What it is
Decapeptide-4 is a synthetic peptide composed of a chain of ten amino acids, produced for use as a cosmetic skin-conditioning agent. Peptides of this type are incorporated at low concentrations and are marketed for supporting the look and feel of the skin. Its function in a formula is conditioning rather than structural or preservative.
Safety & warnings
Short synthetic peptides like decapeptide-4 are generally well tolerated, are used at very low levels, and are not recognized fragrance allergens or notably comedogenic. Sensitivity is uncommon but, as with any active, possible in reactive skin.
Origin & sourcing
Synthetic; manufactured by peptide synthesis rather than extracted from a natural source.
