Winter might feel like a break from the sun, but your skin is still at risk every day. The cold months bring their own set of UV challenges—from snow glare to weakened skin barriers to high-altitude exposure. By wearing sunscreen every day, you’re not just preserving your skin’s appearance—you’re investing in its long-term health. So the next time you zip up your winter coat, don’t forget the final (and most important) layer: sunscreen.
