Ultraviolet rays are the direct culprit for melanin precipitation, skin blackening, black spots and wrinkles. Therefore, the simplest and most basic method is to minimize UV rays.We should try our best to do the following:
1. Avoid exposure. Try to avoid the strongest sunshine from 10 am to 3 pm, as well as stay away from the beach, the top of the mountain, etc.
2. Carry an anti-UV umbrella, hat, sunglasses and long-sleeved clothes in cotton and linen. But these can only block a part of the ultraviolet rays, and the parasols and sun hats cannot block the ultraviolet rays reflected from the ground.
3. Use sunscreen properly.
