Acne scars have high prevalence, significant impact on quality of life and are a therapeutic challenge for dermatologists. Previous studies have shown promising results for the treatment of acne scars with non-ablative fractional laser and microneedling, however there are no studies comparing the these techniques. Therefore, the objective of this study is to compare the effectiveness of treatment of atrophic acne scars on the face with non-ablative fractional erbium laser and microneedling.
