|  |  | Why the skin ages
Young skin is smooth, plump and supported from the inside by a matrix of collagen and elastin that gives the skin its firmness and elasticity. Young skin also has an abundance of growth factors that signal the fibroblast cells to produce and maintain this matrix. But growth factors become less plentiful with age, causing the fibroblasts to get sluggish. As the production of collagen- and elastin-producing fibroblasts slow down, enzymes in the skin begin to destroy the supportive matrix faster than it can be replenished, and that's when fine lines , wrinkles, dullness and other signs of aging become apparent.
