Just because it's cold outside doesn't mean you can put away your sunscreen. Even though there are plenty of Winter layers to keep you warm (and covered), don't forget to keep your face, neck, and hands protected from the sun's harmful rays.
Snow and ice reflect UV rays. Sure, it might seem gray outside, but snow and ice reflect the sun's rays. This means you should keep your SPF routine up on a daily basis. Heading to the slopes? You'll definitely want a stronger sunscreen formula made for Winter sports — because windburn is most uncomfortable.
There's a thinner ozone layer. The colder seasons mean the ozone layer is thinning out. So, there is less ozone in our atmosphere to absorb the sun's UV radiation. Even though it feels colder outside, there's actually more of the sun's harmful rays hitting the earth's surface and, yes, your skin. Prevent getting a cold-weather burn by using a product with SPF 30 or more.
