However, it should be noted that if you stay in the water world for too long, or frequently touch the sunlight reflected from the water surface, it may still cause ultraviolet damage to your skin. Therefore, it is suggested that you should protect your skin moderately when you go to the water world at night, such as wearing sunscreen, hat and long-sleeved clothes. In addition, it is best to avoid exposure to the sun for a long time when the sun is strong, which can better protect the skin.
