Experts from Shijiazhuang Xingyuan Plastic Surgery Hospital will tell you! ? Yan Kun, director of Shijiazhuang Xingyuan Plastic Surgery Hospital, said that there may be slight swelling, pain or numbness within a few hours after the face-lifting injection, and the cheeks may look a little red. Others have no obvious symptoms. In addition, in a few days, due to the paralyzing effect of botulinum toxin, the masseter muscle will shrink somewhat, which will lead to chewing fatigue. At the same time, the expression on the mouth may be unnatural, which is a normal temporary phenomenon, so don't worry. As long as the relevant taboos are handled according to the doctor's advice, these normal reactions will soon disappear on their own. About a month later, the face-thinning person can find the atrophy of occlusal muscles and the change of facial appearance. In addition, the effect of face-lifting needle can last for about one year. After that, with the weakening of drugs, masseter muscle hypertrophy may recover. If you want to keep the face-lifting effect, you can inject it again. ? ? 0? 2? 0? 2
