Abstract

Abstract : BACKGROUND: Acne scars are a permanent disfiguring sequel of acne. OBJECTIVE: To compare the efficacy of microneedling with 15% trichloroacetic acid (TCA) peel versus microneedling with 25% pyruvic acid peel in the management of postacne scars. MATERIAL AND METHODS: Thirty patients with atrophic acne scars were randomized into 2 groups receiving microneedling on both sides of the face at 0, 6, and 12 weeks and 15% TCA on one side and 25% pyruvic acid on other side at 3, 9, and 15 weeks. Acne scar scoring performed using the Echelle D'Evaluation Clinique des Cicatrices D'Acne (ECCA) and visual analogue scales by patient and physician were used to grade improvement at all visits and at 21 weeks. RESULTS: The mean ECCA score on the TCA side declined from 151.17 ± 26.90 to 138.83 ± 30.56 and on the pyruvic side declined from 151.83 ± 27.53 to 141.33 ± 28.92 after 21 weeks (statistically significant: p -value <.05). Comparing the ECCA on the TCA and pyruvic sides at 21 weeks was not significant. VAS showed moderate-to-marked improvement after 3 months in both groups. CONCLUSION: In our study, the combination modality showed early reduction in rolling and boxcar compared with icepick scars. These peels led to improvement in overall texture of the skin, hence more patient satisfaction. On comparing ECCA, a significant difference was not observed.
