STUDY BACKGROUND Post acne scars are always a challenge to treat, especially the ones which are deep seated. There are many treatment options like laser resurfacing, dermabrasion, microdermabrasion and non-ablative laser resurfacing but with considerable morbidity and interference with the daily activities of the patient in the post-treatment period. Microneedling or dermaroller therapy is one of the new treatment options in the management of acne scars with satisfactory improvement and no significant side effect. The aim of the present study is to perform an objective evaluation the efficacy of microneedling in the treatment of atrophic acne scars. MATERIALS AND METHODS Thirty patients of skin type III-V having atrophic facial acne scars presenting to our dermatology OPD. were received multiple sittings of microneedling (dermaroller) treatment with an interval of 6 weeks between each session. Goodman & Baron’s acne scar grading system was used for assessment of their scars and was evaluated clinically by serial photography at the start as well as at two months after the conclusion of the treatment. Patients on anticoagulant therapy, of keloidal tendency, with bleeding disorders, vitiligo patients, pregnant and lactating mothers and patients with active acne lesions were excluded from the study. The duration of this study was for ten months-from January 2014 to October 2014. RESULTS Any change in the grading of scars after the end of treatment and follow-up period was noted down. The efficacy and improvement of dermaroller treatment was assessed by Goodman and Baron’s Global Acne Scarring System. Out of 30 patients, 26(80.64%) patients achieved a reduction in the severity of their scarring by one or two grades. Quantitative assessment showed that 13.3% of patients had minimal, 16.6% had good and 70% showed very good improvement. Adverse effects were limited to transient pain, erythema and edema. CONCLUSION Microneedling therapy seems to be simple and efficacious for the management of atrophic facial acne scars
