The experts from ISDIN are here to share their latest skin care advice.

Hereʼs a little-known fact: Sunlight in the winter can be just as harmful as summer rays. Whether you're hitting the slopes for a ski vacay or enjoying a brisk walk outdoors, sunscreen is still a good idea during the colder months. From the sun protection experts at Barcelona-based ISDIN, here are five reasons to make sun protection a winter skin care essential:

• Snow reflects UV rays

• Higher altitudes mean higher UV exposure

• Sunburns can happen in winter

• Skin memory matters

• Certain solutions are perfect for winter wear

1) Snow reflects UV rays

Did you know snow reflects up to 80% of the sunʼs UV rays? Thatʼs eight times more than water! This intense reflection amplifies the risk of UV exposure, meaning your skin is more vulnerable to damage, even on cloudy days.

Whether youʼre snowshoeing in a winter wonderland or spending hours on the ski hill, the sunlight bouncing off snow can increase your UV exposure. Applying sunscreen before heading outdoors ensures youʼre ready to face this unexpected winter challenge.

Remember, areas like your nose and cheeks bear the brunt of exposure, but donʼt forget about the underside of your chin or your lips, which can also catch reflected rays. Keep in mind that you should reapply your favorite sunscreen at least every two hours to help ensure protection.

2) Higher altitudes mean higher UV exposure

In the mountains, youʼre closer to the sun, which means the atmosphere offers less protection from harmful UV rays. For every 1,000 feet you ascend, UV radiation increases by roughly 3%. That means if youʼre skiing or hiking at a popular resort at 10,000 feet, you could be exposed to 30% more UV radiation than at sea level.

This heightened exposure makes SPF for skiing a critical step in your routine. Beyond just sunscreen, consider using physical blockers such as a helmet, neck gaiter and UV-protective clothing to further reduce exposure. Remember, UV rays penetrate clouds, so even overcast days in the mountains still require protection.

3) Sunburns can happen in winter

The combination of snow, sun and altitude creates a risk for winter sunburns. Have you ever wondered, “Can you get a sunburn in the winter?ˮ The answer is yes. Many assume the sun isnʼt as strong during the colder months, but the reflective properties of snow and heightened UV exposure at high altitudes may prove otherwise.

Whatʼs more, cold temperatures can numb your skin, making it harder to notice the telltale signs of burning. This means you could come back from your ski day with more than just chapped lips and rosy cheeks—you might also be nursing a sunburn. You can combat this by following the sun protection tips we mentioned: reapplying sunscreen every two hours and wearing protective gear like goggles and masks to shield your face.

4) Skin memory matters

Your skin remembers every moment of unprotected UV exposure, and the effects can accumulate over time. Without the right precautions, exposure to sunlight in the winter can lead to long-term consequences such as photoaging (wrinkles, fine lines and dark spots) or even serious conditions such as skin cancer.

By incorporating sunscreen into your winter routine, youʼre actively helping to prevent further damage and maintain healthy skin. Make it a habit to apply sunscreen daily—even if you're just running errands or commuting. Consider using products with added antioxidants to combat the oxidative stress caused by UV rays. This small daily effort can make a big difference in your skinʼs long-term health.

5) Certain solutions are perfectly suited for winter wear

When choosing sun care products for snowy conditions, look for broad-spectrum sunscreens that protect against both UVA and UVB rays and a mineral powder for touch-ups. Here are some dermatologist-favorite options to help keep your skin safe:

Extra winter skin care tips

Protect your eyes: Snow glare can be intense, so donʼt forget UV-blocking sunglasses or goggles. These not only protect your eyes but also the delicate skin around them.

Stay hydrated: Winter weather is notoriously drying. Use a targeted moisturizer or hydrating serum to keep your skin comfortable, especially after a long day outdoors.

Post-sun care matters: If youʼve spent a lot of time outside, treat your skin to a soothing after-sun product to help it recover.

Final tip: Pack your SPF in winter and enjoy the weather

Whether you're planning a ski trip or just a cold-weather hike, donʼt underestimate the power of SPF in winter. The combination of reflective snow, higher altitudes and prolonged outdoor exposure makes sunscreen your most important winter accessory. Embrace the beauty of winter without compromising your skinʼs health. Pack your SPF, protect yourself and make the most of the cold weather.
