According to the explanation, it is effective from 3 weeks to a month, and I heard that there may be swelling in the beginning, but there was no swelling, but it was immediately after the procedure that I felt that my eyes had become a little slimmer. It's been two months now, and I thought the effect would last to some extent for the first month, but now it seems to have returned to its original state... I can't tell the exact difference between weight gain and lifting... I know you only need to get it once a year, but next time. If you get it, definitely sleep... ㅠㅠ
