What is it: palmitoyl tripeptide-3

This peptide, consisting of three amino acids, promotes collagen synthesis by mimicking the skin's natural processes. It is seen as an alternative to a collagen injection as it boosts the connective tissue growth factor necessary to produce collagen. Clinical studies have shown it can reduce the appearance of wrinkles and improve the skin's firmness and moisture level. It is used in the brand Dr LeWinn's Private Formula Ultra R4 range, Peter Thomas Roth's Age Defence Kit and was listed as one of the ingredients to keep an eye out for by Pierce Mattie public relations in the US.
