Peptides are complex molecules derived from combining chains of amino acids (the body’s building blocks) that help to rebuild, revitalize and renew the appearance of damaged skin. Peptides belong to a group referred to as “cell communicating” ingredients. Peptides affect cell receptor sites and help to restore and maintain normal cellular function. When the skin is damaged for any reason, key proteins that promote skin and cell structure are destroyed. The body’s natural response is to release peptides which the skin interprets as a signal to produce more proteins, healing the damaged skin. Different peptides perform different functions in the skin and body. For example, Copper peptides promote collagen and elastin production while Palmitoyl Oligopeptides help smooth wrinkles and fill in fine lines on the skin.
