Abstract

Background: Acne vulgaris is a chronic skin disease caused due to blockage and/or inflammation of pilosebaceous units in which lesions present as non-inflammatory, inflammatory or mixture of both. The inflammatory type, often results in distressing scars for which dermaroller therapy and fractional CO2 laser have shown to be effective treatment modalities. Material and Methods: This is a prospective, descriptive and hospital based study. Total of 140 cases were enrolled in study carried out for 1 year in the Department of Dermatology at tertiary health centre and medical college with subsequent follow up of up to six months. Patients with acne scars under the groupings of a score > 3 points on Global Acne Scarring Classification Scale were enrolled.Results: Out of 140 patients, (70 - dermaroller group, 70 - CO2 laser group) completed treatment and follow-up. Dermaroller therap results indicated that the baseline was 23.43±6.32 and reduced to 13.23±3.65 after the treatment. This difference was found to be statistically highly significant with p value as
