Well, the injection effect is good, but it is too easy to rebound. You played well, and it took two years to rebound. Generally, it needs to be injected two or three times a year in China, which is very troublesome. If you can, I suggest you go to Korea again. In addition, there is an ultrasonic face-lifting method in China, and the effect is good. It can be used for 5 to 10 years at a time, and the price is not expensive. Please check it when you have time.
