Background: Atrophic acne scars cause psychological devastation and are difficult to treat. The demand for less invasive but highly effective treatment for scars is growing. Objective is to assess the efficacy of microneedling in the management of atrophic acne scars on the basis of morphology.

Methods: Fifty one patients with atrophic acne scars were selected. Each patient was evaluated for types of acne scars. Dermaroller was performed at 4 weeks interval for a total of 3 sessions. Evaluation of type of acne scar and photography were done pre-treatment and 6 months after the end of treatment. Patients own evaluation of improvement was assessed by patient perception scale.

Results: At the end of treatment, boxcar scars reduced by 47.06%, rolling scars reduced by 37.25% and 05.88% reduction was seen in ice pick scars. No treatment failure was seen. There was high level of patient satisfaction with patient perception scale of 8.15.

Conclusions: Dermaroller has shown good results in treating boxcar and rolling scars with little effect on ice pick scars.
