Enhancing cosmetic outcomes by combining superficial glycolic acid (alpha-hydroxy acid) peels with nonablative lasers, intense pulsed light, and trichloroacetic acid peels.

Nonablative lasers, intense pulsed light (IPL), and trichloroacetic acid (TCA) peels are cosmetic rejuvenation techniques used to remodel skin and provide improved skin texture, firmness, and even pigmentation. Glycolic acid is an α-hydroxy acid that can be used as a topical skin peel to provide important complementary benefits to nonablative lasers, IPL, and TCA peels. Superficial glycolic acid peels provide both epidermal and dermal antiaging benefits, can be used to smooth the stratum corneum to reduce light scattering, and can enable the use of lower concentrations of TCA during a peel procedure. When used with these procedures, glycolic acid peels can enhance skin benefits and perceived patient outcomes. Methods of combining nonablative lasers, IPL, and TCA peels with glycolic acid peels were discussed at a dermatologist roundtable event and are summarized in this article.
