The surprising truth about cold-weather sun damage
When the temperature drops and the sun feels softer, it’s easy to think your sunscreen can take a vacation. But here’s the truth: your skin needs SPF protection every single day — even in winter.
I know it sounds counterintuitive. The air is crisp, the days are shorter, and you might barely see the sun between clouds. But the rays that age your skin — the ones that cause wrinkles, dark spots, and collagen breakdown — don’t take a season off.
The Winter Sun Still Ages Skin
There are two types of ultraviolet rays that affect your skin:
- UVB rays cause sunburn. These do get weaker in winter.
- UVA rays cause aging. These are just as strong year-round — and they penetrate clouds and glass.
That means even when it’s cloudy, rainy, or snowing, UVA rays are still reaching your skin, silently breaking down collagen and accelerating signs of aging.
Think of UVA as the “Aging Rays.” They’re present all day, all year — whether you feel the heat or not.
Snow & Altitude Make UV Exposure Worse
If you love skiing, hiking, or even a snowy walk, here’s something surprising: snow reflects up to 80% of UV rays. That means you’re getting hit twice — once from the sky and again from the ground.
And if you’re in higher altitudes (like the mountains), UV exposure increases with elevation. That’s why winter sunburns happen more often than people realize.
The Hidden Culprit: Indoor Light Exposure
Even if you’re indoors most of the day, UVA and blue light from screens can still stress your skin. Over time, this contributes to dullness, uneven tone, and fine lines, especially around the face and neck. This is why I remind all my clients: sunscreen is skincare. It’s your daily dose of protection, not just for the beach, but for every environment your skin lives in.-create a little fun fact section.
Pro tip: Epicutis Hyvia Crème is a moisturizer that provides 24hr hydration and provides blue light protection!
Choosing the Right Sunscreen SPF for Winter
In colder months, your skin may feel drier or more sensitive, so pick a sunscreen that also nourishes and calms.
Pro Tip: Swap your lightweight summer gel SPF for a richer, barrier-protective formula that keeps skin hydrated and calm.
My winter sunscreen picks:
Epicutis Lipid Shield is a dreamy, cushiony mineral sunscreen that calms inflammation, supports collagen, and leaves skin feeling soothed, protected, and irresistibly soft.
“This sunscreen feels so yummy and cushy on the skin—you’ll actually look forward to putting it on every day.” - Mary S.
Colorescience Face Shield Glow is a pearlescent mineral sunscreen protects from UVA/UVB rays, pollution, blue light, and infrared damage while adding a luminous champagne glow.
"I mix this and the flex together to give my skin the perfect glow. I use this everyday and haven't had many breakouts from it." -Amanda R.
Tizo Ultra Zinc is a soothing mineral sunscreen formulated for sensitive, easily irritated skin. Its moisturizing, protective formula helps strengthen the skin barrier while shielding against daily UV exposure.
“When I’m out braving the cold weather, this is my go-to for protecting my skin barrier from dryness and UV.” -Jeana
FAQ
Do I really need sunscreen in winter?
Yes — absolutely! Even though UVB rays (which cause burns) are weaker in winter, UVA rays (which damage collagen and increase early signs of aging) are just as strong year-round. These rays penetrate clouds and glass, meaning your skin still needs protection even when it’s cold or cloudy.
Can I skip sunscreen if I’m mostly indoors during the winter?
Not quite. UVA rays can penetrate through windows, and blue light from screens can also stress the skin over time. If you spend a lot of time near windows or on digital devices, a lightweight, mineral SPF still makes a big difference.
Does snow increase sun exposure?
Yes — snow reflects up to 80% of UV rays, which means you’re getting hit from above and below. If you enjoy winter walks or snow sports, SPF is a must. Don’t forget to reapply every two hours and protect your lips with an SPF balm.
What kind of sunscreen should I use in winter?
Winter skin tends to be drier, so opt for hydrating sunscreens that double as moisturizers. Look for ingredients like zinc oxide, titanium dioxide, niacinamide, and antioxidants to calm and protect your skin barrier. Jeana’s favorites include:
- Epicutis Lipid Shield SPF 30 (for dry sensitive skin)
- Colorescience Sunforgettable Total Protection Face Shield Glow SPF 50 (for dull, dry skin)
- Tizo Ultra Zinc SPF 40 (for dry sensitive skin especially for outdoor activities)
Should I wear SPF on cloudy or rainy days?
Yes — UVA rays can penetrate clouds, fog, and even rain. About 80% of UV rays still reach your skin when it’s overcast. That’s why consistent SPF use, no matter the weather, is one of the best habits for long-term skin health.
How can I remember to apply sunscreen in winter?
Keep it simple:
- Apply it every morning after your moisturizer, just like brushing your teeth.
- Store your sunscreen next to your skincare essentials so it becomes routine.
- Choose a formula you love — something hydrating and lightweight enough that you look forward to putting it on.
The Bottom Line
The sun might feel gentler in winter, but the damage it causes is just as real. Wearing sunscreen SPF every day — even on cloudy or snowy mornings — is one of the simplest, most effective ways to preserve your skin’s health and glow for years to come.
