Winter sunscreen? Same formula, just don't forget it.

You don’t need to switch from chemical to mineral (or vice versa) just because it’s winter — but you absolutely need to keep wearing sunscreen, especially around snow.

Snow reflects up to 80% of UV rays. That’s like getting hit from above and below. And cold air doesn’t block UV — you can still burn on a cloudy, freezing day. If you’re skiing, snowboarding, or just walking around a snowy city, your face is getting plenty of exposure.

As for formulation: mineral sunscreens (zinc, titanium) sit on top of the skin and can feel drying or chalky in cold, dry air. Chemical sunscreens absorb into the skin and usually pair better with moisturizers. If your current sunscreen isn’t irritating you, stick with it. If winter wind makes your face raw, a hydrating chemical sunscreen (or a mineral one with moisturizing ingredients) will be more comfortable.

Bottom line: worry about wearing it, not which kind.
