You might think that using sunscreen in winter is unnecessary, especially when temperatures drop and the intense heat of the sun you're used to in summer is gone. But the truth is quite different; ultraviolet rays do not disappear with the cold weather, but rather easily penetrate clouds and reach your skin even on days that seem sunless.
That's why it's important not to skip sunscreen during this season, as neglecting it means exposing your skin to gradual damage, the appearance of hyperpigmentation, and loss of elasticity over time. In this article, you'll learn why sunscreen is still needed in winter, and the differences in the sun's effects between seasons.
Is Sunscreen Necessary in Winter?
Despite the cold weather and shorter daylight hours in winter, using sunscreen remains an essential step in your skincare routine. UV rays do not stop when temperatures drop; they continue to penetrate clouds and glass and reach the skin, meaning your skin remains exposed to their effects even on cloudy or cold days.
Consistently applying sunscreen during this season helps protect your skin from premature wrinkles, dark spots, and sunburn, and also contributes to reducing the risk of skin cancer and maintaining an even, healthy skin tone.

Why are UV rays persistent?
UV rays, both UVA and UVB, do not disappear with a drop in temperature or when the sun is hidden behind clouds. These rays can easily penetrate clouds and glass, and they also reflect off white surfaces like snow, sometimes increasing the intensity of exposure. Therefore, the presence of clouds or cold weather does not mean the rays disappear or that their danger to your skin is gone.
How do rays affect the skin in winter?
Even during winter, using sunscreen is essential because UV rays can cause noticeable damage to the skin; they lead to loss of skin elasticity and the appearance of premature wrinkles, in addition to worsening hyperpigmentation and dark spots. Continuous exposure to them, even from behind windows, weakens skin cells and increases the likelihood of skin cancer over time. Therefore, daily protection with appropriate sunscreen remains a necessity all year round.
What is the difference between sun in summer and winter?
In summer, the sun is more direct, increasing the intensity of UVB rays that cause burns and skin inflammation, so you need greater protection during direct exposure. In winter, this intensity decreases slightly, and sunlight appears weaker, but its effect does not completely disappear, as UV rays remain capable of causing cumulative damage to the skin over time.
Why are rays harmful in winter?
You might think that winter sun rays are safe due to the cold weather, but the truth is that UV rays are not affected by temperature. Even on cloudy or cold days, UVA rays intensely pass through clouds and glass, causing premature wrinkles, hyperpigmentation, and deep damage to the inner layers of the skin, especially if you don't use sunscreen regularly.
What is the role of snow and glass reflection?
A large portion of the sun's rays reflects off white surfaces like snow or off glass, increasing your skin's exposure to radiation from multiple directions. This reflection doubles the effect of the rays, especially during outdoor activities such as skiing or traveling to mountainous areas. For this reason, skin protection remains essential in winter just as it is in summer, as even with a lower UV index, light reflection can cause real harm if you do not consistently use sunscreen in winter.
How do I use sunscreen in winter?
Even on cold winter days and dense clouds, UV rays can still reach your skin. Therefore, it's important to apply sunscreen daily to exposed areas such as your face, neck, ears, and the backs of your hands. And don't neglect protection even when you're indoors or near windows, as rays penetrate glass and affect the skin over time.
What is the best type of sunscreen for winter?
Choose a broad-spectrum sunscreen that protects against both UVA and UVB rays and has an SPF of at least 30. These are essential for using sunscreen in winter to protect your skin from damage even on cold days. And since winter weather tends to be dry, it's preferable for the sunscreen to be rich in moisturizing ingredients to keep your skin smooth all day long. If your skin is sensitive, looking for a natural formula free of fragrances and chemicals will help you avoid irritation or redness in the cold.
How often should it be applied?
In daily city life, it's enough to reapply sunscreen every 4 to 6 hours to maintain the required protection. However, if you spend more time outdoors or in snowy areas, be sure to reapply it every two hours, as the reflection of rays from snow or light surfaces increases the intensity of sun exposure even in cold weather.
What are the best sunscreens for winter?
If you're wondering what the best sunscreens for winter are, the best option is usually a broad-spectrum sunscreen (UVA/UVB) with SPF 30 or higher, and rich in moisturizing ingredients to protect your skin from dryness and give it comfortable softness all day long.

Most frequently asked questions about using sunscreen in winter
Is sunscreen effective in winter?
Yes, sunscreen remains effective and important in winter, just as it is in summer. The UV rays that harm the skin do not decrease in intensity with lower temperatures, and they are the main cause of wrinkles, dark spots, and premature skin aging. Therefore, using sunscreen in winter protects you from burns and from an increased risk of skin cancer even on cold and cloudy days.
What causes the sun's rays to be blocked in winter?
Sunlight appears weaker in winter because its angle of incidence differs and the atmosphere is denser, making the rays less bright. However, these clouds or fog do not prevent the passage of UV rays; they only reduce the sensation of their heat. Therefore, you should not be deceived by the cold or cloudy appearance, as the skin is still exposed to these harmful rays.
What is the appropriate temperature for applying sunscreen?
There is no specific temperature that requires applying sunscreen, as its effectiveness is not related to heat but to the UV index. Experts recommend applying it whenever this index is 3 or higher, regardless of the weather or cold. Even on cold days, if the index is high, the skin needs daily protection to maintain its freshness and health.
Using sunscreen in winter is just as essential as in summer. Even with cold weather and weak sunlight, UV rays can still harm your skin. Consistently applying sunscreen maintains its freshness, reduces the appearance of hyperpigmentation and wrinkles, and provides cumulative protection that lasts for years.
