Abstract
A cosmetic skin-renewal stimulating composition suitable for daily use by consumers and providing anti-aging benefits with control of delayed irritation. The invention adds small quantities of a naturally occurring small-molecule, biologically active, aliphatic aminodiol lipid, for example sphingosine, to cosmetics incorporating a skin-renewal stimulating acid, for example lactic, hydroxybenzoic or retinoic acid, to provide control of deferred hyperproliferative allergenicity induced by the skin-renewal stimulating acid. Comparative data show a beneficial control of long-term irritation induced by several weeks of daily use of a variety of skin-renewal stimulating acids. The novel activity is displayed by sphingosine alone among several classes of biologically active skin lipids, in a selective and surprising manner. The results suggest applicability of the invention to wider classes of cell-proliferation agents for the control of deferred hyperproliferative allergenicity.
