Atrophic acne scars, the most common sequel of acne vulgaris are always a challenge to treat. Though many new modalities including chemical peels, soft tissue augmentation, lasers (non-ablative, ablative and fractional), subcision and radio frequency have been used. Microneedling stands out to be the cheapest, easiest and most efficacious modality in Indian skin type. We evaluated its effectiveness as the sole modality for treating atrophic acne scars. We found that there was an overall improvement in 91.8% patients by at least one grade. There were no serious complications except transient pain, erythema and oedema for 3-6 hours.
