In the interest of science, do your own skins! First, narrow your candidates to ones with different ingredients. Include untreated skin as a control. Keep detailed records. Mark the skin or build a mask so you control what skin is treated. Take raw image digital photographs under identical lighting conditions. Apply each according to its instructions. One of you should design your sun exposure so it's reasonable for untreated skin: start small and gradually increase exposure each day. In my personal opinion, that will be the healthiest. The other might try for an intentional sunburn, but only on small skin areas.
Most animals are exposed to the sun all the time, which should give you a clue that exposure to sunlight isn't the deadly hazard it's portrayed to be. If they use tanning lotion, their skin provides it.

pig skin is used when cadaver skin isnt available fo testing. Neither may be available to you on short notice. I you are just testing the UV blocking effect, I'd think about using chicken parts..like a family size package of fresh legs...they're cheap, and still have the skin on them....treat each one, then let them bake in sun...then take a digital picture of the subjects for a record....
