If you want to get a more lasting and natural effect with the face-lifting needle, generally add a second needle 3-6 months after the first needle, and add another needle every six months or so after the second needle, so that the effect of the face-lifting needle can be maintained for a long time without continuous injection, because after three face-lifting needles, the masticatory muscles will automatically lose weight, and everyone will change the habit of refusing, and the lost masticatory muscles will not get fat again.
