What Doctors Don't Tell YouHigh levels of oxybenzone used extensively in sun products with especially high sun protection factors (SPF) can be absorbed into the body and subsequently excreted in the urine, according to research.
Because manufacturers recommend that sunscreen be reapplied frequently, the amount absorbed into the body over time can be significant.
Few studies have been done on the toxic effects of oxybenzone, and the authors say better research should be done on the subject. They further suggest that sunscreens should not be relied upon as the sole method of sun protection and should not be applied on large areas of the body repeatedly over an extended period of time (Lancet, 1997; 350: 863-4).
