Sunscreen in Winter and Snow: A Guide for Minnesotans

When temperatures drop and snow blankets the ground, sunscreen may be the last thing on your mind. After all, isn’t sunscreen just for sunny summer days? Not quite. Minnesota winter sun protection doesn’t need to become a second full-time job.
The short answer
Do you need sunscreen during a Minnesota winter?
Use sunscreen on exposed skin when you’ll be outdoors, especially around bright snow, at higher elevations, or for longer stretches. Winter UV is often lower than summer UV, so the day’s UV Index and your actual exposure still matter.
Why UV rays don’t take a winter break
Cold air changes how the sun feels, not whether ultraviolet radiation is present. Clouds can reduce UV, but they don’t block it completely. Light cloud cover can still allow much of the sun’s UV radiation through, which is why a gray day isn’t automatically a no-protection day.
Snow changes the equation too. Fresh snow can reflect up to 80% of the UV radiation that reaches it. That doesn’t mean every snowy day literally doubles everyone’s exposure, but reflected UV can add to what reaches your face and eyes, particularly during skiing, snowboarding, or other long stretches outside.
Repeated UV exposure contributes to skin cancer and premature skin aging. The damage doesn’t hibernate just because your parka is doing most of the work.
There is some welcome perspective here: Minnesota’s UV Index is low on many winter days. Checking the forecast is more useful than assuming winter sun is harmless. You also don’t need to treat every walk to the mailbox like a day on the slopes.
How to choose a winter sunscreen
- Look for broad-spectrum protection. This means the product protects against both UVA and UVB radiation.
- Choose SPF 30 or higher. That’s the usual dermatologist recommendation for exposed skin. A higher number does not mean you can stay outside indefinitely or skip reapplication.
- Use a water-resistant option for outdoor activity. This matters when you’re sweating under winter gear or wiping your face.
- Pick a formula you’ll actually wear. Creamier or moisturizing sunscreens may feel better in cold, dry air. A moisturizer with sunscreen is fine if it is broad-spectrum SPF 30 or higher and you apply enough.
If a product stings, pills under other products, or leaves your skin miserable by noon, it probably won’t become a reliable habit. The best winter sunscreen is one that meets the protection basics and works with your skin.
A simple winter sun-protection routine
- Check the UV Index and your plans. A quick covered errand on a low-UV day is different from hours outside around bright snow.
- Apply sunscreen before you head out. Use it on exposed skin about 15 minutes before outdoor exposure. Remember the ears, nose, neck, hands, exposed scalp, and an SPF lip balm.
- Reapply during extended outdoor time. Follow the label. That typically means at least every two hours outdoors and after sweating, swimming, or toweling off.
- Let winter gear do some of the work. Hats, gloves, face coverings, UV-protective sunglasses, and ski goggles reduce how much skin and eye area is exposed.
- Account for dry skin. Apply moisturizer first if you need it, then sunscreen as the final skincare step before makeup. A moisturizing sunscreen can simplify the routine.
Minnesota activities that deserve extra attention
- Skiing and snowboarding: Snow reflection and higher elevation can increase UV exposure. Protect exposed skin and wear UV-protective goggles or sunglasses.
- Ice fishing: Hours on an open lake can mean prolonged exposure from above and reflection from snow or ice.
- Snowshoeing and winter hiking: A cold, clear day can still deliver meaningful UV during a long outing.
- Shoveling, walking, and outdoor work: Short sessions add up, particularly around midday or when the UV Index is moderate or higher.
Sunscreen is one part of the plan, not permission to stretch outdoor exposure. Clothing, shade when available, hats, and eye protection still matter. If you’re interested in how newer sunscreen filters fit into that picture, read what bemotrizinol means for sunscreen.
Protecting your skin all winter long
Winter sun protection is less about perfection and more about matching the habit to the day. Check the UV Index, cover what you can, and use broad-spectrum SPF 30 or higher on exposed skin when you’ll be outdoors. Your mittens already have most of the square footage handled.
