Is this UV damage or just our reflecitivity to UV light?

  Melanin converts 99.9% of UV radiation into heat. Even the synthetic form as noted here https://www.ncbi.nlm.nih.gov/pubmed/15068035 https://www.ncbi.nlm.nih.gov/pubmed/15068035 The risk is poor nutrition, copper is needed for this skin pigment, which means competing with the demands placed by other parts of the body like collagen, (bones, skin, etc etc), blood cell production and more. Another problem is the skin is washed often, daily in most cases and exposed to chemicals which can become carcinogenic under the sun. Carcinogenic suncreams exist. So its a complicated picture, poorly understood. The photo's are useful for seeing the distribution of cells.
