First, pay attention to sun protection! Whether it is cloudy or sunny, there will be ultraviolet rays. When ultraviolet rays are irradiated for too long, the skin tends to turn black. 10 Morning to 3 pm is the most stressful time of the day, so try to avoid going out during this time.

Second, pay attention to skin repair. In addition to sun protection, skin repair and protection can not be omitted.

Third, eat more fruits and vegetables, especially fruits rich in vitamin C, such as tomatoes, strawberries and peaches.

Fourth, pay attention to rest and sleep. Long-term lack of sleep will not only affect health, but also slow the blood flow of the skin, shrink the blood vessels, make the blood stagnate into spots, and turn the skin into gray-black.
