UV rays are present year-round, even on cloudy days and during winter activities like skiing or snowboarding. Sun exposure doesn’t take a break just because it's cooler outside. In fact, the reflection of the sun off snow can intensify UV radiation. Protecting your skin daily, whether you're hiking through forests, enjoying a bike ride, or simply walking your dog, is crucial. Sun exposure accelerates aging, causes hyperpigmentation, and heightens the risk of skin cancer. So, it’s important to use sunscreen not just in the summer, but 365 days a year.
