Background: Acne scarring represents a frequent and distressing complication of acne vulgaris, often leading to significant psychosocial burden and reduced quality of life. Atrophic acne scars, including ice-pick, boxcar, and rolling scars, arise from dermal matrix destruction and abnormal wound healing following inflammatory acne lesions. Various therapeutic modalities have been developed to improve scar appearance, including chemical peels, laser resurfacing, subcision, dermal fillers, and microneedling. Among these, microneedling has gained substantial attention due to its minimally invasive nature, favorable safety profile, and effectiveness across different skin phototypes. In recent years, the combination of microneedling with topical or transdermal delivery of hyaluronic acid has emerged as a promising strategy to enhance clinical outcomes in acne scar management.
