Do You Need Sunscreen in Winter ?


Although the weather is cold in winter, it does not mean that the intensity of the sun will weaken. In fact, winter sunlight still contains ultraviolet (UV) radiation. Although these ultraviolet rays may not be as intense as in summer, they are still potentially harmful.

During the winter, the Earth’s orbital position places much of the northern hemisphere farther from the sun, resulting in lower winter sunlight radiation angles. This means that sunlight has to travel through a longer layer of the atmosphere and is scattered and absorbed to a greater extent. Despite this, winter sunlight still contains two main types of ultraviolet rays: UVA and UVB.

  1. UVA ultraviolet rays: UVA is a type of long-wave ultraviolet rays with strong penetrating power and can penetrate clouds and glass. It causes long-lasting damage to the skin and is one of the main factors causing skin aging and skin cancer.
  2. UVB ultraviolet rays: UVB is a medium-wave ultraviolet ray with weak penetrating power. It mainly affects the surface layer of the skin and is one of the main factors causing sunburn, solar dermatitis and skin cancer.

Although ultraviolet radiation in winter is relatively weak, the intensity of ultraviolet rays increases when reflected from the snow, making the skin more susceptible to damage. Therefore, even in the cold winter months, sun protection is still necessary.

Skin Protection Needs in Winter

Winter skin is often affected by dry, cold weather and indoor heating, so it needs special protection and care. In such an environment, the skin is more susceptible to UV damage, so sun protection measures become particularly important.

Dry environment: The humidity in the air is low in winter, which can easily lead to dry skin. Dry skin is more susceptible to UV damage and needs extra moisturizing and moisturizing.

Cold weather: Cold weather can make the skin fragile and susceptible to damage. In cold weather, the skin’s barrier function weakens, making the skin more susceptible to UV rays.

Indoor heating: Indoor heating can dry out the air, further exacerbating dry skin problems. Dry skin is more susceptible to UV damage, so it needs more moisturizing and moisturizing.

Why You Need Sunscreen in Winter ?

UV rays are still around: Even on cloudy or cloudy winter days, UV rays can still penetrate clouds and reach the surface. Even if the heat of the sun is not felt, UV radiation is still present and can cause damage to the skin.

Snow Reflection: During the winter, snow is highly reflective of sunlight, which means that even if you are not directly exposed to the sun, you will still be exposed to UV rays while standing on the snow. In this case, the exposed area of skin increases and the risk of damage increases accordingly.

Indoor light: During the winter, people tend to spend more time indoors. However, many indoor light sources (such as lamps and computer screens) also produce some level of UV radiation, which can also affect the skin.

Weakened skin resistance: The cold and dryness of winter can weaken the skin’s barrier function, making the skin more fragile and susceptible to damage. At this time, the damaging reaction to ultraviolet light may be more obvious.

The Importance of Sun Protection in Winter

UV rays are stronger in winter
Many people think that the sun’s rays become smaller in winter, so they don’t need sunscreen. In fact, what really damages our skin is ultraviolet rays. Moreover, after winter, the content of the ozone layer will decrease. At this time, ultraviolet rays will be more intense than in summer and more harmful to the skin. If you do not use sunscreen, your skin will age more easily.

Winter sunscreen can repair dry skin
Winter sunscreen generally has stronger repairing power, so if you insist on wearing sunscreen in winter, it can strengthen the elasticity and toughness of skin fibroblasts, strengthen and repair skin tissue, and improve dry skin.

Sun protection in winter can keep fair skin tone
People who want to whiten their skin should pay special attention to sun protection in winter. Don’t think that you can take it lightly in winter. If you don’t use sun protection in winter, your skin will be easily affected by ultraviolet rays and slowly turn dark. Then the fair skin that has been maintained all summer will also be damaged in winter. Defeated, so if you want to keep your skin white, you must pay attention to sun protection in winter.

Skin metabolism slows down in winter
When the weather gets colder and enters winter, the skin’s circulation metabolism will slow down, thus weakening the skin’s self-renewal and repair functions. If you don’t use sun protection in winter, your skin will be affected by ultraviolet rays and produce melanin, which will be difficult to discharge and eventually form spots.

Winter Sun Protection Tips !!!

Although the sun is weaker in winter, sun protection is still essential. Although ultraviolet rays in winter are not as strong as in summer, they are still potentially harmful and may cause sunburn, tanning, skin aging and even skin cancer. Therefore, sun protection in winter is equally important. We should take appropriate sun protection measures, including choosing appropriate sun protection products, using sun protection products correctly, avoiding direct sunlight, and wearing sun protection clothing during outdoor activities. With the right sun protection, we can keep our skin healthy and youthful and enjoy a great winter.
