UV IndexThis overview shows how dangerous UVA and UVB radiation is and how it can damage your skin.
Skin cancer is the most common cancer type. This is mainly because the cancer-causing UVA radiation cannot be perceived. For this reason, precautionary protection against both UVA and UVB radiation Is essential. UVA radiation does not only damage the epidermis but also the underlying so-called dermis.
UVB radiation, on the other hand, attacks the epidermis. The epidermis tries to protect herself with melanin. Thus, the skin appears tanned, which is in reality only a protective mechanism of the skin. If the skin is exposed to more UVB radiation than it can protect itself from, sunburn and, in the long term, skin cancer develop.
