selftanning
Selftanning refers to cosmetic products designed to produce a tanned appearance without sun exposure. Most modern self-tanners rely on dihydroxyacetone (DHA), a sugar-derived compound that reacts with amino acids in the outermost skin layer (the stratum corneum) to create a brownish color. Some formulations also use erythrulose to slow development and deepen tone, producing longer-lasting results. The result is a cosmetic tan that typically appears within a few hours and lasts as the skin naturally exfoliates over several days.
Forms include lotions, mousses, gels, sprays, and wipes. Many products also contain bronzers for immediate color
Application tips include performing a patch test first, exfoliating before use, and applying in thin, even layers
Safety considerations: DHA is approved for external use in many regions, but products should not be applied
