Signal peptide like peptide can promote the synthesis of matrix protein, especially collagen, and increase the elasticity at the same time. These peptides promote collagen synthesis by increasing the activity of stromal cells, making the skin look

To be more flexible and young. Similar to traditional anti wrinkle raw materials, such as derivatives of vitamin C and vitamin A, but the ability to promote collagen production is much better than that of vitamin C and vitamin A (retinol). The research of p&g company shows that palmitoyl pentapeptide-3 can promote the production of collagen (types I, II and IV) and other extracellular matrix proteins (including elastin and fibronectin).

The role of palmitoyl oligopeptide (palmitoyl Tripeptide-1) is basically the same, which is also the reason why palmitoyl oligopeptide is widely used. The common palmitoyl pentapeptide-3, palmitoyl Tripeptide-1, palmitoyl hexapeptide, palmitoyl tripeptide-5, hexapeptide-9 and myristoyl pentapeptide-11 in the market are all signal peptides
