1,3-Dihydroxyacetone

1,3-Dihydroxyacetone (DHA) is a self-tanning agent used in cosmetics designed to provide a tanned appearance without the need for sun exposure.

Dihydroxyacetone powder is used as a major ingredient in most sunless tanning products. It can be used alone for the desired effect or combined with other tanning additives such as Erythrulose for a more specific effect. Regardless of the product used, the user’s skin usually begins to change color within 2-4 hours. Over the next 24-72 hours, the color will get darker.
