Do You Need Sunscreen in Winter? Why Your SPF Routine Shouldn't Stop in October

Every year, right around the end of October, something predictable happens: the sunscreen bottle migrates from the bathroom counter to the back of a drawer, where it sits until Memorial Day. It feels logical. The days are shorter, the air is colder, and nobody comes home from a November afternoon looking pink.

But the logic doesn't hold up. A 2024 survey from the American Academy of Dermatology found that nearly one in five Americans didn't know it was possible to get sunburned in winter. Cold weather and UV exposure are two completely separate things — and the gap between how protected people feel and how protected they actually are is widest in the months nobody is thinking about sunscreen.

UVA Rays Don't Take the Winter Off

Sunlight reaching your skin comes in two forms that matter here. UVB is the burning ray — the one that gives you that hot, tight, red feeling after a long beach day. UVB does weaken significantly in winter, because the sun sits lower in the sky and its rays travel through more atmosphere to reach you.

UVA is a different story. UVA penetrates deeper into the skin, stays remarkably consistent across seasons, and passes straight through clouds and window glass. It's the ray most associated with photoaging — fine lines, loss of firmness, and the uneven pigmentation that shows up as dark patches years after the exposure that caused it.

So the winter trade-off is this: you're far less likely to burn, and roughly as likely to accumulate the slow, cumulative damage that nobody notices until it's visible. That's precisely why dermatologists treat sunscreen as a year-round product rather than a seasonal one.

Snow, Clouds, and the Two Biggest Winter Myths

Two beliefs do most of the damage in cold months.

The first is that clouds are protective. Up to 80% of UV radiation passes through cloud cover. An overcast January sky filters the light you can see far more than the light you can't.

The second is that snow is just scenery. Fresh snow reflects as much as 80% of the UV that hits it, bouncing it back up at your face, under your chin, and into the shadowed areas sunscreen users usually skip. Sand, by comparison, reflects around 15%. A bright, clear day after a snowfall can deliver more UV to your face than an afternoon at the beach — which is also why anyone heading to the mountains should read our guide to sun protection on the slopes.

Winter Skin Has a Second Problem: It's Dry

There's a practical reason people abandon sunscreen in winter beyond forgetfulness. Indoor heating, low humidity, and hot showers strip moisture from the skin barrier. A sunscreen that felt light in July can feel heavy, chalky, or flaky on dry December skin — and a product that feels bad is a product you stop using.

This is where texture does more work than the SPF number. A gel formula sits differently than a thick cream: it absorbs without leaving a film, layers cleanly under moisturizer and makeup, and doesn't pill when you've got three products on your face. Our SPF 50 Face Gelée was built around that texture problem specifically — broad-spectrum protection in a weightless gel that disappears instead of sitting on top of dry skin.

How to Keep Wearing SPF When It's 40 Degrees Out

The winter routine doesn't need to be elaborate. It needs to be automatic.

• Attach it to something you already do. Sunscreen goes on after moisturizer, before makeup, every morning — not as a decision, but as a step.
• Focus on what's exposed. In winter that's usually face, ears, neck, and the backs of your hands. Hands get enormous cumulative exposure and almost no protection, which is why they often show age before the face does.
• Don't skip the commute. Side-window glass blocks most UVB but very little UVA, so a daily drive is a daily dose.
• Reapply on long outdoor days. Hiking, skiing, a full day of errands — the two-hour rule doesn't change because the temperature did.
• Keep a backup where you'll see it. Desk drawer, car, coat pocket. Visibility beats willpower.

What About Vitamin D?

It's the most common objection, and it's a fair one — vitamin D levels do dip in winter for people at higher latitudes. But the research consistently shows that real-world sunscreen use doesn't meaningfully reduce vitamin D synthesis, largely because almost nobody applies the full laboratory amount to every exposed inch of skin. If your levels are a concern, diet and supplementation are a far more reliable fix than deliberately under-protecting your face for a few months.

Body Protection Still Matters Too

If your winter involves a warm-weather escape, a ski trip, or simply an outdoor job, exposed skin below the neck needs the same attention. A broad-spectrum body formula like our SPF 30 Body Gelée covers shoulders, arms, and chest without the greasy drag of a traditional lotion. And if you want both steps handled in one go, the Summer Duo pairs face and body together.

The Short Version

Winter changes how much you burn. It doesn't change how much you age. UVA is steady year-round, clouds barely filter it, and snow actively amplifies it. Wearing SPF from November through March isn't about being cautious — it's about not undoing eight months of a habit you've already built.

The bottle shouldn't go in the drawer. It should just move to the front of the shelf.
