However, I heard that a friend who had injected a face-lifting needle at bK Toyo Surgery and Plastic Surgery Hospital in South Korea said that it is very particular to choose a point on the face when injecting a face-lifting needle, and it is not enough to inject a needle at a similar position. Experienced and skilled professional doctors must first find the right position, sometimes two or three positions, and sometimes the number of needles to be injected will not be exactly the same, so that the effect after injection will be very good and obvious, and it will last for a long time. There will be no adverse reactions. Only then can I know why some people have a particularly good effect, and some people will feel uncomfortable because they have also been injected with a face-lifting needle.
