Ultraviolet rays can be of two types: Type A and B. Ultraviolet B produces burns and both cause cancer and wrinkles.

According to some studies, producers exposed to sunlight know if their substances filter the ultraviolet A. It is known that in the bottles of protective substances the protection factor appears. By analyzing products with protection factor 2 to 15, it has been detected that they are suitable for filtering ultraviolet B, but in general do not filter ultraviolet A.

Therefore, as a reader, to protect your skin from sunlight, it is not enough to rub it with the substances they sell in stores, which only protect us from a type of rays. However, it is soon expected that protective products will appear both A and B.
