As we age, our skin changes in many ways. Our skin becomes papery thin and loses its elasticity. Fat cells below the skin shrink, and collagen and elastin fibres start to break down. These changes  lead to sagging skin, the formation of wrinkles, and a loss of that youthful glow. In addition, the production of new skin cells slows down, and the natural process of exfoliation becomes less efficient. Because of this, our dead skin cells accumulate on the skin’s surface, making it dull and dry. Exposure to UV rays can also cause premature aging by deteriorating collagen as well as increasing the risk of sun or age spots.
