The efficacy and safety of low- versus high-fluence fractional picosecond Nd:YAG 1064-nm laser in the treatment of acne scars: A randomized split-face comparison study. PHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE 2024; 40:e12922. [PMID: 37898983 DOI: 10.1111/phpp.12922] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 10/19/2023] [Accepted: 10/24/2023] [Indexed: 10/31/2023]
Abstract
BACKGROUND Differences in clinical efficacy based on the fluence of fractional picosecond laser treatment for acne scars are unknown. OBJECTIVE To compare the efficacy and safety of low-fluence versus high-fluence fractional picosecond Nd:YAG 1064-nm laser treatment in acne scar patients. METHODS In this 12-week, investigator-blinded, randomized, split-face study, 25 patients with moderate-to-severe acne scars received three sessions of high-fluence laser treatment (1.0 J/cm2 ) on one side of their face and low-fluence (0.3 J/cm2 ) on the other side every 4 weeks. Patients were assessed using acne scar counts, the scar global assessment (SGA), and the ECCA scar grading scale every 4 weeks. The histological analysis compared the acne scars obtained before and 4 weeks after treatment. RESULTS At their last visit, 88.00% and 92.00% of the subjects achieved >30% reduction in scar counts on the low- and high-fluence sides, respectively, without a significant difference between the two sides. On both sides, the scar counts, SGA, and ECCA score significantly improved 4 weeks after the last treatment. Although the high-fluence side showed a greater reduction in scar counts (-66.73%) than the low-fluence side (-62.13%), the two sides had no significant difference in the grading scores. The high-fluence side showed significantly more severe pain and higher side-effect scores immediately and 4 weeks after treatment. Histological analysis revealed a significantly increased collagen, elastin, and vimentin expression after treatment on the low-fluence side. CONCLUSIONS The low-fluence setting demonstrated comparable efficacy and superior safety in treating acne scars compared with the high-fluence setting.

Abstract
Acne vulgaris (AV) is the eighth most common disease in the world. This condition can impair the affected patients' social and psychological functioning and lower their quality of life. In general, scar reduction, rather than complete scar removal, is the aim of AV treatment. Dermal abrasion, chemical peeling, laser resurfacing, subcision, punch methods, tissue-improving substances, and dermal fillers are the currently available therapeutic options. In this study, we focused on the rapidly developing field of dermal fillers used alone or in combination with other therapies to reconstruct skin affected by acne scars and to evaluate the improvement of facial appearance after using different types of dermal fillers.

Abstract
OBJECTIVE Acne scars carry a huge physical and psychological impact on people. This article aims to evaluate the role of fractional radiotherapy in treatment of atrophic acne scars. The main objective includes providing an up-to-date review of existing literature, presenting the most significant studies conducted in this field. METHODS In order to study the impact of fractional radiotherapy on the appearance of atrophic acne scars, we conducted a search on Pubmed using the keywords "fractional radiotherapy", combined with/or "acne", "atrophic acne scars" and "acne scars" and found 75 papers, from which we selected 39. RESULTS There are several therapeutic approaches for the improvement of acne scars with variable results and possible side effects. Fractional radiofrequency system has been used widely in the last years, as it turned out to be an effective treatment method, either in combination with other modalities, or alone. CONCLUSION There are no generalized clinical guidelines adopted to standardize atrophic acne scar treatment. The multiple therapeutic options available create a dilemma in choosing the proper method in order to enhance its efficacy and to minimize its risks. The accumulated experience in nonablative collagen stimulating devices like fractional radiofrequency has proven that thickening of interstitial fibers in the dermis is possible with a controlled thermal injury, without epidermal damage and development of side effects.

Abstract
Fractional CO2 laser is a good option for treating acne scars. However, the clinical efficacy of this treatment modality requires further evidence. To perform a meta-analysis to assess clinical improvements in acne scars with fractional CO2 laser and non-CO2 laser therapies. Databases (PubMed, Embase, Cochrane Library) were searched using the search strategy to identify eligible studies. All statistical analyses were performed using the Review Manager 5.0, and a meta-analysis was conducted to assess the effects of fractional CO2 laser used as a treatment for acne scars. Eight studies were included for further analysis. There was no significant difference between fractional CO2 laser and non-CO2 laser therapies in terms of clinical improvement, observer assessment (P = .19), patient assessment (P = .91), and incidence of post-inflammatory hyperpigmentation (P = .69). The subgroup analyses showed that the duration of follow-up had little effect on the evaluation of treatment effect. The efficacy of fractional CO2 laser therapy in acne scars appeared to be equal to that of non-CO2 laser therapies. More well designed randomized controlled trials and more credible and standard evaluation criteria are needed, and the efficiency of combination therapy requires further analysis.

Abstract
Background: Scarring is one of the most dreadful complications of acne for which patients seek surgical treatment. Objective: The aim of this research was to study the morphological features of acne scarring and the relationship between severity of acne and its treatment with type and severity of acne scars. Materials and Methods: This was a hospital-based, noninterventional, cross-sectional study carried out over a period of 1 month on 100 patients with post-acne scarring. A morphological evaluation of the types, sites, and severity of acne scars was done, and details of the severity and treatment of acne were recorded. Results: Of 100 patients included in the study, 61 were male and 39 were females. Females had an earlier onset of acne (15.8 years) as compared to males (16.5 years). The mean duration of active acne was longer in males (99.3 months) than that in females (74.4 months). Male patients had more severe acne vulgaris as compared to females (P = 0.0001). Of 100 patients, 52 started treatment 1 year after the onset of acne, and 18 patients had never taken any anti-acne medication. Morphologically, majority of post-acne scars were ice pick scars in 94% patients, followed by rolling scars in 86%, boxcar scars in 54%, and keloidal scars in 10% patients. Male patients had more severe acne scarring than females (P < 0.05). Of 54 patients with severe acne, 22 progressed to moderate grade and 32 patients progressed to severe grade of acne scarring. Significant reduction in the severity of acne scarring was observed in patients who received isotretinoin as compared to that in patients who received oral antibiotics. Conclusion: Majority of patients with active acne delay treatment, which leads to increased acne scarring. Ice pick scars are the most common type of acne scars, and keloidal scars are more common in males. Males have a longer duration of acne, they delay treatment, and have more severe acne scarring. Early introduction of oral isotretinoin may help to reduce the severity of acne scarring. Public education is essential to urge patients to seek early and appropriate treatment of acne that can reduce the incidence and severity of acne scarring and its psychosocial consequences.

Abstract
BACKGROUND Chemical reconstruction of skin scars (CROSS) applies a high strength acid focally to treat atrophic scars. Although this method has gained popularity over the past two decades, no standardized treatment guideline exists for CROSS method in the treatment of atrophic scars. AIMS The purpose of this comprehensive review was to evaluate the indications, detailed techniques, efficacy, and safety of CROSS method. MATERIALS AND METHODS An extensive literature review was conducted to identify articles relating to CROSS method for atrophic scars from 2002 to 2018. RESULTS The literature search yielded 19 articles meeting criteria. CROSS method has been used for the treatment of acne scars, varicella scars, enlarged pores, and depressed surgical scars. In studies using the quantile grading scale for acne scars, 60%-100% of patients showed >25% improvement. In two studies for varicella scars, 83%-100% of patients showed >25% improvement. CROSS method seems to be effective specifically for ice-pick scars. It is well tolerated and safe in Fitzpatrick skin phototypes I-V. Most reported complications are temporary and include postinflammatory dyspigmentation, erythema, pain, pruritus, infection, and widening of scars. CONCLUSION This literature review suggests that CROSS method is a safe and effective treatment for atrophic scars, especially ice-pick scars, in skin types I-V. However, current published works have several limitations, including small sample sizes, lack of control group, different concentrations of acid, different frequency of treatments, and follow-up periods. Larger, randomized, controlled studies are needed to elucidate the optimal treatment protocol of CROSS method.

Abstract
BACKGROUND Patients with acne scarring often have several types of acne scars, and combination therapies have demonstrated superior success to single treatment modalities. Chemical reconstruction of skin scars (CROSS) has gained popularity as the treatment for ice-pick scars and fractionated laser therapy for rolling and boxcar scars. However, no study has looked at combination therapy with CROSS and fractionated nonablative laser for the treatment of atrophic acne scars. AIMS We sought to evaluate the efficacy and safety of combination therapy with CROSS and fractionated nonablative laser for atrophic acne scars. METHODS We conducted a retrospective analysis of patients treated with CROSS followed by fractionated nonablative laser treatment in the same visit for acne scars from 2016 to 2020. Treatment efficacy, defined as the percentage improvement in the appearance of acne scars, was assessed using a 5-point scale: score 0 (worsening or 0% improvement), 1 (1% - 25%), 2 (26% - 50%), 3 (51%-75%), and 4 (76%-100%). RESULTS Twenty-five patients (14 females and 11 males, Fitzpatrick Skin Type II -V) were enrolled. The average improvement score was 2.07 after 3 sessions and 2.78 after 5 sessions. All subjects reported satisfaction, while 24% were very satisfied. There were no permanent adverse effects, and only one patient developed a temporary hypertrophic scar. CONCLUSION We concluded that combination therapy with CROSS and fractionated nonablative laser in the same visit is an effective and safe treatment option for atrophic acne scars in patients with various skin types, including skin of color.

Abstract
BACKGROUND Acne scarring affects most patients with acne and have a negative impact on quality of life. New effective treatment options offering minimal downtime are therefore needed. OBJECTIVE To evaluate improvement in overall facial appearance after hyaluronic acid (HA) treatment of atrophic acne scars. METHODS Twelve subjects with moderate-to-severe acne scars were treated at 3 sessions 4 weeks apart. At each session, up to 2-mL HA gel was injected into each side of the face. Acne scar severity, global facial aesthetic improvement, and subject satisfaction were assessed up to 36 weeks after treatment. Safety assessments included subject diaries and adverse events. RESULTS The overall facial appearance and the appearance of atrophic acne scars improved after treatment. Scar severity and subject satisfaction with the overall facial appearance and with the sensation and perception of the skin improved in most subjects. Subjects' self-esteem and self-confidence also improved. Adverse events were typically mild to moderate, expected, and procedure-related. CONCLUSION Hyaluronic acid gel injections were effective and safe for treatment of moderate-to-severe atrophic acne scars. The treatment effect developed gradually over time with the highest improvement observed at the end of the study.

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
This review focuses on the treatment options for adult female patients with acne. Acne in adult female patients may start during adolescence and persist or have an onset in adulthood. Acne has various psychosocial effects that impact patients’ quality of life. Treatment of acne in adult women specifically has its challenges due to the considerations of patient preferences, pregnancy, and lactation. Treatments vary widely and treatment should be tailored specifically for each individual woman. We review conventional therapies with high levels of evidence, additional treatments with support from cohort studies and case reports, complementary and/or alternative therapies, and new agents under development for the treatment of patients with acne.

Abstract
The aim of this study was to evaluate the efficacy and safety of fractional carbon dioxide laser for the treatment of acne scars. Thirty-one participants, 15 female and 16 male, whose mean age was 34.84 ± 10.94 years, were included in this prospective study. The study took place between 2012 and 2016. Participants were evaluated with the "ECCA Grading Scale" before the first session, 3 months (short-term evaluation) and 3 years after the last session (long-term evaluation). Participants received two or three treatment sessions at 4-week intervals, with a 10,600 nm fractional carbon dioxide laser with pulse energies ranging between 100 and 160 mJ, 120 spot type, 75-100 spot/cm2 density, and 30 W power. Self-assessments by the participants were done 3 months and 3 years after the last session. The mean ECCA score was 107.90 ± 39.38 before the first session, and 82.17 ± 36.23 at the time of short-term evaluation (p = 0.000). The grade of improvement at the short-term evaluation was as follows: no improvement, mild, moderate, and significant improvement for 7 (22.6%), 11 (35.5%), 9 (29%), and 4 (12.9%) of the participants, respectively. Regarding self-assessments, 80.6 and 61.3% of the participants rated themselves as having at least mild improvement at the short-term and the long-term follow-up periods, respectively. The results of this study suggest that fractional carbon dioxide laser is an efficient treatment option for acne scars. Furthermore, self-assessment results show that more than half of the participants still experience at least mild improvement at the end of 3 years.

Abstract
Acne is a common condition that can result in permanent scarring. We have
performed a comprehensive literature search of the last 10 years in order to
determine the efficacy and side effects of commonly used treatments against
post-acne scarring. A total of 36 relevant articles were identified on the
following interventions: subcision (10), dermabrasion (one), microneedling
(eight), dermal fillers (five), and chemical peeling (12). Post acne scarring is
a common and challenging condition with no easy and definitive solution. The
above interventions have been used with varying degrees of efficacy, each having
both pros and cons. All have been deemed to be safe with few and transient
adverse reactions. However, further trials with larger number of patients are
necessary in order to reach more concrete conclusions regarding their
efficacy.

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
Background: Scarring following acne vulgaris is common and can be of profound psychosocial consequence. Aims and Objectives: We have clinically noted a variant of acne scarring, overlooked by previous categorisation schemes, which we have denominated as papular acne scars of the nose and chin. We sought to characterise these novel entities further. Materials and Methods: Initially, we identified 14 patients with papular acne scars of the nose and chin in a cosmetic dermatology clinic, of whom two were female and rest were male. We then prospectively evaluated 100 consecutive patients attending our tertiary referral acne isotretinoin clinic and 49 patients attending a general dermatology clinic. Results: Amongst 149 patients, from a general dermatology and tertiary acne clinic, soft papular scars were noted in four patients, distributed on the nose and chin. Three of the four patients were male, three patients had additional acne scars and the median age was 23.5. Conclusions: We have identified 18 patients with papular acne scars of the nose and chin and propose that this new category should be added to acne scarring classification schemes. Future work should be directed at corroborating the epidemiology of such lesions and describing effective treatment modalities.
