Fractional ablative carbon dioxide laser resurfacing is a frontline treatment for acne scars. It creates multiple microscopic treatment zones to accelerate the collagen formation and the healing process of reepithelialization, according the principle of fractional photothermolysis. At present, the fractional CO2 laser with a wavelength of 10,600 nm is commonly used in the field of cosmetology and clinical therapies for various skin diseases, and it can effectively improve skin regeneration and scar formation. To obtain satisfactory results for patients with scars, repetitive fractional laser therapy is always required; however, this treatment could easily lead to complications such as erythema, edema, infection, and post-inflammatory hyperpigmentation. In addition, different types of acne scars may have different responses to laser, further limiting its widespread use. In recent studies both home and abroad, a new pattern of fractional laser combined with other therapies to improve acne scar has been recommended to guarantee the safety and effective of treatment. This article reviews the recent pertinent literatures and summarized the progression of ablative fractional CO2 laser combined with other therapies on acne scar.
