Winter sun is still sun
UVA rays pass through clouds and reflect off snow and glass, reaching your skin even on overcast January days. They drive premature aging and skin cancer risk year-round, not just in summer.
A simple daily habit
Apply a broad-spectrum SPF 30 or higher every morning to your face, neck, and the backs of your hands. Reapply if outdoors for long stretches, and pair it with a moisturizer to counter winter dryness.
