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.

Abstract
In this report the use of eye cosmetic products and procedures and how this represents a lifestyle challenge that may exacerbate or promote the development of ocular surface and adnexal disease is discussed. Multiple aspects of eye cosmetics are addressed, including their history and market value, psychological and social impacts, possible problems associated with cosmetic ingredients, products, and procedures, and regulations for eye cosmetic use. In addition, a systematic review that critically appraises randomized controlled trial evidence concerning the ocular effects of eyelash growth products is included. The findings of this systematic review highlight the evidence gaps and indicate future directions for research to focus on ocular surface outcomes associated with eyelash growth products.

Abstract
Background Acne is a dermatologic condition with a high burden in terms of psychosocial consequences as a result of scars remaining on the skin. Its effects are severe in adolescence and finding treatments with short therapy courses, superior results, and fewer adverse effects are of high importance. Materials and Methods We included 30 individuals with acne vulgaris scars in Al-Zahra academic training hospital from June 2018 to Jan 2019. Each individual received both fractional CO2 and fractional Er:YAG lasers on right and left sides of the face, respectively. Three sessions of laser treatment were applied to each side with one-month intervals. Results were evaluated by patients according to subjective satisfaction and physicians' assessment and photo evaluation by two blinded dermatologists. Improvement was graded by a quartile grading scale: less than 25%: mild, 25% to 50%: moderate, 51% to 75%: good, and 76% to 100%: excellent response. Assessments were obtained at baseline and one month after the last visit. Results Based on subjective satisfaction (p < 0.05) and physicians' assessment (p < 0.01), fractional CO2 laser was significantly more effective than Erbium:YAG laser. Also, Post-treatment side effects were mild and transient in both groups. Conclusion Laser therapies are common in the treatment of scars and each modality has special advantages and disadvantages. Choosing among them should be based on various criteria. Fractional CO2 lasers have been revealed favorable results in most reports. Large comprehensive trials could help experts in choosing among alternatives for different subgroups.

Abstract
Acne scarring is a common disfiguring complication of acne, and fractional lasers are widely applied in improving it. This study is to compare the efficacy and safety of fractional non-ablative 1927 nm thulium laser (FTL) and fractional ablative 2940 nm Er:YAG laser (FEL) in the treatment of acne scarring. Subjects with moderate or severe atrophic facial acne scarring received 3 sessions of FTL on the left side of face and FEL on the right side of face at an average interval of 4-6 weeks. Major assessments included Goodman&Baron quantitative global scarring grading system (GBS), self-rated improvement and satisfaction score. Twenty-seven subjects completed the study; for FTL side, average GBS decreased from 11.15 ± 5.04 at baseline to 7.07 ± 4.87 with an improvement percent of 36.54%; for FEL side, average GBS decreased from 10.81 ± 4.46 to 7.00 ± 4.07 with an improvement percent of 35.27%. Adverse effects include transient pain, erythema, edema, and increase of acne. No significant difference was found between two lasers. Both FTL and FEL improved atrophic acne scarring and were well-tolerated. Increase of acne during laser treatment may have a negative impact on efficacy. Trial registration number was NCT04813419 and date of registration was 19th, March, 2021, retrospectively registered.

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
PURPOSE The primary objective was to evaluate the efficacy and safety of Er:YAG laser treatment for meibomian gland dysfunction (MGD) in a prospective study. METHODS A total of 128 eyes from 64 patients with MGD were enrolled to receive either three Er:YAG laser treatments with meibomian gland expression (MGX) or MGX-alone treatment sessions at 3-week intervals. The Standard Patient Evaluation of Eye Dryness (SPEED) validated questionnaire; fluorescein breakup time of the tear film (FBUT); corneal fluorescein staining (CFS); lid margin abnormalities; meibomian gland morphology (meiboscore); lower tear meniscus height (TMH); and assessment of 15 meibomian glands in the lower eyelids, including total meibomian gland secretion quality (TMGS), the number of glands secreting any liquid (GSAL), and the number of glands yielding optimal clear liquid secretion (GYCL), were assessed at day (D)0, D21, D42, and D63 for the Er:YAG-MGX group and D0 and D63 for the MGX group. RESULTS At D63, significant decreases in SPEED scores and lid margin abnormalities as well as significant increases in FBUT, TMGS, and GSAL were observed in both groups (all p < 0.05). The Er:YAG-MGX group showed a significantly better improvement in SPEED scores, TMGS, and GYCL than the MGX group (all p < 0.05). CONCLUSION Although preliminary, the study results of Er:YAG laser treatment for dry eye syndrome caused by MGD are promising. Er:YAG laser treatment may be a new direction for managing MGD.

Abstract
Importance Evidence is robust for the effectiveness of microneedle therapy in the management of postacne atrophic scarring. A home-based topical treatment with an efficacy comparable to microneedling would be a useful addition in the armamentarium of acne scar management. Objective To compare the efficacy of topical tazarotene gel, 0.1%, with microneedling therapy in the management of moderate to severe atrophic acne scars. Design, Setting, and Participants Prospective, observer-blinded, active-controlled, randomized clinical trial with 6 months of follow-up conducted between June 2, 2017, and February 28, 2018, at a tertiary care hospital in India. Thirty-six patients with grade 2 to 4 facial atrophic postacne scars and without a history of procedural treatment of acne scars within the previous year were recruited. Analyses were conducted using data from the evaluable population. Interventions Both halves of each participant's face were randomized to receive either microneedling or topical tazarotene therapy. Microneedling was conducted on 1 side of the face with a dermaroller having a needle length of 1.5 mm for a total of 4 sessions during the course of 3 months. Participants were instructed to apply topical tazarotene gel, 0.1%, to the other side of the face once every night during this same period. Main Outcomes and Measures Patients were followed up at 3 and 6 months by a blinded observer, and improvements in acne scar severity based on Goodman and Baron quantitative and qualitative scores and a subjective independent dermatologist score (range, 0-10, with higher scores indicating better improvement) were assessed. Patient satisfaction was assessed using a patient global assessment score (ranging from 0 for no response to 10 for maximum improvement) at these follow-up visits. Results There were 36 participants (13 men and 23 women; mean [range] age, 23.4 [18-30] years), and the median (interquartile range [IQR]) duration of acne was 6 (4-8) years. For the 34 participants included in the complete data analyses, the median (IQR) quantitative score for acne scar severity at the 6-month follow-up visit following treatment with either tazarotene (from a baseline of 8.0 [6.0-9.8] to 5.0 [3.0-6.0]) or microneedling (from a baseline of 7.0 [6.0-10.8] to 4.5 [3.0-6.0]) indicated significant improvement (P < .001) that was comparable for both treatments (median [IQR] change in severity score from baseline, 2.5 [2.0-4.0] vs 3.0 [2.0-4.0]; P = .42). By contrast, median qualitative acne scar scores were the same for both treatment groups at baseline and did not significantly change following either treatment. Conclusions and Relevance The present clinical trial showed comparable outcomes of both treatments for the overall improvement of quantitative facial acne scar severity. Level of Evidence 1. Trial Registration ClinicalTrials.gov identifier: NCT03170596.

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
BACKGROUND AND OBJECTIVE The aging of human skin includes intrinsic aging and photo-aging, which are characterized by a decrease in collagen and the deposition of abnormal elastic fibers. Intense pulsed light (IPL) sources are widely used in medicine to treat various cosmetic problems, including photo-damaged skin. Few studies have examined the microscopic changes produced by IPL. The objective of this study was to quantitatively evaluate the effects of IPL on collagen and elastic fibers in mice. MATERIALS AND METHODS Forty female BALB/c mice were divided into four subgroups. Group 1 was the control group (n = 10), and groups 2, 3, and 4 were treatment groups (n = 10 in each group). Group 2 received one treatment, group 3 received two treatments, and group 4 received three treatments every 2 weeks. Skin tissue was obtained from irradiated areas 24 hours after the last treatment in each mouse. Collagen fibers were identified using the picrosirius red method. Elastic fibers were marked by Weigert-oxone stain. All samples were analyzed and quantified by a light microscope using analyzer system images. RESULTS Group 4, which received three IPL treatments, showed significant quantitative increases in both collagen fibers (P < 0.05) and elastic fibers (P < 0.01). Collagen fibers demonstrated a better parallel distribution in relation to the epidermis. CONCLUSION IPL treatment significantly increased the number of collagen and elastic fibers within the dermis and improved the parallel distribution of collagen fibers in relation to the epidermis. These results were evident after three IPL treatments. Lasers Surg. Med. © 2018 Wiley Periodicals, Inc.

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 Platelet-rich plasma (PRP) which contains large amounts of growth factors has been tried to enhance therapeutic efficacy of laser treatment for acne scar with unknown underlying mechanism. OBJECTIVES The present study was conducted to investigate the molecular mechanism of increased clinical efficacy of PRP when combined with fractional laser treatment for treating acne scars. METHODS Subjects with mild to moderate acne scars were treated with two sessions of fractional CO2 laser therapy given with and without co-administration of PRP. Skin biopsy specimens were obtained at baseline, 1, 3, 7, and 28 days for investigation of molecular profiles associated with skin changes produced by laser plus PRP treatment. RESULTS The PRP treatment increased clinical efficacy with decreased severity of adverse effects such as erythema, swelling and oozing. Productions of TGFβ1 and TGFβ3 proteins were more highly elevated on the PRP-treated side of the face compared to the control side at day 28. Furthermore, PRP-treated side showed significant increase of c-myc, TIMP, and HGF expression. Experimental fibroblast culture model was also used. PRP administration after laser irradiation increased expressions of p-Akt, TGFβ1, TGFβ3, β-catenin, collagen 1, and collagen 3 in both dose-dependent and time dependent manners in fibroblast. Moreover, we acquired clinical and histological data through randomized control clinical trial. CONCLUSION Taken together with human study results combined with the data from cell experiments we suggest that PRP treatment increased fibrogenetic molecules induced by fractional CO2 laser, which have association with clinical effect.

Abstract
Background and Objectives Fractional treatment with a dual wavelength 1,064 and 532 nm picosecond‐domain laser, delivering a 10 × 10 array of highly focused beamlets via a holographic optic, was investigated for the treatment of acne scars. Study Twenty‐seven of 31 subjects completed the study, 19 were treated using 1,064 nm and 8 were treated at 532 nm, all having four‐monthly treatments. Blinded evaluation of digital images by three physician evaluators comparing pre‐ and 3‐month post‐treatment images measured efficacy using a 10‐point scale. Subject self‐assessment of treatment effects were also recorded. Safety was measured by recording subject discomfort scores and adverse effects. Results Blinded reviewers correctly identified the baseline image in 61 of the 81 image sets (75%), and baseline acne scar scores were 1.8 ± 0.7 and 1.8 ± 0.5 for the 1,064 and 532 nm cohorts, and decreased to 1.1 ± 0.5 (P < 0.001) and 1.1 ± 0.0 (P < 0.005), respectively. Post‐treatment erythema, mild edema, and petechiae were the only side effects noted. Conclusion The 1,064 and 532 nm picosecond‐domain laser incorporating a 10 × 10 holographic beam‐splitting handpiece was found to be safe and effective for the treatment of facial acne scars. The treatments were well tolerated and the subjects experienced little to no downtime. Lasers Surg. Med. 49:796–802, 2017. © 2017 The Authors.

Safety of non-ablative fractional laser for acne scars within 1 month after treatment with oral isotretinoin: A randomized split-face controlled trial. Lasers Surg Med 2017; 49:886-890.

Abstract
BACKGROUND AND OBJECTIVE Based on reports of poor wound healing and scarring, it is currently recommended that patients wait 6 months after completion of oral isotretinoin therapy before the safe initiation of laser treatment. Our aim was to evaluate the safety of non-ablative fractional laser (NAFL) treatment for acne scars within 1 month after isotretinoin therapy. STUDY DESIGN/METHODS This was a randomized split-face controlled trial involving 10 patients with acne scars who had completed isotretinoin treatment. All patients received three treatments each spaced 4 weeks apart with an erbium-doped 1550 nm NAFL on one side of the face within 1 month after isotretinoin therapy. The untreated side acted as a control. Wound healing and adverse effects as well as acne scar improvement were evaluated by two blinded dermatologists. RESULTS All patients demonstrated normal wound healing post NAFL treatments, and neither hypertrophic scars nor keloids were observed. Acne scar improvement was satisfactory. CONCLUSION NAFL treatment for acne scarring appears to be well tolerated within 1 month of completing isotretinoin treatment. Dermatologists should reevaluate the current recommendation to wait 6 months after isotretinoin treatment for acne scar revision with lasers. Other larger studies are necessary to further challenge this dogma. Lasers Surg. Med. 49:886-890, 2017. © 2017 Wiley Periodicals, Inc.
