I had to go to the silpop puller hospital... but the hospital was too far away, so I just unwrapped it with scissors at home by myself~! I disinfected it and it took about an hour to remove it...but it didn't hurt~!I heard that if I do it wrong, it will leave a scar..It seems to be fine so far!! On the second day, I washed my face! But maybe it's because I washed my face..It seems like it's been since I unscrewed the thread/ The wound is itchy and convex and convex like hives . It wouldn't be a side effect ......
