  • COMBINATION OF ERYTHRULOSE AND A REDUCING SUGAR WITH SELF-TANNING PROPERTIES

    Abstract: The invention relates to an active ingredient combination containing erythrulose and a further reducing sugar with self-browning 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.
