Ski and sun: essential tips for safe sun exposure while skiing

Why sun protection matters just as much on the slopes as it does at the beach

When we think of sunburns, our minds often go to summer holidays, sandy beaches, and hours spent lounging near the water. But what many people don’t realize is that the risk of UV exposure is just as serious in winter, especially while skiing or snowboarding. In fact, the combination of altitude and snow reflection makes the mountains a prime setting for sun damage, sometimes even more intense than at sea level.

At Juillet Juillet, we are dedicated to sun safety year-round. While we’re best known for our UPF 50+ anti-UV swimwear, our mission goes beyond summer. Skin protection isn’t seasonal, it’s essential, and that’s especially true on the snowy slopes.

In this article, we’ll break down why sun safety in winter is crucial, how UV rays behave at high altitudes, and which habits and products will help keep your skin healthy while you enjoy the cold and the thrill of skiing.

Why winter sun can be deceptively dangerous

It’s easy to associate cold temperatures with low sun risk. But this is one of the biggest myths in skin protection. Cold air does not block UV rays, and snow doesn't act as a shield, in fact, it acts as a mirror. Snow reflects up to 80 percent of UV radiation, which means your skin is hit twice: once from above, and once from below.

And then there’s altitude. With every 1000 meters of elevation, UV exposure increases by approximately 10 percent. So if you’re skiing at 2000 meters, you could be exposed to 20 percent more UV rays than at sea level even on a cloudy day.

What’s more, the atmosphere is thinner at altitude, offering less natural filtration of harmful rays. This means even on overcast ski days, UVA and UVB rays can still reach your skin and cause damage.

The most vulnerable areas: what skiers often overlook

When you're bundled in ski gear, it’s easy to assume your body is well protected and for the most part, it is. But certain areas remain exposed and particularly at risk. These include the face, nose, ears, lips, scalp, and the neckline if your jacket or helmet isn’t fully closed.

These so-called "sun terraces" are frequently overlooked when applying sunscreen and are also the most exposed to reflection from the snow. In extreme conditions, they can burn quickly, even after short periods outdoors.

That’s why your ski beauty ritual should always begin with sun protection, just as it does on a summer beach day.

Building a winter sun protection routine that works

First and foremost, choose a broad-spectrum sunscreen with an SPF of 30 or higher though SPF 50+ is strongly recommended for skiing, especially at high altitudes or in spring, when snow reflects more sunlight. Opt for a water-resistant formula that can withstand snow, sweat, and wind.

Apply your sunscreen at least 20 minutes before exposure, giving the active ingredients time to absorb fully. This ensures that the protection is active by the time you step onto the slopes. Cover the entire face, paying particular attention to the nose, ears, lips, and under the chin areas often missed.

Don’t forget reapplication. Even the best sunscreen wears off with friction from scarves, gloves, or helmet straps. Reapply every 90 minutes to two hours, especially if you wipe your face or feel sweaty. Keep a compact mineral sunblock stick in your pocket it’s a practical way to touch up protection on the go.

Mineral sunscreens, often made with zinc oxide or titanium dioxide, are an excellent choice for winter sports. They create a physical barrier on the skin that reflects UV rays immediately upon application no absorption time needed. Plus, they tend to be well tolerated by sensitive skin and remain stable in cold conditions.

If your skin is reactive or prone to dryness, select hypoallergenic formulas without fragrance, alcohol, or parabens. The cold and wind already challenge your skin barrier, so your sun protection should soothe, not irritate.

Don't neglect the lips and the eyes

Lips are particularly vulnerable to UV damage because the skin is thinner and lacks melanin. Always apply a lip balm with SPF 30 or more, and reapply frequently, especially after drinking or eating.

As for the eyes, they are not immune to sun damage. The high reflectivity of snow can cause a condition known as photokeratitis, a painful burn on the surface of the eye also known as “snow blindness.” To prevent it, invest in UV-protective ski goggles that filter 100 percent of UVA, UVB, and even UVC rays. Unlike regular sunglasses, goggles offer full coverage around the eyes and are designed to stay put in motion.

Protective gear as a layer of sun safety

While our core focus at Juillet Juillet is anti-UV swimwear, the principle of wearing protection rather than just applying it applies equally in the mountains. Just as our UPF 50+ swimsuits protect your skin from the sun at the beach, well-designed winter gear acts as a physical shield against radiation, cold, and wind.

Look for ski jackets and helmets that close tightly at the neck and forehead. Choose gloves with extended cuffs, and avoid mesh fabrics that let UV rays through. If you're planning a sunny spring ski trip, consider adding a lightweight UPF-rated neck guard  to your kit, it can make all the difference for prolonged exposure.

What to do if you get sunburned while skiing

If you do get sunburned, act quickly. Get out of the sun and into the shade or indoors as soon as possible. Cool the affected area with a clean compress or gentle mist (not ice), and apply a soothing, fragrance-free lotion or aloe vera gel.

Stay well hydrated. Sunburn dehydrates the skin and the body, especially at high altitude where the air is dry. Avoid exfoliants or active ingredients like retinol for several days, and give your skin time to heal.

If blisters form or the burn becomes painful to touch, seek medical attention to prevent infection or complications.

Embracing sun safety year-round

At Juillet Juillet, we believe that sun protection is not a summer concern, it’s a lifelong habit. Whether you're by the sea or on the slopes, your skin deserves the same attention and care.

By integrating sun protection into your winter sports routine, you're not only preserving your skin’s health, but also preventing cumulative damage that can lead to premature aging, pigmentation, and skin cancer. The right products and habits can help you enjoy your time on the slopes fully and safely.
