It’s a common misconception that sunscreen is only essential during sunny summer months. As a dermatologist, I see many patients who neglect SPF during winter—unintentionally exposing their skin to damage. The truth is, UV radiation is present year-round, and protecting your skin during the colder months is just as crucial as it is in July.
Let’s break down the science behind winter UV exposure, the long-term benefits of wearing sunscreen year-round, and how to choose and use SPF properly during the colder seasons.
Does Your Skin Really Need Sunscreen in Winter? Absolutely. Here's Why:
1. UV Rays Don’t Take a Break
There are two types of ultraviolet rays that affect your skin:
- UVA rays (aging rays): penetrate deep into the skin and are present in equal intensity all year, regardless of temperature or cloud cover.
- UVB rays (burning rays): decrease slightly in intensity during winter but are still active enough to cause skin damage.
Even on a cloudy or snowy day, up to 80% of UV rays can penetrate your skin.
2. Snow Reflects UV Radiation
If you live in an area with snowfall, you’re actually at a higher risk of sun damage. Snow reflects up to 80% of UV light, essentially doubling your exposure—especially around the eyes and cheeks.
This makes SPF essential for:
- Winter hikes
- Ski trips
- Everyday commutes in snowy regions

3. Cold Air Weakens Your Skin Barrier
Winter weather dries out your skin, making the skin barrier more vulnerable. This means:
- More UV rays can penetrate
- Your skin is more reactive to irritation
- You’re more prone to long-term photoaging
Wearing sunscreen acts as an additional layer of protection to keep your skin barrier strong and resilient.
Key Benefits of Wearing Sunscreen in Winter
- Prevents premature aging: UVA rays cause collagen breakdown leading to wrinkles, sagging, and age spots—even in winter.
- Protects against pigmentation: Melasma and dark spots can worsen without daily SPF.
- Lowers skin cancer risk: Long-term UV exposure—even without sunburn—can lead to skin cancers like basal cell carcinoma and melanoma.
- Supports overall skin health: Sunscreen prevents inflammation, redness, and dryness caused by environmental stressors.
How to Choose the Right Sunscreen for Winter
Look for formulas that offer broad-spectrum protection, meaning they block both UVA and UVB rays. But in winter, it’s just as important to consider how a sunscreen supports your skin’s hydration and barrier function.
Ideal Ingredients for Winter Sunscreen:
- Zinc Oxide or Titanium Dioxide: gentle, non-irritating mineral filters
- Hyaluronic Acid: boosts hydration
- Ceramides and Niacinamide: support barrier repair
- Squalane or Shea Butter: add moisture without greasiness
Recommended SPF Level:
- At least SPF 30, even in winter
- Higher SPF if you spend extended time outdoors (skiing, snowboarding, hiking)
Texture Matters:
- Cream-based or lotion sunscreens are best in cold weather for their hydrating properties
- Avoid alcohol-heavy or gel sunscreens—they can be drying

Dermatologist Tips for Winter SPF Application
- Apply sunscreen as the last step in your morning skincare routine, before makeup.
- Use a nickel-sized amount for your face and more for neck and ears.
- Don’t skip areas like the lips, eyelids, ears, and under the chin—they’re often missed.
- Reapply every 2–3 hours if you’re outdoors, even in cold temperatures.
Final Thoughts from a Dermatologist
Just because the sun isn’t beating down on you doesn’t mean your skin is safe from damage. UV rays don’t hibernate in the winter, and neither should your sunscreen habit.
Incorporating SPF into your daily routine during the colder months protects your skin from aging, pigmentation, and dryness. It also ensures your skin remains healthy, resilient, and radiant all year long.
So yes—you absolutely need sunscreen in winter. Your future skin will thank you.
