Face-lifting beauty, whether liposuction, injection or bone cutting, has great risks. Before choosing cosmetic surgery, beauty seekers must know the surgical methods and risks in detail, and then choose carefully.

Botulinum toxin is injected into muscle hypertrophy, which makes muscle relax and atrophy, and the activity of masseter muscle decreases and atrophy. However, the face-lifting needle will fail after half a year and needs to be re-injected. Botulinum toxin is a very toxic substance. Its lethal dose in human body is 2500~5000 units, but it is only 50~ 100 units, accounting for only 1% ~ 2% of the lethal dose. However, if the beautician is taking other drugs, such as gentamicin and penicillin, during the injection of botulinum toxin, it can enhance the toxicity of the drugs and lead to poisoning of the injector. Some unqualified "beauticians" in life beauty salons often have drooping eyelids, drooping eyebrows and local swelling because they are not familiar with anatomy, the injection site is not allowed, or the concentration and dosage are too large. Some people even have diplopia after receiving the injection. If you hit your face too much, you may have difficulty swallowing. Therefore, it must be operated by a professional cosmetic doctor to ensure safety.

If the injection is excessive, some parts that should not be paralyzed will be paralyzed, and the muscles of the lighter will be weak, and even the strength to eat melon seeds and peanuts will not be available. In severe cases, they will have difficulty breathing.
