SpecialChem / Nick Morante – Jan 13, 2010

There are chemical materials that makeup the structure and function of the skin. But as the body ages, and normal biological processes slow down, the normal aging process takes place and these materials that were once abundant in the skin are now at lower levels. What cosmetic formulators try to do is introduce these same materials that occur in the skin as part of personal care products in order to replenish these missing materials. These are used as anti-aging ingredients to reduce or reverse the visible signs of aging. Some of the ingredients that are used in personal care products today are ceramides, hyaluronic acid, glycolipids, polysaccharides, essential fatty acids, amino acids, proteins, antioxidants and vitamins. These ingredients reduce transepidermal water loss, provide moisturization, increase skin elasticity, promote cell turnover, protect the skin from environmental damage and keep the skin smooth and younger looking.This is the second part of our article on basic skin biology. In Part 2 we will discuss the most common ingredients that we can add to cosmetic products to replace the reduced amount of normal material found in the skin to fight the visible signs of aging...
