My guess would be DNA from salmon sperm since this is relatively cheap and easy to come by--we used in the lab when we needed "generic" DNA. I seriously doubt that DNA actually reflects the sunlight or that there are enough thymidine dinucleotides (little bits of DNA) in the whole DNA gamish to accomplish the DNA repair in human skin referred to above. this finding is probably from in vitro experiments where the thymidine is applied directly to cells in culture, not necessarily what happens when you put cream on your skin.
