No one can stop a woman who loves beauty from pursuing beauty. Girls always want her skin to be whiter, more tender and her face smaller. To put it simply, the medical beauty industry is developing very rapidly now. There are many methods of face-lifting, such as liposuction, face-lifting needle and bone cutting. So what is the principle of these operations?

1, face-lifting method classification

1. Facial liposuction

Facial liposuction, also known as facial liposuction, is to stick a fine needle into the face and slowly suck out excess fat. Doctors can't push too hard. This is a delicate job, which requires a high technical level, just like making facial sculptures, otherwise the beautician's face will look uneven. The operation requires local anesthesia and the whole process takes 40 minutes. Within 3-5 days after operation, the plastic surgeon needs to wear a condom to set the shape, and take out the stitches one week later.

Buy a face-lifting needle

Playing face-lifting needle is to play a biological agent at the hypertrophy of muscle, which makes the muscle relax and atrophy, and reduces the activity and atrophy of masseter muscle. However, the face-lifting needle will fail after half a year and needs to be re-injected. Biological agent is a highly toxic substance, its lethal dose in human body is 2500-5000 units, but only 50- 100 units are used for face-lifting and wrinkle removal, 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 biological agents, the toxicity of the drugs can be enhanced, leading 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.

3. Osteotomy

Osteotomy, also called mandibular angle grinding. This kind of operation requires the general anesthesia of the plastic surgeon, who takes a knife from the plastic surgeon's mouth and smoothes the wide mandibular angle. The operation takes one to two hours, and the cosmetic surgeon can leave the hospital within one week after the operation, and can fully recover after one or two months.

2. Late management of facial plastic surgery

In order to prevent postoperative infection, people should fast for two days after operation, mainly relying on infusion to maintain their physiological needs. After 48 hours, they will start to eat liquid food, such as milk, juice and broth. After 72 hours, they can eat semi-liquid food, such as yogurt, egg soup, rotten noodle soup, porridge and so on. After that, they will gradually transition to a normal diet, but they can't eat hard food or laugh for a month. The patient should not worry about anything during the operation. Postoperative pain can also be completely avoided. At present, it is very important to have an advanced "micropump" analgesic instrument, which can continuously give small doses of analgesic drugs within 48 hours after operation, so that patients can recover in a happy mental state.
