Photoaging and Nonablative Photorejuvenation in Ethnic Skin

Background:. Advances in nonablative skin rejuvenation technologies have sparked a renewed interest in the cosmetic treatment of aging skin. More options exist now than ever before for reversing cutaneous changes caused by long‐term exposure to sunlight. Although Caucasian skin is more prone to ultraviolet light injury, ethnic skin (typically classified as types IV to VI) also exhibits characteristic photoaging changes. Widespread belief that inevitable or irreversible textural changes or dyspigmentation occurs following laser‐ or light‐based treatments has been challenged in recent years by new classes of devices capable of protecting the epidermis from injury during treatment. Demographic changes in the US population favor an increasing trend of older, ethnically diverse patients requesting treatment to recapture a youthful appearance. Objective. The purpose of this article is to review the recent literature regarding clinical recognition and treatment of photoaging changes in ethnic skin. This article provides a basis for classification of current and future nonablative technologies with regard to the safety and efficacy of treatment in ethnic skin. Conclusions. Nonablative technologies have emerged to meet the public demand for no‐downtime treatment of aging skin. As these technologies continue to evolve and improve, physicians are challenged to define realistic goals, expectations, and limitations for treatment. Whenever possible, ongoing and future studies should attempt to address treatment in ethnic skin types. Photoaging changes in ethnic skin can be recognized and successfully treated with nonablative technology with minimal risk and downtime.
