Dihydroxyacetone (DHA), the active ingredient in most self-tanners, usually starts to work within 2 to 4 hours after application. However, it can take up to 24 hours for the full effect to develop. For best results, avoid bathing, swimming, or sweating during this time to allow the DHA to fully react with the skin.
