What Is Palmitoyl Dipeptide-5 Diaminohydroxybutyrate?
Palmitoyl dipeptide-5 diaminohydroxybutyrate is a synthetic peptide creation from a reaction of the fatty acid palmitic and the amino acid derivative diaminohydroxybutyric acid with dipeptide-5. In cosmetics, its primary function is as a skin conditioning ingredient.
This peptide is featured as part of an ingredient blend called SYN®-TACKS CB that also includes water, glycerin, and palmitoyl dipeptide-5 diaminobutyroyl hydroxythreonine. Manufacturers of the blend claim it improves skin elasticity, firmness, and suppleness by strengthening the junction between the dermis and the epidermis.
In peptide blends, palmitoyl dipeptide-5 diaminohydroxybutyrate is generally used in amounts between 1-3%.
