Sunscreen Ingredients are Absorbed says FDA

For years public health officials, dermatologists and primary care physicians have been encouraging people to apply sunscreen before going out into the outdoors to reduce the risk of sunburn and skin cancers.  We are taught to apply it in advance of exposure by about 30 minutes and to reapply it every few hours especially if we are sweating and swimming.   Living in South Florida, sun exposure is a constant problem so we tend to wear long sleeve clothing with tight woven fabrics to reduce sun exposure.  My 15-month old grandson, visiting last weekend was smeared with sunscreen by his well-meaning parents before we went out to the children’s playground nearby.

These precautions seemed reasonable and sensible until an article appeared in JAMA Dermatology recently.  An article authored by M. Mata, PhD. evaluated the absorption of the chemical constituents of sunscreen after applying it as directed four times per day.  The article was accompanied by a supporting editorial from Robert M. Cliff M.D., a former commissioner in the FDA and now with Duke University School of Medicine and K. Shanika, M.D., PhD.

The study applied sunscreen four times a day to 24 subjects. Blood levels were drawn to assess absorption of the sunscreen products avobenzene, oxybenzone and octocrylene.  The results of the blood testing showed that the levels of these chemicals far exceeded the recommended dosages by multiples. The problem is that no one has evaluated these chemicals to see if at those doses it is safe or toxic causing illness?

The editorial accompanying the findings encourages the public to keep using sunscreen but cautions that the FDA and researchers must quickly find out if exposure to these levels is safe for us?  We do know that the chemical oxybenzone causes permanent bleaching and damage to coral reefs in the ocean from small amounts deposited by swimmers coated with sunscreen. The state of Hawaii has actually banned sunscreens containing oxybenzone to protect their coral reefs.

The fact that these chemicals have been approved and are strongly absorbed with no idea of the consequences is solely the result of elected officials wanting “small government” and reducing funding to the oversight organizations responsible for making sure what we use is not toxic.  It is a classic example of greed and profit over public safety.  The research on the safety of these chemicals must be funded and addressed soon. The American Academy of Pediatrics and Dermatology need to advise parents of youngsters whose minds and bodies are in the development and growth stages what is best to do for their children – sooner rather than later.
