Just because it's cold outside doesn't mean you can put away your SPF. Even though there are plenty of Winter layers to keep you warm (and covered), don't forget to keep the exposed skin on your face, neck, and hands protected from the sun's harmful rays.
Snow and ice reflect UV rays. Sure, it might seem grey 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 sun protection formula made for Winter sports — windburn is most uncomfortable, and "goggle eyes" suit nobody!
There's a thinner ozone layer. The ozone layer is thinning out, meaning there is less ozone in our atmosphere to absorb the sun's UV radiation. Even though it feels colder outside, there are actually more of the sun's harmful rays hitting the Earth's surface, and your skin. Prevent getting a cold-weather burn by using a product with SPF 30 or more.
Even if you don't burn, you may age. Good SPF products don't just protect you from the UVB rays that can cause sunburn, they also protect from UVA rays, which are responsible for ageing the skin prematurely (and reducing its defences, which can increase the risk of skin cancer). We're exposed to these rays to some extent every day, even when the temperature is low and the sky is dull. Using a broad spectrum SPF product year-round protects the skin from more than just redness, it'll keep you looking younger, and keep your skin healthier, for much longer.
