Because it is a factory type, it is difficult to designate a doctor in charge. I chose Rejuviel, and the first treatment was 0.5 on each side of the nasolabial fold (cannula treatment). The doctor recommended 0.5 on each side as a point, so I had an additional needle treatment. A total of 2 cc was performed. It's a shame , but I think it looked prettier with a little less. However, when I went to the doctor because I thought I had an infection, I was able to meet and receive treatment with the doctor who performed the procedure, and I was able to check the progress afterwards.
