It's been two months since I finished the face-lifting needle. Why is my face still stiff?
The stiff expression after face-lifting needle may be caused by these aspects: 1, the normal reaction after normal operation. After injection of botulinum toxin, the muscle strength of masseter muscle is weakened, which will lead to unnatural facial expressions. This is a normal injection reaction. This unnatural expression can appear as early as 24 hours after injection, and the peak of action is 7- 14 days after injection, and the expression returns to its original state after 2-8 weeks. 2. The position of botulinum toxin is biased. When using a face-lifting needle to face-lift, doctors are required to accurately inject botulinum toxin into two points on one side of the face: the first point is located in the most obvious part of the masseter muscle (confirmed and marked after observing with teeth relaxed); The second point is located diagonally above the first point and is more than 1cm away from the first point. Any deviation between these two points will cause abnormal facial expression stiffness, and this stiffness will last for more than 8 weeks. 3. When the injection position of botulinum toxin is too shallow, the doctor must inject botulinum toxin into the masseter muscle to achieve the effect. However, if the doctor does not have a solid grasp of the anatomical level and injects botulinum toxin into the upper muscles, it is likely to damage the facial nerves and cause abnormal facial expression. The common manifestations are drooling, mouth slanting to one side and involuntary twitching of the corners of the mouth, which may even last for several years. 4. Overinjection of Botulinum Toxin Generally speaking, it is relatively safe to inject Botulinum Toxin less than 100 unit each time in medical beauty. Botulinum toxin is injected into both masseter muscles, which will not exceed 100 unit. If your doctor is very irresponsible to meet your urgent wishes, your expression may be extremely stiff for more than 8 weeks. 5. The interval between two injections is too short. In order to ensure a better face-lifting effect, botulinum toxin can be treated for many times, but the time of each treatment should not be less than 1 month. If you are crazy enough to inject botulinum toxin many times a month, your expression is unnatural, unfortunately, your expression will last for a lifetime. 6. After injecting botulinum toxin, the doctor will tell you not to massage by hand, because when you massage by hand, the botulinum toxin liquid that has entered the masseter muscle will penetrate into the adjacent expression muscles, thus aggravating the unnatural expression. In this case, the expression will return to normal for more than 8 weeks. In addition to these factors, the duration of facial stiffness after botulinum toxin injection is also related to the physical quality and masseter structure of beauty seekers. As long as you choose a regular medical institution, most beauty seekers don't have to worry about stiff facial expressions. But you probably can't tell whether your facial stiffness is caused by normal injection reaction or facial nerve injury, so you can choose to go to a regular medical institution when facial stiffness lasts 1 week. Finally, I would like to remind you that the face-lifting effect of face-lifting needle lasts for a short time, usually only 3-6 months. Therefore, you'd better not expect too much about the face-lifting time after the face-lifting needle.
