외출 30분 전에 발라야 하는 군요 좋은 정보 감사합니다!
I use a lot of sunscreen in the summer.
It is recommended to use sunscreen within 12 months of its expiration date.
Generally, the recommended duration for sunscreen is 4 hours. Please reapply before 4 hours have passed.
It is recommended to apply sunscreen 30 minutes before going out.
