The Causes And Effects Of Collagen Loss By NewBeauty Staff | July 12, 2010 Collagen is a tough, almost rubbery protein that's created by cells called fibroblasts. Packed together as bundles, fibrous bands of collagen serve as the main support system of the dermis, the deepest layer of skin. Collagen gives skin its strength, and it makes skin firm and flexible with the help of elastin. Collagen is essential for young-looking skin because it gives structure to its cells. When collagen levels becomes depleted, the skin has little internal support, causing it to sag and contributing to wrinkles.
