EFFECTIVENESS OF MILD CHEMICAL PEELS IN THE MANAGEMENT OF POST-ACNE AND POST-INFLAMMATORY HYPERPIGMENTATION

Abstract

Introduction:  Acne vulgaris is a common dermatological condition affecting young adults and is frequently associated with hyperpigmentation, enlarged pores, and altered skin texture. Chemical peels are widely used as a safe and effective treatment option for these concerns. Objective:  To compare the efficacy and safety of glycolic acid, lactic acid, and mandelic acid peels in the management of acne and associated skin conditions. Methodology:  This comparative interventional study was conducted on 60 patients aged 20–35 years. Participants were divided into three equal groups receiving glycolic acid, lactic acid, and mandelic acid peels. Clinical parameters including acne severity, hyperpigmentation, skin texture, pore size, and oiliness were assessed before and after treatment using a standardized grading scale. Side effects such as redness, burning, dryness, peeling, and post-inflammatory hyperpigmentation were also recorded. Data were analyzed using IBM SPSS Statistics version 32.0, and appropriate statistical tests were applied. Result:  All three chemical peels demonstrated noticeable improvement in acne severity and associated skin parameters. Among the treatments, lactic acid showed comparatively better clinical outcomes, followed by mandelic acid, while glycolic acid showed relatively lesser improvement. The procedures were well tolerated, with only mild and transient side effects observed. Overall patient satisfaction was found to be high. Conclusion:   Chemical peels are an effective and safe modality for the treatment of acne and related skin concerns. Lactic acid appears to be more effective compared to mandelic and glycolic acid peels, with minimal side effects and good patient acceptance.
