I'm not sure if it hurts because I've been under anesthesia for a long time, but it's bearable. If you're someone who cares about your face and is sensitive, you should definitely go to a place that does it well. The lumps and see-throughs were very visible at first, so I was very stressed until the swelling went down. I got a domestic product, but it was my first time, so I couldn't get it for almost a week. I went there and it all fell out. The corners of my mouth are the same as before. I recommend going to a hospital that will retouch it. If you don't retouch it, you will have to pay almost the same price and get it again.
