Do you need sunscreen in winter?

　　Sun protection is a must in winter. Among ultraviolet rays, UVA has strong penetrating power and can penetrate clouds and clothing. The intensity of these rays does not decrease in winter. Long-term exposure will destroy skin collagen, causing skin relaxation and fine lines. In addition, snow and ice in winter will reflect a large amount of ultraviolet rays, exposing the skin to double irradiation and making sunburn more likely. In addition, skin oil secretion is reduced in winter, the barrier function is relatively fragile, and the resistance to ultraviolet rays is reduced. Failure to protect yourself from the sun will make skin problems more likely to occur.

How to choose sunscreen scientifically in winter

　　1. Pay attention to SPF and PA values

　　For daily commuting, choose SPF30 and PA++ sunscreen to meet your needs； If you stay outdoors or come into contact with snow for a long time, you need to choose products with SPF50+, PA+++ and above specifications.

　　2. Give priority to mild and moisturizing types.

　　Choose sunscreen with added ingredients such as glycerin and ceramide, which can not only protect you from the sun but also replenish moisture in your skin to prevent your skin from becoming drier and tighter due to sun protection.

　　3. Choose texture according to skin type

　　Dry skin is suitable for creamy sunscreen, which is more moisturizing； For those with oily skin, choose a refreshing gel or lotion sunscreen to reduce greasiness and the risk of clogged pores.

　　4. Confirm that the product is waterproof and sweat-proof

　　When engaging in outdoor activities such as skiing and mountaineering, you need to use waterproof and sweat-proof sunscreen to prevent the sunscreen film from falling off due to sweating or contact with ice and snow, thus losing the protective effect.

　　5. Check the ingredients and avoid sources of irritation.

　　Those with sensitive skin should avoid alcohol, fragrance and other irritating ingredients. You can conduct a skin test behind the ear first. If there is no redness, swelling, itching or other discomfort, use it normally.

　　Sunscreen in winter is an important aspect of skin care that cannot be ignored. Only by choosing the right product and using it consistently can your skin stay healthy even in the cold season. Paired with physical protection such as scarves and hats, the sun protection effect can be more comprehensive.
