This study found that grafting an autologous cultured epithelial sheet improved both scarring and skin texture in four patients with acne-associated scar contracture three months post-treatment, suggesting the technique might effectively treat difficult acne scars by metabolizing excess collagen.

January 2022 in “Oxidative Medicine and Cellular Longevity” Fibroblasts are crucial in scar formation and wound healing, with potential therapies aiming for scarless healing.
September 2023 in “International journal of biomedicine” This review evaluated current evidence on minoxidil's potential to treat scars and reported reduced collagen accumulation and fibrosis in various studies, suggesting its antifibrotic effects may benefit wound healing; however, direct studies on acne scars are yet to be conducted.
March 2026 in “Frontiers in Cell and Developmental Biology” This meta-analysis found that autologous cell-based therapies, especially stromal vascular fraction, significantly improved atrophic acne scars over control treatments, enhancing both clinical and patient-reported outcomes.
April 2026 in “Biomedical Research and Therapy” This study found that certain genetic variants, specifically CYB5R1 and IL1A, may be linked to different types of acne scarring, with CYB5R1 associated with atrophic scarring and IL1A with fibrotic scarring, indicating a potential polygenic nature of acne scarring.
