| dihydroxyacetone |
(DHA): The FDA approved active ingredient in topical self-tanning products. This is a harmless skin dye that reacts with an amino acid in the skin or sweat to produce a temporary tan that flakes off as you shed skin. The higher the concentration, the more orange the tan will appear. Does not offer any skin protection against the sun.
