Each injection takes about an hour, but it will vary according to individual circumstances. Doctors need to adjust according to the situation, and the effect will vary according to individual physique. My aunt played in Beijing Ximeisi CMS International Plastic Surgery Center some time ago, and the effect was very good. The whole thing is the feeling of natural whitening. She looks very young, healthy and beautiful ... Aunt also said that Simesi's service attitude is also excellent.
