Sunscreen in January? Here's why, honestly.

MOGLORD · WEB STORY Clouds, snow and office windows — what winter does to your skin.

“No sun, no sunscreen needed”

1 S THE MYTH Winter weakens UVB, the burning ray. But UVA — the aging, tanning ray — stays strong all year round.

2 S THE SCIENCE Up to 80% of UV rays get through cloud cover, and UVA crosses window glass. A desk by the window counts.

3 S THE SNOW FACTOR Sand reflects ~15%, water ~10% — snow nearly doubles exposure. Ski trips burn faces fast and hard.

4 S WHAT IT PREVENTS Most visible skin aging is photo-aging. Daily SPF is the cheapest anti-aging step that actually exists.

5 S THE DOSE Squeeze sunscreen along your index and middle fingers — that's the amount SPF ratings are based on.

6 S THE ROUTINE Moisturizer first, sunscreen last, 15 minutes before heading out. Reapply every 2 hours outdoors.

7 S WHICH ONE Look for “broad spectrum” and SPF 30–50. A moisturizer with SPF is fine for office days, used generously.
