If you’re like many people, you slather on sunscreen during hot summer days, then in winter, not so much. Short, cold days make it easy to forget that the sun doesn’t go into hibernation. While the intensity of ultraviolet B (UVB) rays diminishes in the winter, ultraviolet A (UVA) rays remain constant all year. And UVA rays are about 30 to 50 times more prevalent than UVB rays. Too much of either isn’t good for your skin, but UVA rays pose particular dangers to your skin. So, do not slack off on the sunscreen during the cold weather months!
