Do You Need Sunscreen During Winter? Here's All You Need To Know
As the chill of winter finally begins to set in the capital, many of us are ready to pull out our favourite woolly jumpers, cosy scarves, and snug beanies. While it's easy to remember to layer up and protect ourselves from the cold, there's one skincare essential that often gets overlooked during the winter months: sunscreen. It might seem counterintuitive to slather on SPF when the sun feels like a distant memory, but studies and popular opinion alike seem to agree that sunscreen is a year-round necessity.

The Winter Sun
During the winter, with the sun's warmth no longer beating down on our skin, many believe that the risks of sun exposure disappear. However, this couldn't be further from the truth. Despite the temperature drop, ultraviolet (UV) radiation from the sun is still very much present, and it can damage our skin just as effectively in winter as it does in summer.
Up to 80% of UV rays can penetrate through clouds*, meaning even on overcast days, your skin is exposed to potential harm. Ultraviolet A (UVA) rays, in particular, are the main culprits behind skin ageing and penetrate deeply into the skin layers, contributing to wrinkles, sunspots, and the breakdown of collagen. On the other hand, Ultraviolet B (UVB) rays, which cause sunburn, maybe less intense in winter but are still present, especially at high altitudes or on reflective surfaces like snow.

Snow, Ice, And Sun
If you thought the risks ended with the absence of sunshine, think again. Winter sports enthusiasts, skiers, and snowboarders need to be especially vigilant. Snow can reflect up to 80% of UV rays**, doubling your exposure as the sunlight bounces back onto your face. Even on a clear winter's day, UV levels can be higher than expected due to this reflective factor.
This reflective exposure can lead to a phenomenon known as “snowburn,” which is essentially sunburn caused by the amplified UV radiation from the snow's reflective surface. Winter travellers, particularly those heading to mountainous regions, should take extra care as UV radiation increases by 10-12% for every 1,000 metres of altitude gain**. So, if you're skiing in the Spiti Valley or trekking in the Himalayas, sunscreen should be the first thing in your pack.
Why You Should Use SPF Indoors Too

“But I'm indoors most of the day,” you might argue. Unfortunately, that doesn't give you a free pass to skip sunscreen. UVA rays can penetrate glass windows, meaning your skin is still at risk while you're sitting near a sunny window, driving, or working in a well-lit office. This exposure might seem minimal, but over time, it contributes to cumulative skin damage, which manifests as pigmentation, premature ageing, and in severe cases, skin cancer.
Blue light from screens also adds another layer of concern. While the impact of blue light (also known as HEV light) on the skin is still being studied, some research suggests it can accelerate photo ageing, making sunscreen with broad-spectrum protection a wise choice for anyone spending long hours in front of a computer.

How To Choose The Right Sunscreen For Winter
When selecting a sunscreen for winter, you might want to opt for a hydrating formula. The cold air and indoor heating systems can strip the skin of moisture, so choosing a sunscreen that doubles as a moisturiser can help maintain a healthy skin barrier. Look for ingredients like hyaluronic acid, glycerin, or ceramides in your SPF to keep your skin plump and hydrated.
You also don't need to use the same heavy-duty, water-resistant sunscreens you might favour in summer. A lighter formula or even a moisturiser with SPF (with at least SPF 30) can be a good option for everyday wear, especially if you're spending more time indoors. However, if you plan to be outside for extended periods or engage in outdoor activities like hiking or skiing, a broad-spectrum sunscreen with SPF 50 is a better choice.

Applying sunscreen once in the morning isn't enough, even in winter. Sunscreen typically offers protection for about two hours, after which its effectiveness starts to wane. This is especially true if you're engaging in activities that involve sweating or wiping your face. The rule of thumb is to reapply every two to three hours if you're outdoors and once in the middle of the day if you're primarily indoors.
For those worried about disrupting their makeup, setting sprays with SPF can be handy. These products provide a quick and easy way to top up your protection without needing to redo your entire face.
Incorporating sunscreen into your winter skincare routine may feel like an extra step, but it's a small price to pay for healthy, youthful-looking skin. Whether you're outdoors enjoying a brisk walk, hitting the slopes, or simply sitting by a sunny window, sunscreen serves as your best defence against the subtle yet significant damage caused by UV rays.
So, as you pile on your winter layers, don't forget to add one more: a layer of SPF. Your future self will thank you for it, with glowing, healthy skin that endures the test of time.
