Do anti-wrinkle creams really work? (part 2 of 2)
Vitamin C is essential for the production of collagen. It also encourages the renewal of skin cells and is an antioxidant, which means that it mops up skin damaging free radicals. Vitamin C is a very unstable vitamin that is broken down by light and does not penetrate the skin readily, so cosmetic companies have had great difficulty making a skin preparation containing it. They seem to have cracked the problem, and skin preparations containing vitamin C are now available.
Copper peptides. Copper is a trace element found in every cell. In products applied to the skin, it’s combined with small protein fragments called peptides. Copper peptides enhance wound healing. They also stimulate production of collagen and may enhance the action of antioxidants. It is not known if they reduce wrinkles.
Collagen. Collagen creams work only on the skins surface. A moisturizer with or without collagen, cannot penetrate the skin and is not designed to be absorbed. No moisturizer can undo the cumulative effect of collagen loss. Creams primarily slow the rate of water loss from the skin and help keep the skin supple.
