Skin possesses the lifelong ability to renew itself, but as we age this process takes longer. Between the ages of 20 and 50 the rate of skin cell renewal gradually slows, and after the age of 50 it slows ever faster. The surface layer of the skin, the epidermis, becomes thinner and can store less water. In the dermis, or true skin, production of the collagen that supports and firms the skin declines. Menopause in women, during which the body reduces estrogen production, causes a further loss of firmness and elasticity. Environmental factors like UV radiation have a major impact, accelerating the decomposition of collagen and encouraging the formation of aggressive oxygen compounds that can damage skin cells from the membrane to the DNA. The subcutaneous layer of fat and loose connective tissue becomes thinner. At the same time, the supply of nutrients and energy to the skin deteriorates. It is therefore important to support the health of aging skin with a sufficient supply of micronutrients.
