Abstract
The invention relates to an active ingredient combination containing erythrulose and a further reducing sugar with self-tanning properties, for example, dihydroxyacetone, which combination is used for artificially tanning the skin. Compared with compounds containing, for example, only dihydroxyacetone, said active ingredient combination and cosmetic compounds based thereon result in an even and longer-lasting colouring of the skin and prevent skin dehydration and uneven flaking.
