When you reach your 40s, some of the collagen fibers are damaged permanently leaving no chance for regeneration. Hence, the skin cell bonding becomes weaker. Your skin becomes less elastic and this make the lines and wrinkles on the skin. At this age, the priority is retaining the moisture in your skin, which will keep it soft and flexible. Your skin needs nourishment. You need facial products that nourish and moisturize your skin. Regular skincare treatment using natural products is good. And do not forget to exfoliate, because dead skins show a higher tendency to deposit on your skin making it look dull and destroying your natural complexion. Choose anti- aging products that are rich in hyaluronic acid (HA) which is great for its water-retaining properties. The product contains vitamin A or retinol due to its ability to stimulate collagen for a plumper skin effect, increased cell turnover for a smoother. If you choose product with Vitamin A, make sure you wear a good sunscreen. By increasing cell turnover, those on the surface of the skin are younger and therefore are susceptible to sun damage.
