Collagen accounts for 25% of the total amount of proteins in the body, the most plentiful of all bodily proteins. It is fibrous and holds together and supports other body tissues. Collagen is present in skin, tendons, cartilage, bone, and teeth. It is sold as a dietary supplement to help with joint mobility. Along with elastin, collagen gives body tissues their form and strength and flexibility. These two substances work together in lungs, tendons, bones, and blood vessels. Another protein in the skin, keratin, works with collagen and elastin to give skin resilience. As we get older, collagen degrades and leads to wrinkles. Therefore, to fight visible effects of aging, collagen is very helpful. Unfortunately, collagen is too large a molecule to be absorbed through the skin. Some anti-aging science is aimed at stimulating production of collagen in skin cells. Collagen degradation is worse in sun damaged skin. Loss of collagen makes people look older and tired. There are several injectible collagen products that can replace some of the collagen lost through aging and sun exposure. Zyderm and Zyplast are injectible collagen products made from highly purified cow collagen. They are used to produce better lip definition, and to fill out fine lines and acne scars. The effects last three to six months. Before using either of these, clients have to have a skin test to determine if there is an allergic response to Zyderm or Zyplast. Cosmoderm and Cosmoplast are made from purified human collagen. They do not require an allergy skin test before treatment. Results last two or three months. Evolence is one of the newer dermal fillers. It is derived from pig collagen and is injected into the underlying skin layers to correct medium to deep facial wrinkles. There is some evidence that Evolence causes less temporary bruising and swelling than other dermal fillers. It also appears to last longer than other fillers — up to 12 months in some cases.
