Botulinum toxin is actually the common name of botulinum toxin, which is a type A toxin secreted by botulinum in the process of reproduction and has strong neurotoxicity.
So what is the principle that botulinum toxin can thin face and thin legs? Exercise depends on muscles. After the brain produces instructions, it releases acetylcholine through the nerves and transmits the instructions to the muscles. Botulinum toxin can cause muscle flaccid paralysis by inhibiting the release of acetylcholine, and further cause muscle disuse atrophy. When the muscle volume decreases, the appearance of cheeks will naturally narrow.
How to control the dosage of botulinum toxin injection? Generally, the dose of botulinum toxin should be strictly controlled, and the total dose of each injection is preferably between 200 and 300 units. According to medical literature, if the dose of botulinum toxin exceeds 500 units, poisoning symptoms may occur. More than 2000 units may cause death. It should be noted that even local injection of botulinum toxin can cause systemic problems. Li Wei, chief physician of plastic surgery at Chongqing Emergency Medical Center, said that when there is an overdose of botulinum toxin, symptoms usually appear all over the body. Therefore, in a regular hospital, if you want to hit your face and legs, you will not arrange to hit them at the same time, but in batches to avoid the phenomenon of poisoning caused by excessive dose. Once poisoning symptoms appear, such as general weakness, drooping eyelids, diplopia, swallowing and speech dysfunction or respiratory muscle paralysis, specific botulinum antitoxin can be used for early and adequate treatment.
Finally, who is not suitable for Botox injection? What should I pay attention to when injecting botulinum toxin? Pregnant women, lactating women, patients with myasthenia gravis, people who are known to be allergic to botulinum toxin A and any ingredients in the formula, people with allergies, patients with ptosis, people with extremely thin bodies, patients with heart, liver, kidney and other visceral diseases cannot use botulinum toxin, and patients with injection site infection cannot use botulinum toxin. Don't take aspirin and aminoglycoside antibiotics, such as gentamicin and kanamycin, within 2 weeks before you go to the hospital to inject botulinum toxin. Do not use cosmetics on the day of injection, and do not massage the injection site after injection to avoid the spread of botulinum toxin to other parts.
Therefore, we must be careful when injecting botulinum toxin, and don't overdo it in pursuit of temporary beauty.
