Collagen
70% of the body's connective tissue in the dermis is made of collagen. Gerontologists have discovered that is where the aging process of the skin takes place. Young connective tissue is made up of soluble collagen whose molecules are disordered in relation to each other. As the skin ages, and is exposed to sunlight, chemicals (like makeup, coal tar dyes, etc., and various foods), the soluble collagen becomes "cross-linked," so the molecules are no longer displaced in relation to each other. Cross-linking makes the collagen insoluble and inflexible. As this happens, the connective tissues becomes strained, dry, wrinkled, and worn.
