Studies have shown that copper peptide promotes the production of collagen and elastin in your skin. It also acts as an antioxidant and promotes production of glycosaminoglycans (such as hyaluronic acid).
Studies have also shown that copper-dependent enzymes help firm, smooth, and soften the skin quicker than most other anti-aging skin care products. In addition, copper peptides have been shown to remove damaged collagen and elastin from the skin and scar tissue.
Be wary of these claims, however, since the effects on your skin may be far less than is seen in laboratory testing.
Alpha-lipoic acid diminishes fine lines, gives skin a healthy glow, and boosts levels of other antioxidants, such as vitamin C.
Alpha-lipoic acid can enter all parts of a skin cell. Due to this quality, it is believed that alpha-lipoic acid can provide more protection than other antioxidants against so-called free radicals that can damage skin.
