Be Careful of the Skin Photoaging Caused by Ultraviolet Rays

It seems that the ultraviolet ray and skin are always a couple of deadly foes. With the ozone sphere becoming thinner and thinner today, the ultraviolet ray has been the second killer to our skin. Being exposed to the sunlight for long periods will accelerate the speed of skin aging. Most people are misunderstanding that we just need to protect us from the strong sunlight in summer, however, ultraviolet rays never take rests all around the year. So we must apply sunscreen in all of the four seasons. To protect us from the ultraviolet rays well, we should understand its influence on the layers of our skin firstly.

       At first, we will learn something about the influence of ultraviolet ray on epidermis. Under the influence of ultraviolet ray, the melanophore in the basal layer will be activated to secret much more melanin which will darken the color of our skins. What is worse, it may also lead to the abnormal function of melanophore which will bring another trouble to you—the sunspots.

       The one follows epidermis is the dermis, of course. The corium layer is the one changes most prominently with the exposure to ultraviolet ray. Once being radiated by the UVB, the superficial dermis will produce plentiful free radical which is a kind of antioxidant that can accelerate the death of cells and the aging of skin. The deep dermis is mainly influenced by the UVA, with a performance of elastosis and breakage of azelon. Furthermore, after being radiated by ultraviolet rays, the fibroblast, melanophore and keratinocyte will lose their functions of self-rehabilitation.

       Finally, I will talk about the damage brought by the ultraviolet rays to the subcutaneous tissue. Given to the wavelength, only the UVA can reach to the subcutaneous tissue. The only effect of UVA on it is the increasing of temperature. But as people get old, the subcutaneous tissue will wither at the same time, which will lead to the appearance of wrinkles on our faces. So many beautician use Fractional laser machine to anti-aging, so that women can keep their youth forever.
