the Best Sunscreen for You
Let’s face it, you buy sunscreen because you don’t want to burn and look like a tomato, get skin cancer, wholesale nba jerseys china or wind up with wrinkled skin when you’re way too young for those age defining wrinkles. But when you walk into a pharmacy to buy your Defense Against the Sun in a bottle, the options are, well, overwhelming. News in partnership with Pharmacy Times surveyed 294 pharmacists to find out which sunscreen brands they recommend most often. Neutrogena came out as the winner with 52 percent of the vote, followed by Coppertone at 30 percent and Hawaiian Tropic at 10 percent. Those oil free qualities, he adds, make it less likely a sunscreen will cause undesirable side effects such as acne or rashes.
But just because Neutrogena rates No. Food and Drug Administration.
While sunscreen ingredients may be similar, the bottle labels are as diverse as the vitamins the next aisle over. News asked David Leffell, a professor of dermatology and surgery at the Yale School of Medicine and scientific adviser for Coppertone, and David Fisher, chief of the Massachusetts General Hospital Department of Dermatology, what you need to know when shopping for a sunscreen. They also shared their best sun wholesale nhl jerseys china shielding secrets.
What’s the best SPF value?
SPF, which stands for sun protection factor, only measures your protection from ultraviolet B exposure (more on that below) and has values as low as 2 to more than 100. But if you’re not really sure what the number means, you’re not alone. “People are so confused about this,” Leffell says. “Consumers often think the higher the SPF, the less frequently they have to put it on, but the SPF number is not like the proof in an alcoholic drink. In other words, the higher the SPF, you don’t get a stronger sunscreen.”
Most dermatologists recommend SPF 30 for the average person, since it blocks about 97 percent of UVB rays. So is SPF 100 a superhero sunscreen that will defend you against that other 3 percent? Not exactly. As Leffell explains, “the higher you go on the SPF, the tinier the improvement in the wholesale nfl jerseys UVB blockage.” For example, SPF 50 blocks about 98 percent of UVB rays. Anything higher provides no significant difference in protection, according to the FDA, which recently proposed to limit the maximum value as SPF 50+.
Fisher stresses that the SPF doesn’t matter as much as how you apply it and how often you reapply it. For instance, say you slather on SPF 30. “If you forget to put it back on again after you’ve been in the pool and much of it has washed off, you may have gone from a 30 to a 2,” Fisher says.

Does skin color change what SPF you need?
For the most
part, the SPF 30 recommendation holds true for all skin types. “The most
common thing I see is people with darker skin who get skin cancer and
say, ‘Geez, I didn’t think I needed to use sunscreen. I thought I was
naturally protected,'” Leffell says. Though people with darker skin do
have some natural protection (black skin has an SPF 13), a darker tone doesn’t give you immunity against cancer inducing rays.
What’s the difference between UVA and UVB?
When selecting a sunscreen, you want the label to say “broad spectrum protection,” which means it blocks UVA and UVB rays. These rays are why 1 in 5 Americans get skin cheap nba jerseys cancer, including melanoma and basal cell carcinoma the most common type of cancer, according to the Skin Cancer Foundation.
UVB. Think of B for burning, as these rays trigger what Fisher calls an “alarm signal of redness, pain and swelling” meant to get you out of the sun. Leffell, who discovered the skin cancer gene in 1996, says UVB rays are most associated with causing mutations that lead to skin cancer.
Symptoms: They should be obvious. “You know if you were successful or if you failed [to protect yourself] on the basis of whether you had burning or not,” Fisher says.Articles Connexes：
