Palmitoyl Pentapeptide-4
Introduction
Palmitoyl pentapeptide-4 is composed of five amino acids in a specific sequence: lysine-threonine-threonine-lysine-serine (KTTKS). The structure determines the performance, and the peptide sequence determines its ability to promote elastin production. In order to help the permeability of the pentapeptide, the palmitoyl lipophilic group was introduced to modify the structure.
Palmitoyl pentapeptide-4 is a small, highly specific bioactive peptide known as micro-collagen. At the same time, as a signal peptide, palmitoyl pentapeptide-4 can clinically improve wrinkles and fine lines caused by photoaging and natural aging by issuing instructions and transmitting signals to remind the body to form new collagen, increase the synthesis of skin elastin, hyaluronic acid, glycosaminoglycans and fibronectin, and make the skin younger and more elastic. After connecting with fat-soluble palmitic acid, its skin penetration is enhanced. Palmitoyl pentapeptide-4 can also accelerate the expression of wound repair genes.
