Self-tanning is a cosmetic process that allows individuals to achieve a sun-kissed glow without exposure to harmful ultraviolet (UV) rays. It typically involves the application of products containing dihydroxyacetone (DHA), a colorless sugar that reacts with the amino acids in the skin's outer layer, resulting in a temporary tan. Self-tanners come in various forms, including lotions, sprays, and wipes. The effects of self-tanning usually last for several days, gradually fading as the skin naturally exfoliates. To achieve the best results, it is recommended to exfoliate the skin before application and to follow the product's instructions carefully. Self-tanning is a popular choice for those looking to enhance their appearance safely.
