Comparative study of fractional Co2 laser with salicylic–mandelic acid peel v/s dermaroller with salicylic–mandelic acid peel for treatment of post acne atrophic scars

Abstract

Introduction: Scarring in acne is a major concern cosmetically disfiguring the face , so treatment of acne scar is challenging. Methodology: Aims and Objectives: 1. To compare the effectiveness of fractional Co2 laser with salicylic mandelic acid (SM) peel versus Dermaroller with salicylic mandelic acid (SM) peel in treatment of post acne atrophic scars. 2. To evaluate complications and demographic details. Method: 30 patients were recruited and randomly divided into 2 groups. Each group contains 15 patients. In GROUP 1: fractional Co2 laser (Fr.Co2) done followed by SM peel 15 days later for 6 settings each. GROUP 2: Microneedling with dermaroller followed by SM peel 15 days laterfor 6 settings each. Photographs were taken pretreatment & at each visit and the improvement was graded using global assessment score by both treating physician and the patient. Results were evaluated and statistical analysis done using SPSS version 20. Results: On comparison, both the groups showed improvement in scars, but the percentage of scar grade improvement was more in group B (38.89%) than group A (33.89%). Conclusion: This study concludes both treatment modalities are effective but more scar grade improvement was seen with DERMAROLLER+SMP (38.89%) than FCO2+SMP (33.89%) and shows a future treatment for acne scar patients.
