Ultraviolet rays are said to be the biggest cause of accelerating skin aging. Skin care which we do everyday also has an important role of "protecting skin from ultraviolet rays". Even if you know that "ultraviolet light is the enemy of your skin", then it is actually fewer people who have proper ultraviolet care. Ultraviolet rays may not be visible, and the reason may be that the influence does not immediately appear on the skin. The sunscreen protects the skin from this ultraviolet ray.
