Sun, Sunscreen and Your Skin - the Low Down

Every year the Environmental Working Group (EWG) releases their annual guide to sunscreens,1 and this year's data again shows that you must be very cautious when choosing sunscreen to apply to your skin.

LOOK OUT FOR THESEWoman In Pool

1. Oxybenzone This is one of the most troublesome ingredients found in the majority of sunscreens.Oxybenzone is believed to cause hormone disruptions and cell damage that may provoke cancer.

2. Retinyl Palmitate (Vitamin A palmitate) Sunscreen products may actually increase the speed at which malignant cells develop and spread skin cancer because they contain vitamin A and its derivatives, retinol, and retinyl palmitate.

3. Fragrance Beware of products that contain synthetic fragrance, as this term describes any number of harmful chemicals that do not have to be listed individually on the label.

WHAT TO CHOOSE

  • Avoid Spray Sunscreens
  • Protects Against Both UVA and UVB Rays: SPF only protects against UVB rays, which are the rays within the ultraviolet spectrum that allow your body to produce vitamin D in your skin.  But the most dangerous rays are the UVA rays. Make sure your sunscreen protects against both.
  • Avoid Sunscreen Towelettes or Powders: Dubious protection
  • Avoid Spray Sunscreens: Contain toxic particles that can be inhaled

Does Your Sunscreen Offer UVA Protection?

Even a sunscreen that claims to be "broad spectrum" may not provide adequate UVA protection. As EWG reported:5

"After a 34-year process of reviewing sunscreen safety and efficacy, the U.S. Food and Drug Administration has implemented enforceable rules on sunscreen marketing and UVA protection. The FDA allows American sunscreen makers to claim their products are 'broad spectrum,' even though many offer much poorer UVA protection than sunscreens sold in other countries.

Based on the products in our 2014 database, EWG estimates that about half of all beach and sport sunscreens could not be sold in Europe because they provide inadequate UVA protection."

So, look for a sunscreen that contains the minerals zinc oxide and titanium dioxide.

Use Sunscreen When Absolutely Necessary

If you work in the outdoors, are planning a trip outdoors, or if you need to protect sensitive areas of your face (like around your eyes), safe sunscreen is certainly recommended. But if you apply sunscreen every time you're out in the sun, you'll block your body's ability to produce vitamin D.

Optimizing your vitamin D levels may reduce your risk of as many as 16 different types of cancer, including pancreatic, lung, ovarian, breast, prostate, and skin cancers.

Studies show melanoma mortality actually decreases after UV exposure. Moderate exposure to sunlight, particularly UVB, is protective against melanoma (the deadliest form of skin cancer) due to the vitamin D your body produces.

5 Top Sunshine Tips

Spend some time outdoors in the sun regularly, but do so with some commonsense precautions:

  • Expose your skin to sunlight for short periods daily
  • If you're in the sun for longer periods, cover up with clothing, a hat or shade
  • Shield your face from the sun daily using a safe sunscreen or a hat.
  • Consider the use of an "internal sunscreen" like astaxanthin to offer additional protection.
  • Consume a healthy diet full of natural antioxidants. Fresh, raw, unprocessed foods deliver the nutrients that your body needs to maintain a healthy balance of omega-6 and omega-3 oils in your skin, which is your first line of defense against sunburn.

Think Twice Before you Lay on a Tanning Bed

Ten years ago, I tried a tanning bed ONCE, at the encouragement of a teenaged niece. I am sightly claustrophobic (thankfully) so didn't repeat the experience.  I also wasn't sure I felt safe in the first place. 6 years later, I had a small spot on my chest that turned out to be Squamous Cell Cancer.  Thankfully I caught it very quickly and had it removed.

UV light is not something to mess with.  In my opinion companies that offer tanning bed services are in fact socially and morally irresponsible in light of the prevalent data about the dangers.  To me, they are no better than Cigarette companies who promote and make their wealth from selling a product that has no Benefits, and a rather long list of Risks!

Well, chances are you know someone who has used a tanning bed, or you may have tried it yourself. Please read this article and pass it on to anyone who may be deterred from repeating the experience, or trying it for the first time.

We need to take care of each other.

Use Of Tanning Beds Common, Despite Cancer Risks

Ed Andrieski/APJodi Duke, a 35-year-old melanoma survivor living in Aurora, Colo., shows the scar left on her arm from melanoma. She used tanning beds as a teen and advocated for a bill to regulate tanning in the state that failed in 2007.

Who's really hooked on tanning beds?

Odds are she's young, white and lives in the Midwest.

Figures just published in the Morbidity and Mortality Weekly Report paint a detailed picture of indoor tanning habits across the country.

Overall, in 2010 about 5.6 percent of adults used a tanning bed, or other device that blasts UV rays at skin to darken it. Tanning sprays didn't count.

But the most likely adult users, as you might have guessed, are women between 18 and 25. Around 30 percent of white women in that age group had used an indoor tanning machine of some sort in 2010.

"I am astounded" by the results, Dr. Len Lichtenfeld, deputy chief medical officer of the American Cancer Society, told the Associated Press.

People who go in for indoor tanning tend to do it quite a bit.  About 58 percent of white women who tanned indoors did it 10 times or more in a year.  For white men who tanned indoors, the comparable figure was 40 percent.

Indoor tanning equipment that exposes a person to UV rays (not tanning spray) carries the risk of skin cancer. The frequent tanning sessions found in the survey increase the risk.

"What tanning beds are doing is concentrating the same kind of rays that we get from the sun; so, you're getting a much bigger dose" than you would from the same amount of time outdoors, Memorial Sloan-Kettering Cancer Center's Dr. Allan Halpern, told Shots when we talked to him about an earlier study on the risks of indoor tanning.

Melanoma, a type of skin cancer, is on the rise. And the increase in melanoma is greatest among young women, a point the researchers say could be related, in part, to tanning bed use.

"Indoor tanning is particularly dangerous for younger users because indoor tanning before age 35 years increases the risk for melanoma by 75%," wrote the researchers, who are from the National Cancer Institute and the Centers for Disease Control and Prevention.
