In winter, the weather is cold but UV rays are still strong, the skin needs more care.
According to Dr. Le Thai Van Thanh, Skin Care Clinic, University of Medicine and Pharmacy Hospital, Ho Chi Minh City, whether the weather is hot, cool or cold, we are still affected by UV rays. To protect the skin in the cold season, sunscreen is necessary in addition to moisturizer and anti-chapping cream.

Doctors say that UV rays are weaker in winter, so they do not cause burning sensations like in summer. However, UVA rays account for more than 90% of UV rays and are strong all year round, causing skin to age quickly, wrinkle and cause skin cancer if exposed for a long time.
In winter, the skin is often sensitive, dry, chapped and lifeless. We need to drink more water, supplement fiber, vitamins and apply sunscreen to limit the skin's direct exposure to the outside environment.
In addition, the ozone layer, which blocks harmful ultraviolet rays,ialso becomes thinner in winter. Therefore, sunscreen is a simple and safe way to protect the skin, especially for women.
Dr. Thanh advises that using sunscreen also depends on the level of exposure to sunlight in a day. Note to choose sunscreen with the appropriate SPF index. The best time to apply cream is about 15-20 minutes before going out and reapply after two hours of use. In addition, you should also cover up fully to have healthier skin.
However, you should also note that if your skin is not exposed to sunlight, your body will lack vitamin D - a factor that helps absorb calcium for strong bones.
