The Spray Tan consist mainly of water, DHA, and Aloe Vera. DHA (dihydroxyacetone ) is a simple non-toxic sugar. DHA is the active ingredient that gives your skin a golden brown color. It is often derived from plant sources such as sugar beets and sugar cane. When applied to the skin, DHA penetrates only the outermost layer of skin, and does not absorb into the body or bloodstream.
