These short chained amino acids have the ability to penetrate the upper layer of the skin (epidermis) and act as dispatchers capable of triggering specific functions, such as collagen support (1).

The Skin’s barrier

Types of peptides in skincare

Signal peptides

These are the collagen enhancers. They act as messengers helping to trigger the synthesis of collagen by fibroblasts.

Carrier peptides

These do what they say on the tin. They carry things, namely copper. Copper is associated with many incredible activities which include the formation of new blood vessels and wound healing.

As you many imagine, these are important attributes for firm, youthful skin.
