INTRODUCTION: Acanthosis Nigricans (AN) is an acquired disorder of keratinization. It presents as hyperpigmentation, velvety texture of skin that can involve any part of the body including the face. Different topical, systemic therapies, or physical therapies including laser have been explored. However, there are not many randomized controlled studies for the majority of therapy alternatives besides lifestyle modifications and weight reduction.
OBJECTIVES: The aim of this study was to compare the effectiveness of 15% trichloroacetic acid (TCA) and 35% glycolic acid (GA) peel for AN.
MATERIALS AND METHODS: Forty participants were included and randomized into two groups. In groups A and B, peeling with 15% TCA and 35% GA was done, respectively. The effectiveness of each peel was assessed using changes in the Acanthosis Nigricans Area and Severity Index Score (ANASI) and Physician Assessment Score. Statistical analysis included Wilcoxon-Mann-Whitney test, Friedman test, and generalized estimating equations.
RESULTS: The overall change in ANASI over time was compared in the two groups using the generalized estimating equations method. A significant difference was observed in the trend of ANASI over time between the two groups (P < 0.001). TCA peel group showed more change in ANASI as compared with GA peel group.
CONCLUSION: In our research, 15% TCA has a better efficacy when compared with 35% GA peel after three sessions of chemical peeling. We therefore recommend the use of 15% TCA peel in AN as a safe and effective treatment option. However, more comprehensive randomized control studies are required for supporting data.
