Whether it is cloudy or rainy, staying outside for a long time (in the open air) will make your skin black, or because there are ultraviolet rays in the sun. On cloudy or rainy days, although the delamination blocks the sunlight, the ultraviolet rays are destroyed by the A-section (long wave) line. Protective measures should be taken when going out, such as wearing a hat, umbrella, sunglasses or applying sunscreen. 10 the morning to 3 pm is the most stressful time of the day. Try to avoid going out in the sun during this time, even if it is cloudy or rainy. When there is sunshine, you can still distinguish the ultraviolet radiation range, which is easy to avoid. You can't see where there is ultraviolet light on cloudy days, which often makes people ignore the effect. Therefore, we should pay attention to avoid purple operation on the skin during the day.
