EWG Recommends Only 8% Of Sunscreens; What's That About Vitamin A?
Many in the US population now should legitimately fear the effects of the sun on their skin, regardless of age. However, most of the aging population find themselves in dermatologists' offices with 'things' being burned or peeled off in one way or another nowadays. And if you think that tanning salons might prove an alternative, think again.
The fourth annual Sunscreen Guide by Environmental Working Group (EWG) gives low marks to the current crop of sunscreen products, with a few notable exceptions. EWG researchers recommend only 39, or 8 percent, of 500 beach and sport sunscreens on the market this season.
The reason? A surge in exaggerated SPF claims (SPFs greater than 50) and recent developments in understanding the possible hazards of some sunscreen ingredients, in particular, new government data linking a form of vitamin A used in sunscreens to accelerated growth of skin tumors and lesions.
Industry's lackluster performance and the federal Food and Drug Administration's (FDA) failure to issue regulations for sunscreens lead EWG to warn consumers not to depend on any sunscreen for primary protection from the sun's harmful ultraviolet rays. Hats, clothing and shade are still the most reliable sun protection available.
Products with high SPF ratings sell a false sense of security because most people using them stay out in the sun longer, still get burned (which increases risk of skin cancer) and subject their skin to large amounts of UVA radiation, the type of sunlight that does not burn but is believed responsible for considerable skin damage and cancer. High SPF products, which protect against sunburn, often provide very little protection against UVA radiation. Also, most people don't get the high SPF they pay for: people apply about a quarter of the recommended amount. In everyday practice, a product labeled SPF 100 really performs like SPF 3.2, an SPF 30 rating equates to a 2.3 and an SPF 15 translates to 2.
"Many sunscreens available in the U.S. may be the equivalent of modern-day snake oil, plying customers with claims of broad-spectrum protection but not providing it, while exposing people to potentially hazardous chemicals that can penetrate the skin into the body," said Jane Houlihan, EWG Senior Vice President for Research. "When only 8 percent of sunscreens rate high for safety and efficacy, it's clear that consumers concerned about protecting themselves and their families are left with few good options."
This year, new concerns are being raised about a vitamin A compound called retinyl palmitate, found in 41 percent of sunscreens. The FDA is investigating whether this chemical, when applied to skin that is then exposed to sunlight, may accelerate skin damage and elevate skin cancer risk. FDA data suggest that vitamin A may be photocarcinogenic, meaning that in the presence of the sun's ultraviolet rays, the compound and skin undergo complex biochemical changes resulting in cancer. The evidence against vitamin A is not conclusive, but as long as it is suspect, EWG recommends that consumers choose vitamin A-free sunscreens.
