Before you head outside to enjoy the extra sunlight, take a few minutes to learn the difference between UVA and UVB rays – and catch up on the FDA’s sunscreen-labeling regulations.
·A is for aging. UVA rays are always present when the sun is out, no matter how sunny (or overcast) the weather may be. They are used in tanning beds, and were once actually considered the “safe” rays. Now, though, we know that these powerful rays can penetrate clouds, glass (think car windows), and even some clothing – penetrating deep into the skin and damaging underlying cells. You can blame your sunspots, leathery skin, wrinkles, and other skin-aging ailments on UVA rays. Large doses can also contribute to cancer.
