What Is Erythrulose?

Substance chemically similar to the self-tanning agent dihydroxyacetone. Depending on your skin color, there can be a difference in the color with erythrulose. Erythrulose needs about two to three days for the skin to show a color change, while dihydroxyacetone completely changes the color of skin within two to six hours. For this reason, most products that contain erythrulose also contain dihydroxyacetone.
