INTRODUCTION: Acne scars, stemming from collagen irregularities in acne vulgaris, pose psychosocial challenges. This study evaluates the efficacy and safety of 1064 nm Q-switched Nd:YAG laser (QSNL) and microneedling for atrophic acne scars. METHODS: A retrospective study at Ege University included 30 patients with moderate-to-severe atrophic facial acne scars. Patients received three monthly sessions of either QSNL or microneedling from September 2020 to April 2022. Outcome measures included scar size reduction, Goodman and Baron scales (GBQN), Patient Healing Assessments (PHA), Investigator's Global Assessments (IGA), Dermatology Life Quality Index (DLQI), and side effects, evaluated at baseline, 1 month, and 4 months. RESULTS: Scar sizes decreased by 52.63% and 57.14% post-laser, and 62.99% and 69.23% post-microneedling at 1 and 4 months. GBQN scores declined by 28.46% and 38.05% for laser, and 27.18% and 34.38% for microneedling. IGA and PHA improvements were significant, with DLQI scores decreased by 58.28% and 50% for laser and microneedling, respectively. Both treatments proved effective with minimal side effects, with microneedling causing mild erythema and no persistent dyspigmentation or infection. CONCLUSION: QSNL and microneedling effectively and safely treat atrophic acne scars, improving scar dimensions, quality of life, and satisfaction. Long-term collagen remodeling highlights the importance of follow-up.
