The sun emits three different types of ultraviolet light, UVA, UVB and UVC. Sunlight is important for us humans, we get vitamin D and the risk of osteoporosis decreases. But too much sun damages the skin and can even lead to skin cancer. When the sun's rays reach our skin, more melanin is produced in the epidermal pigment cells. Melanin protects us against the harmful UV rays. It is also the melanin that makes us browner. Too much sun can lead to insufficient melanin in our skin and the rays penetrate past the outer skin layer. Sun damage can appear much like a normal burn with burning, blisters and redness. Both UVA and UVB radiation cause damage to the cells that can lead to skin cancer. Therefore, it is important to protect yourself properly with SPF creams or to completely avoid the sun every once in a while to give the skin time to rest and heal. .
