicone gel (SG) dressings for treating post-traumatic facial scars. METHODS This retrospective study was conducted at a single center. Patients with facial injuries in the outpatient and emergency units of the Department of Plastic Surgery at our hospital underwent debridement and cosmetic sutures performed by the same surgeon from October 2020 to October 2021. In the first arm, patients with facial injuries were treated with MPRF technology and SG, and in the second arm, they were treated with SG dressings alone. We observed the safety and effectiveness of these treatments in both arms. RESULTS A total of 32 patients with facial injuries were treated with MPRF technology and SG dressings (combined treatment group), and 28 patients were treated with SG dressings alone (SG group). After 6 months of treatment, the Vancouver Scar Scale scores of the combined treatment and SG groups were 1.38 ± 0.71 and 4.39 ± 0.50, respectively, and the difference was statistically significant (P < 0.01). After 6 months of treatment, the effectiveness rate in the combined treatment group was 93.8%, which was significantly higher than that in the SG group (67.9%), and the difference between the two groups was statistically significant (P < 0.05). No obvious adverse reactions occurred in the two arms. CONCLUSION Treating early post-traumatic facial scars with combined MPRF technology and SG is significantly better than treating them with SG alone; moreover, the combined therapy is safe and effective.

Abstract
Background: Acne vulgaris is an inflammatory disease of the pilosebaceous unit in teenagers. Acne-induced inflammation leads to acne scarring. Scholars have discussed acne scar treatments; however, energy-based devices with satisfactory outcomes remain unidentified. Objective: To measure quartile grading scale and visual analog scale (VAS) to study the difference between energy-based devices. Methods: We included randomized controlled trials that evaluated patients with acne scars. The primary outcomes were the quartile grading scale and VAS scores. We used Confidence in Network Meta-Analysis to evaluate indirectness, imprecision, heterogeneity, and incoherence. Results: A total of 26 studies met the inclusion criteria. The quartile grading scale results revealed that ablative fractional laser was significantly more effective than nonablative fractional laser (standard mean difference [SMD]: 0.516, confidence interval [95% CI]: 0.281-0.750) and radiofrequency treatment (SMD: 0.941, 95% CI: 0.540-1.342). Moreover, nonablative fractional laser was significantly more effective than radiofrequency treatment (SMD: 0.426, 95% CI: 0.049-0.802). No significant difference in VAS score was found among the devices. Conclusion: Ablative fractional laser is an effective treatment for acne scars although it is associated with more pain.

In vivo electrochemical lipolysis of fat in a Yucatan pig model: A proof of concept study. Lasers Surg Med 2023; 55:135-145. [PMID: 36511512 DOI: 10.1002/lsm.23620] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Revised: 11/01/2022] [Accepted: 11/26/2022] [Indexed: 12/15/2022]
Abstract
OBJECTIVES Traditional fat contouring is now regularly performed using numerous office- based less invasive techniques. However, some limitations of these minimally invasive techniques include high cost or limited selectivity with performing localized contouring and reduction of fat. These shortcomings may potentially be addressed by electrochemical lipolysis (ECLL), a novel approach that involves the insertion of electrodes into tissue followed by application of a direct current (DC) electrical potential. This results in the hydrolysis of tissue water creating active species that lead to fat necrosis and apoptosis. ECLL can be accomplished using a simple voltage-driven system (V-ECLL) or a potential-driven feedback cell (P-ECLL) both leading to water electrolysis and the creation of acid and base in situ. The aim of this study is to determine the long-lasting effects of targeted ECLL in a Yucatan pig model. METHODS A 5-year-old Yucatan pig was treated with both V-ECLL and P-ECLL in the subcutaneous fat layer using 80:20 platinum:iridium needle electrodes along an 8 cm length. Dosimetry parameters included 5 V V-ECLL for 5, 10, and 20 minutes, and -1.5 V P-ECLL, -2.5 V P-ECLL, -3.5 V P-ECLL for 5 minutes. The pig was assessed for changes in fat reduction over 3 months with digital photography and ultrasound. After euthanasia, tissue sections were harvested and gross pathology and histology were examined. RESULTS V-ECLL and P-ECLL treatments led to visible fat reduction (12.1%-27.7% and 9.4%-40.8%, respectively) and contour changes across several parameters. An increased reduction of the superficial fat layer occurred with increased dosimetry parameters with an average charge transfer of 12.5, 24.3, and 47.5 C transferred for 5 V V-ECLL for 5, 10, and 20 minutes, respectively, and 2.0, 11.5, and 24.0 C for -1.5 V P-ECLL, -2.5 V P-ECLL, -3.5 V P-ECLL for 5 minutes, respectively. These dose-dependent changes were also evidenced by digital photography, gross pathology, ultrasound imaging, and histology. CONCLUSIONS ECLL results in selective damage and long-lasting changes to the adipose layer in vivo. These changes are dose-dependent, thus allowing for more precise contouring of target areas. P-ECLL has greater efficiency and control of total charge transfer compared to V-ECLL, suggesting that a low-voltage potentiostat treatment can result in fat apoptosis equivalent to a high-voltage DC system.

Abstract
Different treatment options for post-acne scars exist, but with varying clinical efficacy, side effects, and prolonged downtime. This study aims to compare the efficacy and safety of combined subcision with either fractional CO2 laser or cross-linked hyaluronic acid filler (HA) versus subcision alone in the treatment of facial atrophic post-acne scars. Forty patients with atrophic post-acne scars were subjected to subcision on both sides of the face, then were randomly divided into three groups. Group I (20 patients): subcision combined with cross-linked HA filler injection at one side of the face; group II (20 patients): subcision followed by fractional CO2 at the other side of the face; and group III (20 patients): with subcision only as a control group. Treatment sessions were every month until clinical improvement or for maximum three sessions. The treatment's efficacy was assessed by Goodman and Baron's qualitative and quantitative grading systems. The two blinded investigator scores showed significant improvement in both the filler side versus subcision (p value = 0.015), and the fractional laser side versus subcision (p value < 0.001), with no statistically significant difference between both sides (p value = 0.171). Qualitative grading by Goodman and Baron scores showed that the percentage of patients with excellent improvement was higher in group 1 and group 2 than in group 3 with p value = 0.031; also the mean percentage of reduction in quantitative grading was higher in group 1 and group 2 than in group 3 with p value < 0.00. Either combined subcision with fractional CO2 laser or with cross-linked HA filler achieved superior improvement in facial atrophic post acne scars treatment with no serious side effects in this study. However, subcision only by blunt canula also had modest improvement.

Abstract
BACKGROUND Fractional radiofrequency (FRF) is increasingly used for acne scars. The common coexistence of acne scars and active acne is a challenge in the timely management of acne scarring. AIMS We conducted a systematic review and meta-analysis to compare the efficacy and safety of FRF treatment with the lasers for acne and/or acne scars. METHODS A systematic search was performed on PubMed, Embase, Ovid, Cochrane Library, and Web of Science. Compared with the lasers, a meta-analysis was conducted to assess the clinical improvement and adverse events after FRF treatment. RESULTS Eight randomized controlled trials were included. FRF group was more effective than the laser group in patient-evaluated acne improvement (RR = 1.35, 95% CI: 1.01 ∼ 1.80). Regardless of observer assessment or patient evaluation, the FRF group was as effective as the laser group in treating atrophic acne scars (RR = 0.92, 95% CI: 0.78 ∼ 1.08; RR =1.15, 95% CI: 0.99 ∼ 1.34). Although there was no difference in pain level and crusting time between the two groups (SMD =0.20, 95% CI: -0.72 ∼ 1.12; SMD = -0.93, 95% CI: -2.38 ∼ 0.52), PIH incidence of FRF was significantly lower than that of the laser group (RR = 0.12, 95% CI: 0.04 ∼ 0.35). The duration of erythema after FRF treatment was also obviously shorter than that after the laser treatment (SMD = -0.78, 95% CI: -1.37 ∼ -0.18). Subgroup analysis showed that at least a 12-week follow-up was required to observe the full effects of FRF. CONCLUSIONS FRF could be a better choice for atrophic acne scar patients with active acne. FRF is superior in treating atrophic acne scar patients prone to pigmentation.

Abstract
BACKGROUND AND OBJECTIVE New and improved treatment modalities, including lasers and energy-based devices, are promising treatment options for hypertrophic scars. This study aimed to assess the efficacy and safety of fractional microneedle radiofrequency (FMR) compared with fractional carbon dioxide (CO2 ) laser in the treatment of postburn hypertrophic scars. PATIENTS AND METHODS Twenty patients with hypertrophic scars were enrolled in the study. Two areas in each patient were randomly assigned to fractional CO2 laser or FMR. Four sessions, 6-8 weeks apart were performed. The Patient and Observer Scar Assessment Scale (POSAS) was used for clinical evaluation, H & E and orcein-stained samples were examined for histopathological assessment, and tissue transforming growth factor beta 1 (TGFβ1 ) levels were measured for biochemical evaluation. RESULTS Both fractional CO2 and FMR-treated areas showed significant improvement in all parameters 1 month after treatment. Fractional CO2-treated areas showed a higher degree of improvement compared with FMR in OSAS (p = 0.025), elastin grading (p = 0.004), and TGFβ1 levels (p = 0.000). Patients reported less downtime and showed less postinflammatory hyperpigmentation with FMR compared with fractional CO2, but this did not reach statistical significance (p = 0.327, p = 0.231; respectively). CONCLUSION Our results demonstrate the value of FMR as an effective alternative to fractional CO2 in the treatment of hypertrophic scars, with a potentially favorable safety profile.

Chilicka K, Rusztowicz M, Szyguła R, Nowicka D. Methods for the Improvement of Acne Scars Used in Dermatology and Cosmetology: A Review. J Clin Med 2022; 11:jcm11102744. [PMID: 35628870 PMCID: PMC9147527 DOI: 10.3390/jcm11102744] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 05/10/2022] [Accepted: 05/11/2022] [Indexed: 02/07/2023] Open
Abstract
Acne vulgaris is a chronic skin disease that, depending on its course, is characterized by the occurrence of various skin eruptions such as open and closed comedones, pustules, papules, and cysts. Incorrectly selected treatment or the presence of severe acne vulgaris can lead to the formation of atrophic scars. In this review, we summarize current knowledge on acne scars and methods for their improvement. There are three types of atrophic scars: icepick, rolling, and boxcar. They are of different depths and widths and have different cross-sections. Scars can combine to form clusters. If acne scars are located on the face, they can reduce the patient’s quality of life, leading to isolation and depression. There are multiple effective modalities to treat acne scars. Ablative lasers, radiofrequency, micro-needling, and pilings with trichloroacetic acid have very good treatment results. Contemporary dermatology and cosmetology use treatments that cause minimal side effects, so the patient can return to daily functioning shortly after treatment. Proper dermatological treatment and skincare, as well as the rapid implementation of cosmetological treatments, will certainly achieve satisfactory results in reducing atrophic scars.

Abstract
Fractional laser (FL) resurfacing has proved its effectiveness in acne scars treatments. To evaluate the efficacy of Fractional laser systems for treatment of acne scars as a monotherapy, and as adjunctive therapy with other treatment types. A systematic literature review was performed by searching the electronic databases PubMed, Google Scholar, and Embase. Fractional laser has proven therapeutic efficacy of over 26% in treating acne scars, with minor and transient side effects, and well-tolerant pain. The application of PRP not only accelerated recovery and reduced adverse events, but also enhanced localized collagen neogenesis and redistribution. The addition of surgical treatments to Fractional Laser Systemes (FLS) therapy delivers the best treatment results for Icepick scars. Fractional laser is an effective tool for treating acne scars. The degree of effectiveness varies according to the laser parameters, the number of treatment sessions, skin photo type, the severity and the type of scars. The application of Platelet-Rich Plasma (PRP) and Fractional Radiofrequency Microneedle (FRM) in addition to the FL treatment improves the therapeutic efficacy and reduces the appearance of Post Inflammatory Hyper-Pigmentation (PIH), and is the ideal treatment for dark-skinned patients. FL therapy along with surgical methods such as subsicion and punch techniques provided the best improvements for deep scars.

Abstract
OBJECTIVES Skin rejuvenation with radiofrequency has been a widely used treatment modality for the safe and efficient remodeling of the dermis and revision of textural irregularities, achieved with minimal downtime. The efficacy of fractional radiofrequency (FRF) specifically for acne scarring has not been widely established. The objective of this clinical trial was to establish the efficacy and safety of FRF for moderate to severe acne scarring in a wide range of Fitzpatrick skin types using two different applicator tips to deliver energy to the skin (80-pin of up to 124 mJ/pin and 160-pin of up to 62 mJ/pin). METHODS Enrolled subjects received a series of three FRF treatments to the full face, each 4 weeks apart. A visual analog scale was utilized to assess pain of the treatment. Subject satisfaction questionnaires were completed at follow-up visits at 6 and 12 weeks post final treatment. Photographs were graded for change by three blinded evaluators using the Global Aesthetic Improvement Scale (GAIS). RESULTS Image sets of 23 enrolled subjects were assessed by blinded evaluation, showing a statistically significant improvement (p = 0.009) from the baseline visit to the 12-week follow-up on the GAIS for acne scarring. Subject satisfaction was high with subjects giving an average satisfaction score of 3.27 ("satisfied") out of 4. Pain was "mild" as treatments were rated an average of 2.15 on a 10-point visual analog scale. The GAIS score of the 80-pin tip improved patients' acne scars treated with that applicator by 1.06 points and 0.85 for the 160-pin tip. Ninety-five percent (95.5%) of subjects reported either a mild, moderate, or significant improvement to their treatment area. Ninety-one percent of subjects reported that they would recommend the treatment to a friend. CONCLUSION FRF produced a statistically significant improvement in acne scarring when assessed by independent blinded evaluators. No serious adverse events resulted from treatment by either applicator tip. Treatment pain was low and tolerable among subjects of all Fitzpatrick skin types. Subjects had high levels of satisfaction with the results.

Abstract
Background: Acne scar is a distressing psychosocial problem, and it has a negative effect on the quality of life. Although variety of approaches are available, demand of less invasive and more effective ways for their treatment is needed. Objective: This study aimed to assess and compare the clinical safety, efficacy, and tolerability of fractional carbon dioxide (FCO2) laser versus fractional microneedling radio frequency (MNRF) in the management of acne scars. Materials and Methods: This study was a prospective, observational, nonrandomized, open-labeled study of total 50 patients selected according to Goodman and Baron global qualitative acne scar grading, and they were divided into two groups of 25 each, having Fitzpatrick skin type III–V. A total of four sessions were given for both the groups at an interval of 2 months. The assessment was done by the treating physician as well as by the blinded physician. Both the subjective and the objective assessment was done at the last follow up given at second month of the fourth session. Results: The mean score of 25 patients in each group of FCO2 and fractional MNRF, decreased from 29.24 to 10.7 (i.e., 63.41%) and from 33.24 to 13.04 (i.e., 60.72%), respectively, as calculated by Goodman and Baron quantitative grading assessed by the treating physician (P = 0.0001). Grade 4 (>75%) improvement was shown by four patients and Grade 3 improvement (51%–75%) was shown by 14 patients among FCO2 group, and similarly Grade 4 (>75%) improvement was shown by three patients and Grade 3 improvement (51%–75%) was shown by 12 patients among MNRF group, as observed by a blinded physician (P = 0.689). Conclusion: Both modalities are equally effective in the treatment of acne scars; however, fractional MNRF having lesser down time and Post inflammatory hyperpigmentation (PIH) among darker skin shades, with good patient satisfaction score, makes it an efficient and safer treatment option as compared to FCO2.

Abstract
BACKGROUND Radiofrequency (RF) is a non-invasive or minimally invasive procedure with a low risk of complications. It has been employed for several aesthetic purposes. AIM This study aimed to conduct a systematic literature review on the use of RF for aesthetic applications and assess the level of accumulated evidence for each condition. METHODS Using the MEDLINE/PubMed and EMBASE databases, we searched for articles published from 2009 to 2019 describing the use of RF treatment for aesthetic purposes. RESULTS Our search approach identified 25 randomized clinical trials investigating the efficacy of RF in the following clinical situations: body contour improvement, facial rejuvenation, acne scar treatment, alopecia, and rosacea. There were problems with the quality of the studies, especially regarding selection, performance, and detection bias. CONCLUSION Our study revealed that RF treatment is potentially promising in all of the evaluated clinical situations; however, we were not able to identify a level of evidence that justifies its use over other therapeutic options currently available on the market.

Abstract
BACKGROUND AND OBJECTIVE Both fractional micro-plasma radiofrequency (RF) and fractional microneedle RF are novel devices that can be applied for the treatment of atrophic acne scars, and they have both been proved to be effective. To compare the clinical effectiveness and adverse reactions of fractional micro-plasma RF and fractional microneedle RF for the therapy of facial atrophic acne scars in a randomized split-face study. STUDY DESIGN/MATERIALS AND METHODS Sixty patients with facial atrophic acne scars received three applications at 2-month intervals in a randomized split-face study using fractional micro-plasma RF and fractional microneedle RF on different sides of the face. Three independent dermatologists evaluated the improvement in acne scars using the ECCA grading scale (Echelle d'Evaluation Clinique des Cicatrices d'Acné) by comparing the digital images and graded the improvement in the acne scars. Patients were asked to provide a self-evaluation of satisfaction for efficacy and safety. Adverse effects were also recorded after each treatment. RESULTS In total sixty patients completed the entire study. A significant improvement was observed in the appearance of acne scars, and the mean ECCA scores improved significantly after both modalities. The mean decrease in ECCA scores from the baseline was significantly more pronounced in fractional micro-plasma RF as compared with fractional microneedle RF (41.33 ± 20.19 vs 32.17 ± 17.35; P < 0.05). The degree of clinical improvement was also significantly better for fractional micro-plasma RF. Pain, erythema, and swelling were observed in all patients after both treatments. The pain was more intense during micro-plasma RF treatment (P = 0.000), and the duration of pain and erythema were longer than with fractional microneedle RF (P = 0.000). Postinflammatory hyperpigmentation (PIH) was observed in one patient on the fractional micro-plasma RF side while no PIH was observed on the fractional microneedle RF side. No infections or worsening of scarring was observed with either treatment. No subject was dissatisfied with the efficacy of either device. Rolling scars tended to respond better to fractional micro-plasma RF treatment compared with fractional microneedle RF (P = 0.000). CONCLUSIONS Both fractional micro-plasma RF and fractional microneedle RF are effective and safe methods for improving atrophic acne scars. Fractional micro-plasma RF is significantly more effective for atrophic acne scars, especially for rolling scars. However, fractional microneedle RF has fewer side effects plus shorter downtime, and patients are more comfortable after the treatment. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

Abstract
BACKGROUND AND OBJECTIVES Recently, picosecond laser treatment has been used as an effective treatment for acne scars. To evaluate the efficacy and safety of a picosecond alexandrite laser with a diffractive lens array in the treatment of acne scars in Chinese patients. STUDY DESIGN/MATERIALS AND METHODS Patients with facial acne scars were treated with a picosecond alexandrite laser in three sessions at 4- to 6-week intervals and followed up for 2 months. Primary outcomes were measured by physicians' blinded evaluation of the acne scar using the ECCA (échelle d'éva physicians'luation clinique des cicatrices d'acné) grading scale. The secondary outcomes included the investigator global assessment (IGA) on the improvement of post-inflammatory erythema (PIE), patients' assessment of improvement on a 4-point scale and of satisfaction on a 5-point scale. Pain scores and adverse effects were also evaluated. RESULT Twenty patients with Fitzpatrick skin types III and IV were enrolled in the study and completed all treatment and follow-up visits. The mean ECCA scores fell from 197.75 ± 35.26 to 142.00 ± 35.92 (a 28% improvement), and the change was significant (P = 0.000). The mean IGA score of PIE improvement was 3.03 ± 0.75 (0 = no improvement and 4 = 76-100% improvement). On the basis of the patients' self-assessment, the average improvement scores were 2.30 ± 0.98 (0 indicating 0-25% improvement and 3 indicating >75% improvement). In total, 50% and 30% of the patients were "satisfied" and "very satisfied," respectively, with the treatment. The mean pain score was 3.20 ± 0.50 (0 = no pain, 10 = maximum pain) with topical anesthesia. The adverse effects included transient and mild erythema, edema, and scabbing. CONCLUSIONS Treatment with a picosecond alexandrite laser with a diffractive lens array is effective and safe for acne scars in Chinese patients. Lasers Surg. Med. © 2019 Wiley Periodicals, Inc.

Abstract
Background: It is anticipated that the combined treatments of ablative laser and human stem cell-conditioned media produce the synergistic effects.Objectives: To investigated the effects of human stem cell-conditioned media (HSCM) as a post-procedural agent after fractional CO2 laser procedure in patients with atrophic acne scars and skin pores. Method: Both cheeks of 15 subjects were treated with a fractional CO2 laser. HSCM was randomly applied to one of the resurfacing sites (T) and normal saline was applied to the other site as a control (C). During the next six days, a solution containing 80% HSCM and hyaluronic acid (HA) was applied on the treated side (T) and HA alone was applied to the control side (C). Scar volume and erythema were objectively evaluated using an Antera 3D® CS. Result: After two months, the scar volume was reduced by 23.5% (T) versus 15.0% (C) (p = .143) and the volume of the skin pores was reduced by 37.6% (T) versus 15.9% (C) (p = .006), while the erythema was increased by 2.8% (T) versus 3.1% (C) (p = .934). Atrophic scar and the skin pores in the HSCM-applied area improved by at least 15.0% after a single treatment session, suggesting better results compared with the control side.Conclusion: HSCM may augment the regenerative effects of fractional CO2 laser.

Abstract
BACKGROUND Acne scars lead to social and psychological problems for patients, and they should be treated effectively. Ablative and nonablative lasers have been used for the treatment of acne scars in recent years. AIMS The aim of this study was to evaluate the effectivity of combined FCL and FmRF treatment for acne scars retrospectively. METHODS A total of 72 patients with acne scars who received FCL + FmRF treatment between 2014 and 2016 were included in this study. Photographs of patients before treatment and 1 month following the last treatment session were scored by two blinded researchers, according to the ECCA acne scar scoring method. Patients were contacted via telephone after 1 month following the last treatment and asked to evaluate their satisfaction with the treatment outcome using a 5-point Likert-type scale. RESULTS A significant decrease was noted in ECCA scores after the treatment along with temporary side effects. Change from pretreatment scores was significantly higher in patients very satisfied vs satisfied with treatment. The number of treatment sessions was positively correlated with treatment-related change in ECCA scores. CONCLUSIONS In conclusion, our findings revealed association of FCL + FmRF treatment with significantly improved ECCA scores, mild pain experience, and low rate of side effects in patients with acne scars, despite usage of high-energy FLC dose and five sessions of treatment on average. More remarkable improvement in ECCA scores during treatment seems to be associated with higher patient satisfaction and to be more likely in patients with darker skin types.

Abstract
BACKGROUND Modalities for atrophic acne scarring can be classified depending upon the needs they satisfy; that is, resurfacing, lifting/volumization, tightening, or surgical removal/movement of tissue that is required for correction. A plethora of treatment options have resulted from the need to treat various acne scar types, variability of responses noted in various skin types, and increasing popularity of minimally invasive modalities. Still, there is a lack of consensus guidelines on treatment or combination therapies for various clinical scenarios. OBJECTIVE This systematic review includes a critical evaluation of the evidence relevant to these modalities and various multimodality therapies. METHODS We performed a systematic literature search in Medline and EMBASE databases for studies on acne scar management. Also, we checked the reference lists of included studies and review articles for further studies. A total of 89 studies were included in our quality of evidence evaluation. RESULTS The efficacy of lasers and radiofrequency in atrophic acne scarring is confirmed by many comparative and observational studies. Other modalities can be used as an adjunct, the choice of which depends on the type, severity, and number of atrophic scars. Minimally invasive procedures, such as fractional radiofrequency and needling, provide good outcomes with negligible risks in patients with dark or sensitive skin types. CONCLUSIONS There is a lack of high-quality data. Fractional lasers and radiofrequency offer significant improvement in most types of atrophic acne scars with minimal risks and can be combined with all other treatment options. Combination therapies typically provide superior outcomes than solo treatments.

Abstract
BACKGROUND Acne scarring is a common disfiguring sequela of acne vulgaris which can lead to serious psychosocial problems and have a negative effect on patients' quality of life. Although a variety of approaches can be used to treat atrophic acne scars, disadvantages such as long-healing time, dyspigmentation, infections, and prolonged erythema make these treatments unsatisfactory especially for Asians. Fractional micro-plasma radio-frequency is a novel technology that produces minor ablation to the epidermis to promote rapid re-epithelialization, while the radio-frequency evoked thermal effect can stimulate regeneration and remodeling of dermal fibroblasts. OBJECTIVE To evaluate the clinical effectiveness and safety of micro-plasma radio-frequency for the treatment of facial acne scars in Chinese patients. MATERIALS AND METHODS A total of 95 patients with facial atrophic acne scars were treated by micro-plasma radio-frequency using three sessions at 2-month intervals. Patients were seen 1 week after each treatment and 1, 3, 6 months after the final treatment. Improvement was assessed by three independent dermatologists who compared photographs taken before the first treatment and 6 months after the last treatment. Adverse effects were evaluated by a dermatologist who did not participated in the study. Patients also provided self-evaluation of satisfaction levels at the last follow-up visit. RESULTS A total of 86 patients with atrophic acne scars completed the entire study. There was a significant improvement in acne scars after three treatments. The mean score of ECCA grading scale (Echelle d'Evaluation Clinique des Cicatrices d'Acné) was reduced from 107.21 to 42.27 (P < 0.05). A total of 15 of 86 patients showed more than 75% improvement, 57 patients showed 50-75% improvement, and 14 patients showed 25-50%. After three treatments, all subjects showed improvements in spots, large pores, texture, UV damage, red areas, and porphyrin fluorescence. Pain, erythema, edema, effusion, and scab formation were observed in all patients. The average pain score on a visual analog scale was 6.14 ± 1.12 and all patients tolerated the treatments. The average duration of erythema was 6.26 ± 0.92 days. Hyperpigmentation, hypopigmentation, infections, and worsening of scarring were not seen. All patients were either "very satisfied" or "satisfied" with the treatment outcomes. CONCLUSIONS Fractional micro-plasma radio-frequency is an effective and safe treatment for acne scars, and might be a good choice for patients with darker skin. Lasers Surg.

Abstract
INTRODUCTION Acne scarring is a very common problem, which can be extensive, and may lead to significant psychosocial morbidity. Multiple types of treatments are used to ameliorate atrophic scars with varying degrees of success. This paper provides an overview of the various energy-based modalities that are commonly employed against acne scarring. OBJECTIVES AND METHODS A comprehensive literature search of papers published since 2008 was performed in order to determine the efficacy and adverse reactions of commonly used energy-based treatments against post-acne scarring. RESULTS A total of 59 relevant articles were identified covering a multitude of different devices. DISCUSSION Ablative lasers seem to achieve the highest degree of efficacy, albeit this is associated with significant pain and downtime, and the risk for long-term pigmentary changes. Non-ablative fractional photothermolysis (FP) has a much safer profile but cannot achieve as good cosmetic results. The efficacies of fractional radiofrequency microneedling and radiofrequency are slightly inferior to that of FP but offer an even safer adverse profile. Little evidence is available on the remaining devices, with larger studies required in order to reach more solid conclusions. CONCLUSION Multiple devices have been used with varying levels of efficacy and very different safety profiles. There is an overall lack of high-quality evidence about the effects of different interventions. Furthermore, no standardised scale is available for acne scarring, leading to variability in evaluation and interpretation of data in different studies.

Abstract
BACKGROUND Laser and other energy devices are emerging, minimally invasive treatments for scars. Among the various techniques, fractional microplasma radiofrequency technology (FMRT) has proven to be an effective treatment option for various types of scars and skin conditions such as rhytids, striae distensae, and hyperpigmentation. OBJECTIVE This prospective clinical trial was designed to evaluate the efficacy and safety of FMRT for treating non-hypertrophic post-burn scars in the Asian population. METHOD All patients underwent three to five treatment sessions at various intervals of 8-16 weeks. The Patient and Observer Scar Assessment Scales (POSAS) [20] were used to evaluate changes in burn scars pre-and post-FMRT treatment. RESULTS A total of 95 patients completed the study. The overall response rate was 86.3% (82/95). The total POSAS scores before and after 6 months of treatment were 53.41 ± 6.28 and 46.35 ± 5.30, respectively. There was statistically significant improvement in scar color, thickness, and pliability. There was no improvement in vascularization, pain, or itching. Complications included prolonged post-inflammatory hyperpigmentation, acne eruption, herpes simplex eruption, and abnormal hair growth. No severe adverse events, such as acute skin infection, hypertrophic scarring, or depigmentation, were observed. CONCLUSION FMRT is an efficacious, safe treatment for non-hypertrophic burn scars in the Asian population. Lasers Surg. Med. 49:563-569, 2017. © 2017 Wiley Periodicals, Inc.

Abstract
BACKGROUND AND OBJECTIVE Fractionated photothermolysis (FP) has revolutionized modern laser technology. By creating selective columns of microthermal damage, fractionated devices allows for greater treatment depths to be achieved without the prolonged downtime and risk of complications seen in traditional fully ablative laser resurfacing. Fractional resurfacing is a proven method to treat a variety of cutaneous conditions. In the Caucasian patient, a wide range of devices and treatment settings can be utilized safely and effectively. However, ethnic skin requires special consideration due to its unique pigmentary characteristics and clinical presentations. In this review article, we detail the current indications and strategies to optimize results and mitigate complications when utilizing fractional resurfacing for the Asian patient. METHODS A review of the MEDLINE English literature was conducted on fractionated laser devices studied in the Asian population. Articles included describe non-ablative devices including fractionated erbium glass, thulium fiber, diode, and radiofrequency devices; and ablative devices including fractionated carbon dioxide (CO2 ) laser, erbium yttrium aluminum garnet and yttrium scandium gallium garnet (YSGG) laser. These data were integrated with the expert opinion of the authors. CONCLUSION Taking into account the unique characteristics and cosmetic concerns of the Asian population, fractional resurfacing can be considered a safe and effective option for the treatment of atrophic and hypertrophic scarring, and photorejuvenation in ethnic skin types. Select cases of melasma may be treated with fractionated non-ablative devices, but utilized with caution. The predominant complication associated with fractional resurfacing for these conditions is post-inflammatory hyperpigmentation (PIH) and rebound worsening of melasma. A greater number of treatments at lower density settings and wider treatment intervals typically produce the lowest risks of PIH without compromising treatment efficacy. Lasers Surg.

Abstract
BACKGROUND Acne scarring is a frequent complication of acne and resulting scars may negatively impact on an affected person's psychosocial and physical well-being. Although a wide range of interventions have been proposed, there is a lack of high-quality evidence on treatments for acne scars to better inform patients and their healthcare providers about the most effective and safe methods of managing this condition. This review aimed to examine treatments for atrophic and hypertrophic acne scars, but we have concentrated on facial atrophic scarring. OBJECTIVES To assess the effects of interventions for treating acne scars. SEARCH METHODS We searched the following databases up to November 2015: the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library (2015, Issue 10), MEDLINE (from 1946), EMBASE (from 1974), and LILACS (from 1982). We also searched five trials registers, and checked the reference lists of included studies and relevant reviews for further references to randomised controlled trials. SELECTION CRITERIA We include randomised controlled trials (RCTs) which allocated participants (whether split-face or parallel arms) to any active intervention (or a combination) for treating acne scars. We excluded studies dealing only or mostly with keloid scars. DATA COLLECTION AND ANALYSIS Three review authors independently extracted data from each of the studies included in this review and evaluated the risks of bias. We resolved disagreements by discussion and arbitration supported by a method expert as required. Our primary outcomes were participant-reported scar improvement and any adverse effects serious enough to cause participants to withdraw from the study. MAIN RESULTS We included 24 trials with 789 adult participants aged 18 years or older. Twenty trials enrolled men and women, three trials enrolled only women and one trial enrolled only men. We judged eight studies to be at low risk of bias for both sequence generation and allocation concealment. With regard to blinding we judged 17 studies to be at high risk of performance bias, because the participants and dermatologists were not blinded to the treatments administered or received; however, we judged all 24 trials to be at a low risk of detection bias for outcome assessment. We evaluated 14 comparisons of seven interventions and four combinations of interventions. Nine studies provided no usable data on our outcomes and did not contribute further to this review's results.For our outcome 'Participant-reported scar improvement' in one study fractional laser was more effective in producing scar improvement than non-fractional non-ablative laser at week 24 (risk ratio (RR) 4.00, 95% confidence interval (CI) 1.25 to 12.84; n = 64; very low-quality evidence); fractional laser showed comparable scar improvement to fractional radiofrequency in one study at week eight (RR 0.78, 95% CI 0.36 to 1.68; n = 40; very low-quality evidence) and was comparable to combined chemical peeling with skin needling in a different study at week 48 (RR 1.00, 95% CI 0.60 to 1.67; n = 26; very low-quality evidence). In a further study chemical peeling showed comparable scar improvement to combined chemical peeling with skin needling at week 32 (RR 1.24, 95% CI 0.87 to 1.75; n = 20; very low-quality evidence). Chemical peeling in one study showed comparable scar improvement to skin needling at week four (RR 1.13, 95% CI 0.69 to 1.83; n = 27; very low-quality evidence). In another study, injectable fillers provided better scar improvement compared to placebo at week 24 (RR 1.84, 95% CI 1.31 to 2.59; n = 147 moderate-quality evidence).For our outcome 'Serious adverse effects' in one study chemical peeling was not tolerable in 7/43 (16%) participants (RR 5.45, 95% CI 0.33 to 90.14; n = 58; very low-quality evidence).For our secondary outcome 'Participant-reported short-term adverse events', all participants reported pain in the following studies: in one study comparing fractional laser to non-fractional non-ablative laser (RR 1.00, 95% CI 0.94 to 1.06; n = 64; very low-quality evidence); in another study comparing fractional laser to combined peeling plus needling (RR 1.00, 95% CI 0.86 to 1.16; n = 25; very low-quality evidence); in a study comparing chemical peeling plus needling to chemical peeling (RR 1.00, 95% CI 0.83 to 1.20; n = 20; very low-quality evidence); in a study comparing chemical peeling to skin needling (RR 1.00, 95% CI 0.87 to 1.15; n = 27; very low-quality evidence); and also in a study comparing injectable filler and placebo (RR 1.03, 95% CI 0.10 to 11.10; n = 147; low-quality evidence).For our outcome 'Investigator-assessed short-term adverse events', fractional laser (6/32) was associated with a reduced risk of hyperpigmentation than non-fractional non-ablative laser (10/32) in one study (RR 0.60, 95% CI 0.25 to 1.45; n = 64; very low-quality evidence); chemical peeling was associated with increased risk of hyperpigmentation (6/12) compared to skin needling (0/15) in one study (RR 16.00, 95% CI 0.99 to 258.36; n = 27; low-quality evidence). There was no difference in the reported adverse events with injectable filler (17/97) compared to placebo (13/50) (RR 0.67, 95% CI 0.36 to 1.27; n = 147; low-quality evidence). AUTHORS' CONCLUSIONS There is a lack of high-quality evidence about the effects of different interventions for treating acne scars because of poor methodology, underpowered studies, lack of standardised improvement assessments, and different baseline variables.There is moderate-quality evidence that injectable filler might be effective for treating atrophic acne scars; however, no studies have assessed long-term effects, the longest follow-up being 48 weeks in one study only. Other studies included active comparators, but in the absence of studies that establish efficacy compared to placebo or sham interventions, it is possible that finding no evidence of difference between two active treatments could mean that neither approach works. The results of this review do not provide support for the first-line use of any intervention in the treatment of acne scars.Although our aim was to identify important gaps for further primary research, it might be that placebo and or sham trials are needed to establish whether any of the active treatments produce meaningful patient benefits over the long term.

Abstract
Scars are problematic for thousands of patients. Scarring is a natural part of the healing process after an injury. However, the appearance of a scar and its treatment depend on multiple factors and on the experience of the therapist and the options available. Despite a plethora of rapidly evolving treatment options and technical advances, the management of atrophic and hypertrophic scars remains difficult. Innovative technologies provide an attractive alternative to conventional methods in the treatment of scars. The purpose of this trial was to determine the clinical and histological results of a method of treatment that combines radiofrequency, ultrasound, and transepidermal drug delivery. This was a prospective study conducted on 14 patients with scars of different sizes, types, and characteristics. All patients underwent six treatment sessions with the Legato device. Atrophic scars were treated with retinoic acid and hypertrophic scars with triamcinolone. Photographs and biopsies were taken before treatment and at 6 months after the last treatment session. The scars improved significantly (P < 0.0001). The mean attenuation in the severity of scars was 67% (range: 50-75%), where 100% indicates complete disappearance of the scar. Clinical and histological images of scar tissue in six patients in whom attenuation in the range of 55-75% was achieved are shown. Biopsies show regenerative changes in the scar tissue, in both the epidermis and dermis. The method makes it possible to treat extensive, heterogeneous scars on different sites with good results that are similar and predictable.

Abstract
Infantile hemangiomas (IHs) are benign vascular tumors of infancy. Topical timolol has recently been reported to be an effective treatment for superficial IHs, although it failed to have an effect on deep IHs. This prospective study was aimed at evaluating the feasibility of ablative fractional laser-assisted drug delivery for enhancing topical timolol permeation into deep IHs. Nine patients ages 1 to 6 months with deep IHs were enrolled. A fractional carbon dioxide (CO2 ) laser system was applied to the skin surface of deep IHs using the DeepFx mode (25-30 mJ/pulse, 5% density, single pulse) at 1-week intervals. Topical timolol maleate 0.5% ophthalmic solution was applied under occlusion for 30 minutes four to five times per day for an average treatment duration of 14.2 weeks. Clinical improvement was evaluated according to a global score and the Hemangioma Activity Score (HAS). Four patients (44.4%) demonstrated excellent regression, four (44.4%) showed good response, and one (11.1%) experienced moderate regression. The HAS declined from 4.1 ± 0.7 at baseline to 1.7 ± 0.7 at 1 week (p < 0.001) and 1.4 ± 0.7 at 3 months (p = 0.03) after the last treatment procedure. Plasma timolol concentration was not detected in any of the patients after the first administration of topical timolol. No systemic complication or skin side effects were observed in any of the patients. Ablative fractional laser-assisted transdermal delivery of topical timolol is a safe and effective method for the treatment of deep IHs.

Abstract
BACKGROUND AND OBJECTIVE To determine the efficacy and safety of a new method for treating acne scarring over a short-term period of 2 months and a long-term period of 6 months. MATERIALS AND METHODS Six faces and 13 shoulders or backs for a total of 19 patients were treated, all of which displayed varying degrees of acne scarring, from moderate to severe. A newly developed high-power unipolar fractional ablative radiofrequency technology was used (iPixel™ RF, Alma Lasers, Caesarea, Israel), with acoustic pressure ultrasound guided dermal injection of the PixelTreat Scars preparation (Alma Lasers), through RF Pixel fractionated microchannels. All patients underwent four treatment sessions at 3-week intervals. RESULTS Significant improvement was observed in scarring, both on the face (P < 0.0001), and on the back and shoulders (P < 0.0001). After 2 months, the percentage of fading on total scarring was 57% on the face and 49% on the back and shoulders; after 6 months, the percentage increased to 62% on the face, and 58% on the back and shoulders, respectively. Patients reported to be Somewhat Satisfied (16%), Satisfied (53%), and Very Satisfied (31%). No unexpected side effects to the ablation and no hypersensitive reactions to PixelTreat Scars were observed. CONCLUSION The bimodal procedure is safe and effective in reducing acne scarring. This represents a new therapeutic alternative of great interest, to be used either as a monotherapy, or in combination with other treatments.

Abstract
BACKGROUND The most common side-effect of ablative fractional skin resurfacing in Asians is post inflammatory hyperpigmentation (PIH). Various attempts have been made to reduce the occurrence of PIH after laser treatment including sun avoidance, the use of preoperative and postoperative treatment regimens, and treatment using conservative energy settings and epidermal protection. OBJECTIVES To determine whether the use of broad-spectrum sunscreen with anti-inflammatory agents starting on the first day after fractional CO2 laser skin resurfacing reduces the incidence of post laser PIH. MATERIALS AND METHODS Thirty patients were treated with ablative fractional CO2 resurfacing on both sides of their faces at 10 mJ and 10% density. Each subject was randomly treated on one side of the face with petrolatum ointment four times a day for the first week after laser treatment and on the other side of the face with petrolatum ointment four times a day plus broad-spectrum sunscreen with anti-inflammatory agents in the morning starting on the first day after laser treatment. Transepidermal water loss was recorded at baseline and every day for 1 week. Melanin and erythema indexes were measured at baseline, 1-, 2-week, 1-, 2- and at 3-month post treatment. RESULTS Of the 30 patients involved in the study, 26 received the treatment and attended 1-, 2-week, 1-, 2- and 3-month post-treatment visits. Four patients were withdrawn from the study because they could not attend every follow-up visit. There was no statistically significant difference in transepidermal water loss at baseline, immediately after laser treatment, or at the D1 to D7 follow-up visits. Erythema index had no significantly statistical difference at baseline, 1-, 2- and at 3-month after laser treatment. Furthermore, there was a statistically significant difference in melanin index at 1-week post laser treatment between both sides (P = 0.001). Melanin index at the 1-week follow-up visit on the side treated with broad-spectrum sunscreen with anti-inflammatory agents starting on the first day after laser treatment was significantly less than the control side. CONCLUSION The use of broad-spectrum sunscreen with anti-inflammatory agents starting on the first day after ablative fractional skin resurfacing can decrease the incidence of PIH after laser treatment at 1-week postoperatively.

Abstract
This review examines the efficacy and safety of fractional CO2 lasers for the treatment of atrophic scarring secondary to acne vulgaris. We reviewed 20 papers published between 2008 and 2013 that conducted clinical studies using fractional CO2 lasers to treat atrophic scarring. We discuss the prevalence and pathogenesis of acne scarring, as well as the laser mechanism. The histologic findings are included to highlight the ability of these lasers to induce the collagen reorganization and formation that improves scar appearance. We considered the number of treatments and different laser settings to determine which methods achieve optimal outcomes. We noted unique treatment regimens that yielded superior results. An overview of adverse effects is included to identify the most common ones. We concluded that more studies need to be done using uniform treatment parameters and reporting in order to establish which fractional CO2 laser treatment approaches allow for the greatest scar improvement.

Abstract
BACKGROUND Treatment of acne scars with ablative fractional CO2 laser appears to be an effective and well-tolerated treatment. However, so far the influence of treatment interval has not been evaluated. OBJECTIVE To evaluate whether treatment of acne scars with fractional CO2 laser resurfacing at 1-month interval achieves better results with no difference in the occurrence of adverse effects, than treatment given at 3-months interval. METHODS Patients (n = 13) with symmetrical atrophic acne scars on right and left sides of the mid-face and lower-face were randomized to two fractional CO2 laser treatments at 1-month versus 3-month intervals. Blinded on-site evaluations were performed 1 and 6 months after the last treatment on 10-point scales. Endpoints were scar atrophy, patient satisfaction, and adverse effects. RESULTS Pre-operatively, acne scars were moderately atrophic (5.86 ± 1.87). After treatment acne scars appeared with less atrophy on both treated sides 1 month postoperatively (1-month interval 1.96 ± 1.23, P < 0.0001; 3-months interval 1.82 ± 1.08, P = 0.0006) and 6 months postoperatively (1-month interval 1.56 ± 1.24, P = 0.0021; 3-months interval 1.33 ± 1.66, P = 0.0002). The treatment interval did not influence the improvement of scar atrophy at any time postoperatively (P = 0.81). Patients were moderately and equally satisfied with the treatment result on facial sides (P = 0.93). Postoperative adverse effects were minor and not influenced by the treatment interval. CONCLUSIONS Fractional CO2 laser resurfacing improves atrophic acne scars and a treatment interval of either 1-month or 3-months does not seem to influence the improvement of scar atrophy nor the occurrence of postoperative adverse effects.
