I made a reservation at Seomyeon Ppeum Hospital to go to a hospital that allows same-day reservations . I had the procedure done at other hospitals with Gold PTT, so I didn't feel any resistance, but I feel like I wasted money without checking properly. For those who are getting the procedure for the first time , please check whether the place divides the ampoule and uses only half a bottle or throws away the entire bottle before getting the procedure . They didn't even check when it was opened.. When I first saw the ampoule bottle and asked if someone else was using it, the management office said that it was hospital policy and they didn't know, so I asked the doctor who did the laser, and he said that since it was done at the management office, he didn't know^^.. Then, when I asked if the ampoule for other procedures was divided like this, the management office asked what was divided and used, so I didn't ask any more questions. I'm still confused because the doctor who did the procedure didn't know how the ampoule was managed or how much was used. I'm sure everyone has a lot of concerns about acne, so please check and definitely go to a specialized hospital..
