By the 1980's new sunless tanning formulations appeared on the market and refinements in the DHA manufacturing process creating products that produced a more natural looking color and better fading. Sunless tanning effects began to improve, but application methods were limited to hand applied lotions, creams, and spray pump bottles. These improvements seemed promising Consumer concerns surrounding damage associated with UV tanning options spurred further popularity of sunless tanning products as an alternative to UV tanning. Dozens of brands appeared on drugstore shelves, in numerous formulations. Today, Dihydroxyacetone appears to be the main active ingredient in the majority of sunless tanning skin care preparations. It is often used alone or combined with other tanning activities such as erythrulose in many different formulations.
