Hello. Made at home, but a big hospital is not necessarily good. The important thing is that you know him well, and it is better to have acquaintances. It is not only cheap, but also guarantees quality. I did it in Daqing Longnan Plastic Surgery Hospital. To be honest, the place is not big, but the effect is good. The silica gel I used is very expensive and I can't take it out in the future. You can make imported silica gel. He will ask you what effect you want before you do it.
