I went to get the ㅇㅂㅈㅇㅇ Rejuran Healer, and since it was a factory-type place, I don't remember the doctor's name well. Here, after anesthetizing your face, they directly inject it with a hand injection. They injected Rejuran with a hand injection, but I think they did it wrong(?) and it splashed on my face... They didn't seem to have much experience and the effect was minimal, so I don't recommend...
