There are dozens of products on the market which will, according to the manufacturer's claims, nourish your skin. These products contain such varied ingredients asprotein, vitamins, collagen, hormones and just about anything else that sounds efficacious, are said to feed the skin and to add 'specially formulated foods' to the skin's natural diet.Collagen is probably one of the commonest ingredients, but an awful lot of nonsense is talked about this substance. It is perfectly true that collagen is a normal constituent of good, healthy skin and that without collagen the skin looks wrinkled and aged, but putting replacement collagen into a skin cream isn't likely to do much good at all. The problem is that however much collagen a cream contains there isn't evidence to prove that it will be absorbed by your skin. The same is true of elastin, avocado and all the other ingredients so much loved by those who prepare nourishing creams.
The bald truth is that the inner layers of the skin derive their nourishment from their blood supply, and the cells on the outer surface of the skin are dead. The skin does not absorb food from special creams. If you could absorb substances into your skin, then you'd be full of soap! Nourishing creams are a waste of money. The only thing they nourish is the manufacturers' bank balances.
