F. A. Q.
DHA is an acronym for Dihydroxyacetone. DHA is the active ingredient found in all sunless tanning products. It is a simple carbohydrate that is primarily used as an ingredient in sunless tanning products. It is often derived from plant sources such as sugar beets and sugar cane, and by the fermentation of glycerin. DHA does not make the skin cells darker in pigmentation, but rather reacts with the proteins and amino acids found in the top layer of your skin to create a darkening effect.
