Abstract
Superficial chemical peels are one of the most popular skin resurfacing procedures in a dermatologists' clinic today due to quick application process, fast recovery, good patient acceptance, and excellent cosmetic results. The role of various peeling agents like glycolic acid, salicylic acid, trichloroacetic acid, Jessner's solution, retinoic acid, and lactic acid in the management of melasma has been established as that of an additional or maintenance therapy. This article details the current evidence and recommendations for the use of chemical peels in the treatment of melasma, a chronic and recurrent hyperpigmentary disorder.

Efficacy and safety of metformin for melasma treatment: a systematic review and meta-analysis. Front Pharmacol 2023; 14:1281050. [PMID: 38192412 PMCID: PMC10773746 DOI: 10.3389/fphar.2023.1281050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Accepted: 11/28/2023] [Indexed: 01/10/2024] Open
Abstract
Objective: Metformin has recently been demonstrated to have an anti-melanogenic activity. Nevertheless, clinical evidence of the effectiveness of metformin in melasma is lacking. The objective of this study was to assess the efficacy and safety of metformin in the treatment of melasma. Methods: MEDLINE, Embase, PubMed, Cochrane Library (CENTRAL), Scopus, CINAHL, and grey literature databases were searched to 4 October 2022 and updated on 26 February 2023. Randomized controlled trials (RCTs), quasi-RCTs, observational studies, case series, and case reports investigating the efficacy and safety of metformin for melasma were included. The Melasma Area Severity Index (MASI) scores that changed from baseline were pooled using fixed-effects model and expressed as standardized mean differences (SMDs) and 95% confidence intervals (CIs). Results: Three RCTs including 140 patients with melasma were included. The results demonstrated that after 8 weeks, 15% topical metformin significantly reduced the Melasma Area Severity Index (MASI) score compared to placebo (1 trial; n = 60; MD, -0.56; 95% CI, -1.07 to -0.04; p = 0.034). Furthermore, when compared to triple combination cream (TCC), 30% topical metformin demonstrated similar efficacy in reducing the MASI score after 8 weeks (2 trials; n = 80; MD, 0.19, 95% CI, -0.25 to 0.63; p = 0.390). Patients using 30% topical metformin had fewer adverse events compared to TCC users, although no statistical difference was found. Conclusion: Topical metformin was as effective as triple combination cream (TCC) in decreasing changes in the MASI score in patients with melasma, with minimum adverse events. Further studies with larger sample sizes, longer follow-up times, and well-designed trials are required. Systematic Review Registration: Identifier PROSPERO (CRD42022351966).

Abstract
Background: Melasma results from the imbalance of the mechanisms that regulate skin pigmentation, causing the appearance of hyperpigmented patches. Treatment includes topical and oral agents, chemical peelings, microneedling, and laser therapy. The picosecond laser was developed to minimize pain and skin discoloration, which can sometimes be associated with laser treatments. It emits short pulses of energy that last from 300 to 500 picoseconds, leading to a more significant fragmentation of melanin, with miniminal risk of scarring and thermal lesions in the surrounding skin. Objective: The authors aimed to review the use of picosecond laser in the treatment of melasma and further provide an overview of the other current available options. Conclusions: While the use of picosecond laser for the treatment of melasma has yielded good results, further studies with longer follow-up periods and a higher number of patients are needed.

Abstract
BACKGROUND Due to relapsing nature of melasma with significant impact on quality of life, an objective measurement score is warranted, especially to follow-up the patients with melasma and their therapy response in a quantitative and precise manner. AIMS To prove concordance of skin hyperpigmentation index (SHI) with well-established scores in melasma and demonstrate its superiority regarding inter-rater reliability. Development of SHI mapping for its integration in common scores. METHODS Calculation of SHI and common melasma scores by five dermatologists. Inter-rater reliability was assessed by intraclass correlation coefficient (ICC) and concordance by Kendall correlation coefficient. RESULTS Strong concordance of SHI with melasma area and severity index (MASI)-Darkness (0.48; 95% CI: 0.32, 0.63), melasma severity index (MSI)-Pigmentation (0.45; 95% CI: 0.26, 0.61), and melasma severity scale (MSS) (0.6; 95% CI: 0.42, 0.74). Using step function for mapping SHI into pigmentation scores showed an improvement of inter-rater reliability with a difference in (ICC of 0.22 for MASI-Darkness and 0.19 for MSI-Pigmentation), leading to an excellent agreement. CONCLUSION Skin hyperpigmentation index could be an important additional cost-and time-conserving assessment method, to follow-up the patients with melasma undergoing brightening therapies in clinical studies, as well as in routine clinical practice. It is in strong concordance with well-established scores but superior regarding inter-rater reliability.

A randomized, open-label study to compare two different dosing regimens of oral tranexamic acid in treatment of moderate to severe facial melasma. Arch Dermatol Res 2023; 315:1831-1836. [PMID: 36757440 DOI: 10.1007/s00403-023-02549-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 01/04/2023] [Accepted: 01/22/2023] [Indexed: 02/10/2023]
Abstract
Oral tranexamic acid (TXA) demonstrates promising results in melasma management. However, no clear consensus on the dosing and duration of maintenance doses of TXA therapy in melasma exists. In this study, we intend to evaluate and compare the efficacy of two different TXA dosing regimens in patients with melasma using the mMASI score. This was a randomized, open-label study wherein 50 patients (age > 18 years) with moderate to severe melasma were randomized into group A (250 mg TXA twice a day) and group B (500 mg TXA twice a day). Treatment was administered for 12 weeks and later followed up 4-weekly for next 12 weeks. The primary outcome measure was proportion of patients achieving 75% reduction in modified Melasma area and severity index (mMASI-75) at 12 weeks from baseline, reduction in mMASI and melasma quality of life (MelasQOL) score at 12 and 24 weeks. To assess the rate of relapse by end of 12 weeks post-treatment. Among 50 patients, proportion of patients achieving mMASI-75 at 12 weeks were 20% and 25% in group A and B, respectively (p-0.71). Both groups showed a significant reduction in mean mMASI (4.8 ± 2.2 in group A and 6.8 ± 3.4 in group B; p-0.02) at 12 weeks of treatment. mMASI remained stable after 12 weeks of follow-up and was 4.9 ± 2.43 and 4.93 ± 2.85 in group A and B, respectively (p-0.97). The mean percentage reduction in MelasQOL in group A and B were 41.8 ± 15.3 and 29.5 ± 21.5, respectively (p-0.03). No adverse effects were observed in both groups. Relapse rates was very less and comparable between both groups. Thus, we conclude that both dosing regimens showed comparable efficacy in terms of mMASI reduction at 12-weeks and the improvement achieved was well maintained even after 12-weeks of discontinuing treatment with very few patients relapsed. Hence, lower doses of TXA are equally effective and safe compared to higher doses and not all patients might require tapering or dosing maintenance.

Abstract
INTRODUCTION Photobiomodulation (PBM) has been suggested as an alternative treatment for melasma. In vitro studies have shown PBM with amber light inhibits the tyrosinase enzyme, induces autophagy and reduces the melanin content, but randomised controlled clinical trials are still needed. This study aims to evaluate the efficacy of amber PBM (590 nm) in the treatment of melasma compared with liposomal tranexamic acid. METHODS AND ANALYSIS This study is a controlled, randomised, double-blind, non-inferiority trial. This study will be performed in two centres (Universidade Nove de Julho Facility, Campus Vergueiro, and Galache Odontology Clinic, São Caetano do Sul, both in São Paulo State, Brazil). The sample (54 participants) will be divided into two groups in a 1:1 ratio; one group will receive active PBM and a placebo cosmetic and the other will receive sham PBM and liposomal tranexamic acid. Women presenting facial melasma, aged 35-50 years, with skin phototypes II-IV, will be eligible for inclusion. Women who use oral contraceptives, intrauterine devices, hormone replacement or photosensitive drugs, those with autoimmune disease and those who have undergone facial treatments in the last 3 months will be excluded from the study. The participants will receive PBM weekly for 12 weeks and will use the cosmetic two times per day at home during this period. The severity of melasma will be evaluated through the Melasma Area and Severity Index (MASI) as the primary outcome; pigmentation of the epidermis evaluated by corneomelametry, the photographic records, the global diagnosis of the face and the quality-of-life questionnaire (Brazilian Portuguese version of the Melasma Quality of Life Questionnaire) will assessed as secondary outcomes. All assessments will be made before starting the study (week 0), mid-study at 6 weeks and at the completion of treatment (week 12). MASI will also be evaluated during follow-up (weeks 16 and 20). The data will be analysed based on the intention-to-treat analysis using a generalised mixed model, and α <0.05 will be considered statistically significant. ETHICS AND DISSEMINATION The protocol was approved by the Research Ethics Committee of Universidade Nove de Julho (5 332 384). All participants will fill out the patient informed consent form. The results obtained in this trial will be presented at conferences and submitted for publication. TRIAL REGISTRATION NUMBER ClinicalTrials.gov Registry (NCT05326997).

Abstract
BackgroundIncreasing numbers of studies demonstrated that picosecond lasers (Picos) were effective and safe for melasma. However, A limited number of randomized controlled trials (RCTs) regarding Picos contribute to a modest level of evidence. Topical hydroquinone (HQ) remains to be the first-line therapy.ObjectiveTo compare the efficacy and safety of non-fractional picosecond Nd:YAG laser (PSNYL), non-fractional picosecond alexandrite laser (PSAL), and 2% HQ cream in the treatment of melasma.MethodSixty melasma patients with Fitzpatrick skin types (FST) III-IV were randomly assigned to the PSNY, PSAL, and HQ groups at a 1:1:1 ratio. Patients in PSNYL and PSAL groups received 3 laser sessions at 4-week intervals. The 2% HQ cream was applied twice daily for 12 weeks in patients of the HQ group. The primary outcome, the melasma area and severity index (MASI) score, was evaluated at weeks 0, 4, 8, 12, 16, 20, and 24. The patient assessment score by quartile rating scale was rated at weeks 12, 16, 20, and 24.ResultsFifty-nine (98.3%) subjects were included in the analysis. Each group showed significant change from baseline in MASI scores from week 4 to week 24. The MASI score in the PSNYL group showed the greatest reduction compared to the PSAL group (p = 0.016) and HQ group (p = 0.018). The PSAL group demonstrated comparable MASI improvement as the HQ group (p = 0.998). The PSNYL group had the highest patient assessment score, followed by the PSAL group and then the HQ group, although only the differences between PSNYL and HQ groups at weeks 12 and 16 were significant. Four patients (6.8%) experienced recurrence. Other unanticipated events were transient and subsided after 1 week to 6 months.ConclusionThe efficacy of non-fractional PSNYL was superior to that of non-fractional PSAL, which was not inferior to 2% HQ, thus non-fractional Picos providing an alternative for melasma patients with FSTs III-IV. The safety profiles of PSNYL, PSAL, and 2% HQ cream were similar.Clinical Trial Registrationhttps://www.chictr.org.cn/showprojen.aspx?proj=130994, ChiCTR2100050089.

Abstract
BACKGROUND The pathophysiology of melasma is multifactorial, resulting in treatment resistance and a high recurrence rate. Recent research suggests that focused ultrasound might treat melasma effectively. OBJECTIVES To investigate the efficacy and safety of superficial micro-focused ultrasound with visualization (MFU-V) for melasma in Asians. METHODS Patients (n = 20) with mixed melasma on both cheeks received 2 MFU-V treatments spaced 1 month apart. At monthly visits over 5 months, treatment efficacy and safety were evaluated. Standardized photographs were clinically assessed using the modified Melasma Area and Severity Index (mMASI), and 6-point grading scales for melasma lightening and area of involvement. Patients provided pain, global aesthetic improvement scale (GAIS), and satisfaction assessments. RESULTS In 40 cheeks, the mean mMASI score was significantly reduced from 13.2 at baseline to 2.4 at month 4, and 2.8 at month 5. Twenty-nine cheeks (72.5%) showed lightening of melasma at month 4 that persisted until month 5, with improvements up to 75% compared to baseline. Melasma area decreased overall, with sites containing >30% melasma involvement decreasing from 55% to 20% by month 5, and none with 70%-89% involvement. Melasma lightening and area improved visibly in 40% and 20% of cheeks, respectively, as early as 1 month after index MFU-V treatment. Improvements continued after the second treatment and persisted until study closure, correlating with patient GAIS and satisfaction scores. Procedure was well tolerated with only mild-to-moderate pain reported in 92.5% of treatments. CONCLUSION Superficial MFU-V is a safe and effective treatment for melasma.

Abstract
Doctors-in-training often receive an inadequate dermatology education. Furthermore, studies have highlighted the under-representation of skin of colour (SOC) in dermatological teaching, learning resources and research. Our image-based questionnaire, distributed to all internal medicine trainees in southwest England, highlighted knowledge gaps regarding SOC among training physicians. It is intrinsically more challenging for clinicians to confidently formulate dermatological diagnoses in SOC. In this review, we provide guidance for physicians to help make the diagnostic process more straightforward. First, we outline how skin colour is determined and classified. We discuss how inflammation presents in SOC, with the typical 'erythema' that physicians often associate with inflammation being a less prominent feature in darker skin tones. We then summarise nine important conditions that we believe physicians working in all specialties should be able to identify in patients with SOC, covering both conditions encountered on the medical take and conditions disproportionately affecting individuals with SOC. The population of the UK is rapidly diversifying; thus, as physicians, we have a professional duty to educate ourselves on dermatological conditions in SOC to provide the best quality of care for all our patients, regardless of their skin type.

Abstract
BACKGROUND/PURPOSE Melasma is a frequent photoexacerbated hyperpigmentary disorder, which can significantly impact on the quality of life. We sought to review the pathogenesis of melasma, and the role of photoprotection in the prevention and treatment of this disorder. METHODS We conducted a narrative review of the literature. We performed literature searches with PubMed from January 1990 to December 2021 using the keywords "melasma," "pathogenesis," "ultraviolet radiation," "visible light," "photoprotection," and "sunscreens." RESULTS The physiopathology of melasma includes a complex interaction between genetics, sex hormones, and sun exposure. Visible light, in particular high-energy visible light (HEVL), and long-wave UVA (UVA1) play a key role in melasma pathophysiology, and recent research suggests that melasma shares many features with photoaging disorders. Melasma disproportionately affects dark-skinned individuals. Some 30% to 50% of South Americans and Asians, among other ethnicities, can present with melasma. Dark-skinned patients take fewer photoprotective measures. Also, the majority of melasma patients do not adequately follow photoprotection recommendations, including the application of sunscreen. Intensive use of a broad-spectrum sunscreen can prevent melasma in high-risk individuals, can lessen melasma severity (associated or not with depigmenting agents), and can reduce relapses. CONCLUSIONS Due to the physiopathology of melasma, sunscreens should be broad-spectrum with high sun protection factor, and provide high protection against UVA1 and VL. Sunscreens should be cosmetically acceptable and leave no white residue. Tinted sunscreens are an excellent choice, as pigments can protect from HEVL and UVA1, and may provide camouflage, but they must offer colors that match the skin tone of each patient.

Microneedling with cutaneous delivery of topical agents for the treatment of melasma: A systematic review. J Cosmet Dermatol 2022; 21:5680-5695. [PMID: 35933690 DOI: 10.1111/jocd.15287] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 06/20/2022] [Accepted: 08/01/2022] [Indexed: 12/27/2022]
Abstract
BACKGROUND Melasma is an acquired hyperpigmentation disorder. Microneedling is an alternative treatment for melasma especially by improving penetration of pharmacological agents into the skin. OBJECTIVE The main objective of this review was to systematize and analyze available evidence on the efficacy and safety of microneedling alone or associated with topical agents in reducing skin stains and improving melasma-related quality of life in adult patients. METHODS Only randomized clinical trials were included. The following databases were consulted: MEDLINE, Embase, Cochrane, and the gray literature. The Cochrane risk-of-bias tool for randomized trials (RoB 2.0) was used to assess risk of bias. RESULTS The search retrieved 719 records and seven studies were included. A total of 368 participants (96.19% women) were evaluated. Two studies were split-face. Most of the studies evaluated microneedling associated with tranexamic acid. High risk of bias was presented by most studies, especially in the safety outcome. A significant decrease was observed in the MASI, mMASI, or hemi-MASI scores, regardless of the topical agents associated. Meta-analysis was not possible due to the heterogeneity of the studies. CONCLUSION Based on the results of this review, microneedling can, in association with topical agents or isolated, be used safely in the treatment of melasma in the clinical practice, obtaining results on reduction of stain severity and improvement of patients' quality of life.

Abstract
Melasma is a prevalent chronic relapsing pigmentary disorder that affects photoexposed areas, especially in women of childbearing age. Although there is currently no curative treatment available for melasma, this manuscript critically reviews the knowledge regarding photoprotection, topical and oral therapies, and procedures such as peelings, laser, and microneedling that represent the main strategies for control and prevention of this disease. As the pathogenesis of melasma is not entirely understood, there are prospects for the development of new therapeutic strategies that might act on the pathways that promote sustained pigmentation rather than merely decreasing melanin synthesis and removing melanin from the epidermis.
