Abstract—Acne scarring is a kind of sequelae of acne, which is the scar left on the patient’s skin after acne occurs and the local inflammation is more serious and not controlled in time. It is a disfiguring skin disease that affects patients physically and mentally because it occurs on the face. The treatment of acne scarring has always been a popular and difficult clinical problem. Gold micro-needling is one of the commonly used treatments for acne scarring. Gold micro-needling can bring about some improvement in the extent of scarring, and is also useful for large areas of post-inflammatory erythema, however, it is less effective for icicle-like, compartmentalized, and elevated scarring. The fractional carbon dioxide laser can accurately grind raised, and irregular scarring, which can significantly improve the unevenness of the skin and make the lesions look more even. We report a case of gold micro-needling combined with fractional carbon dioxide laser for the treatment of severe post-acne scarring.
