Proteins are the fundamental building blocks of skin.
Collagen is a protein comprised of long segments of amino acids arranged like a chain. When collagen breaks down, short segments of amino acids are formed. These are the tiny proteins and active molecules known as peptides.
Without peptides, skin doesn’t remain intact and the results is loss of firmness, appearance of wrinkles, texture changes, and skin that doesn’t bounce back as it once did.
What’s so fascinating about peptides is that abundant research has clearly shown they can help revitalize those building blocks and, in turn, help revitalize skin.
For people searching for the best ingredients skin-care manufacturers have to offer, peptides are at the top of the list. The skin contains natural peptides, which contribute to the structural strength of the skin and keep it plump and firm.
Pentapeptides (Matryxil), Oligopeptides and Copper Peptides work by stimulating the production of collagen and hyaluronic acid, two natural components of skin that people lose as they age. Neuropeptides (Argireline) act by affecting neurotransmitters in the skin. When this happens, nerve cells in the skin cease communicating and relax. The overall effect is that skin becomes smoother and wrinkles disappear.
Peter Thomas Roth Unwrinkle Serum, for example, contains a cocktail of all the above peptides which penetrate the skin to address common skin-care concerns, including wrinkles, from the inside out.
