UV rays penetrate winter clouds
No matter how thick those overcast clouds look in the winter, up to 80 percent of the sun’s rays can still penetrate them. Samer Jaber, MD, of Washington Square Dermatology in New York City explains that there are two types of UV rays that affect us, one of which is absolutely still very dangerous during winter. “UVA are always present, and can penetrate clouds, glass, and deeper into the skin. UVA damages deeper skin layers, resulting in premature aging and increased risk of skin cancer,” Dr. Jaber says. “UVB rays, on the other hand, vary in intensity and season. UVB rays are greater on sunny days during the summer. They damage the more superficial layers of the skin, resulting in sunburns and skin cancer,” he says. The takeaway: UVA rays are potent year-round, therefore your skin needs year-round protection.
Sunscreen has useful anti-aging properties
If there’s one season you want to work harder to prevent dry skin and wrinkles, it’s winter, so slather on that sunscreen and use it to keep your skin radiant. Winter’s harsh weather is incredibly drying and taxing on skin. Fortunately, sunscreen has proven anti-aging properties. (These new game-changing anti-agers can help too). “UV rays damage collagen and elastin in your skin, resulting in acceleration of fine lines and wrinkles,” says Dr. Jaber. “There have been numerous studies that have shown that regular use of sunscreen has anti-aging effects, but the best was an Australian study published in 2013,” says Dr. Jaber. “Researchers compared skin aging in 900 men and women from Australia over a four-year period. They found that those that used sunscreen daily, had no detectable increase in skin aging! Overall, they had 24 percent less aging than those that did not wear sunscreen. The average age of participants was 39, so it shows it is never too late to start wearing sunscreen!” Reach for a sheer sunscreen like SkinCeuticals Physical Fusion UV Defense SPF 50 that provides broad spectrum protection and has other anti-aging properties.
