Acne scarring is a common disfiguring sequela of acne vulgaris which can lead to serious psychosocial problems and have a negative effect on patients’ quality of life. Although a variety of approaches can be used to treat atrophic acne scars, disadvantages such as long‐healing time, dyspigmentation, infections, and prolonged erythema make these treatments unsatisfactory especially for Asians. Fractional micro‐plasma radio‐frequency is a novel technology that produces minor ablation to the epidermis to promote rapid re‐epithelialization, while the radio‐frequency evoked thermal effect can stimulate regeneration and remodeling of dermal fibroblasts.
