The face slimming needle after a lot of clinical research to prove that it is very safe, belong to the State Food Administration approved the use of products. Recently, many beauty seekers want to understand the “adverse reactions after the face slimming injection” this topic, the following for you to talk about. Face slimming injection common adverse reactions are 4 points: 1, subcutaneous bruising This situation does not require special treatment, generally 3 to 7 days can subside on their own. 2, chewing weakness due to the role of botulinum toxin in the neuromuscular junction, blocking the release of acetylcholine, so that our muscles become relaxed, you chew hard things, you may feel chewing weakness, which is also normal. Generally do not need too much treatment, about a week can recover on their own. 3, concave plug (bite muscle becomes strange) there is a side or both sides of the local have some bulge, because the bite muscle it is a very large muscle, injection due to some improper manipulation may lead to Botox injection uneven, part of the muscle is relaxed, another part of the muscle is not relaxed off, in our facial activities or chewing, it will produce a bumpy situation. When this happens, it is usually observed first, and some of the candidates can recover on their own within a month. If there is no improvement after one month, you can go to the hospital to make up the injection, you can solve. 4, left and right asymmetry (small and large face) before the injection of Botox, you have to assess the candidate, whether the candidate itself exists in the case of small and large face, whether it is caused by bone asymmetry or chewing habits. If the size of the face is caused by skeletal problems, the size of the face may still exist after the face slimming injection. If the muscles are not the same thickness due to muscle movement, the face shape can be modified by adjusting the injection dose of Botox on both sides. If the candidate does not adjust his chewing habits later, the muscle may also reappear asymmetrical face shape during the slow recovery process. Why does someone have a sunken cheek after a face slimming injection? There are two reasons for this phenomenon, one is the point of playing too high, and the other is caused by too high a dose. This has a lot to do with the skill level of the doctor, which is why I always recommend that candidates go to a regular hospital to receive plastic surgery. But the facial depression after this symptom, seekers should not worry too much, thin face injection is not irreversible, through the body metabolism, the effect of thin face injection will gradually disappear, the cheeks will slowly recover.
