REGULATION OF MAMMALIAN KERATINOUS TISSUE USING N-ACYL AMINO ACID COMPOSITONS

摘要

Skin care compositions containing N-acyl amino acid, particularly N-acyl derivatives of Phenylalanine or Tyrosine, their isomers, or their salts; at least one other skin care active selected from sugar amines, vitamin B3, retinoids, peptides, dialkanoyl hydroxyproline, hexamidine, salicylic acid, and phytosterol; and a dermatologically acceptable carrier for the N-acyl amino acid and the skin care active. The invention further relates to methods for regulating the condition of mammalian keratinous tissue wherein the methods each comprise the step of topically applying to the keratinous tissue of a mammal needing such treatment, a safe and effective amount of the skin care composition of the invention.
