Sun tanning describes the act of exposing the skin to ultraviolet radiation for the purpose of darkening skin colour. Tanning is a natural process, whereby the skin creates the brown-colored pigment called melanin to protect it against the harmful UV rays.
Firstly, the UVA-radiation generates oxidative stress, which in turn oxidises pre-existing melanin. This leads to rapid darkening of already existing melanin. Secondly, there is an increased production of melanin from UVB exposure leading to delayed tanning. It first becomes visible about 72 hours after exposure. Depending on a person’s genetic profile, some people can darken quickly and deeply whereas others do not darken much at all.
The ultraviolet frequencies responsible for tanning are often divided into the UVA and UVB ranges.
Although studies in humans remain untested, caffeine and caffeine sodium benzoate may be novel inhibitors of skin cancer.
