If you want to do some anti-aging projects, I recommend you to go to a hospital where I used to work, Japan Free Mountain Beauty and Plastic Surgery Hospital. I went to see Dr. Takashi Taniyama for catgut embedding. Dr. Gu Shan's technique is very delicate. Although the face was anesthetized, I still felt that the angle and depth of thread insertion were different. After I finished, I could see the improvement effect visible to the naked eye, and then I recovered quickly.
