Peptides help cell communication between collagen production and the epidermis.
What They Are:
As a result of age and environmental factors, smooth, young skin slowly becomes thinner and wrinkled over time. As collagen deteriorates, it produces certain peptides. A type of amino acid, peptides, which are naturally found in the skin, encourage the production of collagen and elastin to maintain healthy skin cells and give a plumper, more elastic look because they can dictate to skin cells how to repair themselves and function properly. The National Institute of Health shows that these peptides send a "message" to your skin that it has lost collagen and needs to generate more. When applied topically, your skin thinks that it's a collagen break down product and that your body needs to create new collagen.
How They Work:
Since the aging process causes a natural decline of peptides in the skin, synthetic versions found in serums and creams help strengthen collagen and elastin levels. The smaller the chain of peptides in a product, the more impact there is on collagen production because collagen is made of proteins that are bonded together with peptides. Using peptides on the skin makes the skin think it is experiencing a breakdown of collagen internally and therefore prompts the body to make more collagen. Peptides also work well with glycerin, which together helps bring moisture to the outer most layer of skin and lock it in.
What You'll Notice:
Over time the skin will start to look more plump, brighter, tighter and smoother, which is a direct result of the increase in collagen.
