A 2004 study done by Harvard University scientists discovered that the pills dramatically decreased redness in the skin of human subjects.6 Another clinical test found that after oral administration of Polypodium leucotomos, there was increased photoprotection of immune Langerhans cells.7 The science behind this new antioxidant supplement is pretty solid, and, if taken correctly, it could help prevent sun damage.

"We found that patients with skin cancer who practice very good photoprotection [sun protection] have lower vitamin D levels," said Dr. Jean Tang, lead author of the study.

"Most likely," said Tang, "the fact that skin cancer patients avoid sunlight is probably the number-one contribution to why they have low vitamin D levels, because the major difference between the two groups was that the skin cancer patients were practicing good photoprotection."
