Signal peptides can promote the synthesis of matrix proteins, especially collagen, and at the same time can increase elasticity. These peptides promote collagen synthesis by increasing the activity of stromal cells, making the skin look more elastic and youthful. Similar to traditional anti-wrinkle ingredients, such as vitamin C and derivatives of vitamin A, but the ability to promote collagen production is far better than vitamin C and vitamin A (retinol), P&G research shows that palmitoyl pentapeptide-3 can Promote the production of collagen (type I, II and IV) and other extracellular matrix proteins (including elastin and fibronectin, etc.). Palmitoyl oligopeptides (palmitoyl tripeptide-1) do basically the same thing, which is why palmitoyl oligopeptides are commonly used.

Palmitoyl pentapeptide-3, palmitoyl tripeptide-1, palmitoyl hexapeptide, palmitoyl tripeptide-5, hexapeptide-9 and myristoyl pentapeptide-11, which are commonly available in the market, are all signal peptides .
