The EWG (Environmental Working Group) has determined that only about one-fourth of 800 different sunscreens marketed in the United States meet a 2012 standard established by the EWG for effectiveness and safety. Unfortunately, about one-fifth of the products analyzed contained vitamin A, known to accelerate the growth of tumors in skin exposed to the sun. Absolutely no active ingredients known to block UVA rays were found in 56 of the products.
The EWG provides a 2012 "Guide to Sunscreens" at http://breakingnews.ewg.org/2012sunscreen/. Additionally, "Sunscreens Exposed: Nine Surprising Truths" is offered. Common perceptions related to sunscreens are challenged with the following information:
1. Evidence is inconclusive related to sunscreens actually preventing skin cancers.
2. Some sunscreens contain ingredients that may actually increase the risk of melanoma.
3. High SPF sunscreens have not been proven more effective than other sunscreens.
4. Limited exposure to the sun contributes to vitamin D deficiencies.
5. Vitamin A, an ingredient in many sunscreens, increases the risk of some skin cancers.
6. Sunscreens can actually increase production of skin-damaging free radicals.
7. Most sunscreens contain either potential hormone disrupters or nano-minerals, both with potentially harmful effects.
8. Sunscreen ingredients approved in Europe, but not approved by the Food and Drug Administration (FDA), offer up to 5 times more UVA protection.
9. The role of FDA in evaluating and controlling the ingredients in sunscreens is not as effective as desired.
As nurses, we know sun exposure increases the risk of skin cancers. Often, we advise patients, friends, and families as to the need for sunscreen use. Evaluating this important evidence related to the most reliable and least harmful sunscreen products will benefit us, our students, our families, and our patients.
