Natural peptides in the skin
Peptides are naturally present in the skin, derived from the enzymatic breakdown products of structural proteins in the epidermis and dermis. They can regulate hormone activity, enhance or inhibit immune responses, transmit signals between cells, and repair scar wounds.
Simply put, peptides can be understood as information transmitters between skin cells.
