It is said that applying an appropriate amount of sunscreen frequently at regular intervals before going out is more effective than applying a large amount all at once. In the hot summer, when sweating, Since there are many situations where it comes into contact with water, the sunscreen may wash off, so it is recommended to reapply it every 1-2 hours. Since sunscreen does not last long after a single application, please be sure to carry it with you and reapply every hour on days with strong UV rays to protect your skin!
