Executive Summary
TOPICAL pTpT MAY PROVIDE PROTECTIVE TAN WITHOUT UV EXPOSURE, Boston University School of Medicine researchers Mark Eller et al. suggest in scientific correspondence published in the Dec. 1 issue of Nature. The study, "DNA damage and melanogenesis," postulates that "topical application of pTpT [dipyrimidine dithymidylic acid] or other dinucleotides or DNA fragments may provide a protective tan for human skin without prior exposure to damaging ultraviolet irradiation."
