Microneedling by dermapen and glycolic acid peel for the treatment of acne scars: Comparative study.

BACKGROUND

Many methods have been performed to achieve a satisfying outcome in acne scars but some of them were high cost and also were associated with low results and some complications.

OBJECTIVES

To evaluate and compare the efficacy and safety therapy of glycolic acid (GA) peel, microneedling with dermapen and a combination of both procedures in treatment of atrophic acne scars.

PATENTS AND

METHODS

This study was conducted on 30 patients suffering from acne scars. They were randomly assigned into three groups, each group included 10 patients; group I was treated with GA peel, group II treated was with microneedling. Group III received a combination of both procedures. All patients received six sessions with 2-week intervals. The clinical assessment was based on the qualitative global scar grading system before and after treatment, quartile grading scale, and degree of patient satisfaction.

RESULTS

There was a statistically significant decrease in acne scars grade after treatment among the studied groups (P = 0.04) but it was higher in group III. There was improvement in boxcar, ice pick, and rolling scars in all groups, respectively (P = 0.03, P = 0.04, P = 0.04). Patients' satisfaction was higher in group III (P = 0.04).

CONCLUSION

The combination of dermapen and GA peel is more effective than monotherapy.
