How exactly does extensive sun exposure lead to skin damage and increase cancer risk. In which part of the skin is the sun doing the most damage. Is it in the epidermis or beneath ? I would like to know if UV-protective tattoos would be possible.

  • $\begingroup$ Roy, @theforestecologist is completely correct. Long story short, though, tattoos are a kind of skin damage, and may cause cancer. $\endgroup$ – anongoodnurse Mar 11 '19 at 5:35
