Direct DNA damage is confined to areas that can be reached by UV-B light. In contrast free radicals can travel through the body and affect other areas - possibly even inner organs. The traveling nature of the indirect DNA damage can be seen in the fact that the malignant melanoma can occur in places that are not directly illuminated by the sun - this is in contrast to basal-cell carcinoma and squamous cell carcinoma which only appear on directly illuminated locations of the body.[citations needed]

Indirect DNA damage is reduced by the topical sunscreen that stays on the surface of the skin. However, if sunscreen penetrates the epidermal barrier and gets into contact with living tissue, the indirect DNA damage is amplified many times, which causes damage to living tissue even at very low concentrations (10 μmol/L).[6][7][4][5]
