Stretch marks occur in the middle layer of our skin called the dermis. The dermis is the skin’s elastic layer, allowing our skin to stretch and snap back into shape. When this layer is continuously stretched over a long period of time, the collagen is damaged reducing the skins elasticity. The result is the scars we call stretch marks. Pregnancy, rapid weight gain or loss and puberty, are the usual causes of stretch marks. Almost half of all expectant women and many teenagers will acquire stretch marks. Stretch Mark Erase is easy to use. Gently massage the formula on to the affected area and wait for the results. The natural ingredients within this product reinforce the tissue and strengthens the skin thereby reducing the development of new scar tissue and repairing existing damaged layers.
