1.What is Botox? Is it toxic? Botulinum toxin is not as scary as its name suggests. Many beauty places call it biological wrinkle removal, or genetic wrinkle removal, in order to eliminate people’s fears. Botox for cosmetic injections is a biological toxin that works by paralyzing local nerves, blocking the contact between the nerves and the muscles so that the muscles no longer contract, thus making the wrinkles disappear. When used properly, Botox is not really as “toxic” as its name implies and is commonly used in neurology, ophthalmology, plastic and cosmetic surgery. People have been injecting Botox for more than 20 years, and the current dose is only one percent of its maximum safe dose, so it is very safe. 2, adhere to the injection can keep 10 years not old? Botulinum toxin has a shelf life of about six months to a year, after which it is metabolized by the body, and the shelf life varies according to the physique of different people, which means that people who rely on Botulinum toxin to remove wrinkles have to be injected every six months or once a year in order to continuously remove wrinkles. American authoritative experts have conducted a comparative study on the treatment of Botox on a pair of twins, and confirmed that long-term continuous injection of Botox can indeed delay aging to a certain extent and effectively keep the face. 3.Why is Botox used to treat enlarged bite muscles? Why is Botox used to treat bite muscle hypertrophy instead of removing the muscle directly? Women with oval shaped faces are often asked for plastic surgery because of the enlarged jaw angle. Every year, tens of thousands of cases of jaw angle curvilinear osteotomy are performed. More than 90% of these patients are accompanied by benign bite muscle hypertrophy and wish to have it reduced at the same time. Since it is difficult to grasp the amount of muscle excision and the depth of muscle excision during surgery, not only is the result unsatisfactory, but it also tends to increase the chance of bleeding, hematoma, and infection, resulting in serious complications such as asymmetry on both sides of the face, facial nerve paralysis, dental closure, and longer-term muscle spasm. In 1994, Smyth et al. reported the use of botulinum toxin for the treatment of bilateral facial hypertrophy. In 1994, Smyth et al. reported their experience with the use of botulinum toxin in the treatment of bilateral bite hypertrophy, which was considered a revolutionary new method, and Smyth recommended this technique as a routine treatment for “chewing muscle hypertrophy”. Botulinum toxin injections shrink and reduce the size of the bite muscle through denervation, making the treatment more complete and solving this problem, and increasing the patient satisfaction rate and the number of patients seeking treatment. The combination of Botulinum toxin injection and jaw angle surgery has obtained a good effect of 1+1 is greater than 2 in the treatment of fat face. Combined with facial liposuction, cheekbone reduction and widening, the fat face can be improved to a greater extent. 4.How is Botox used? Generally 1-5 injection sites are selected on each side for injection. The injection should be done as slowly as possible, and there is no need for local massage and other special treatment after the injection, which takes only a few minutes. 5.When does Botulinum toxin type A take effect? How long does the effect last? Two weeks after the injection of botulinum toxin type A into the bite muscle, the patient can feel a decrease in chewing power when chewing hard, and there is no obvious bulge and fatigue in the bite muscle, and there is no obvious contraction of the bite muscle when touched by hand locally. Generally, the atrophy of the bite muscle and the change of face shape can be observed 1 month after the injection of type A botulinum toxin. The effect can generally be maintained for six months to one year. 6.What adverse reactions may occur? As a muscle injection drug, Botox has no significant side effects and has more advantages than traditional surgical methods. Local adverse reactions after Botulinum toxin type A injection mainly include excessive weakness of the occlusal muscles and the corresponding manifestations caused by the spread of Botulinum toxin to the adjacent muscle tissue, and these clinical manifestations are related to the injection site and the dose of Botulinum toxin injected. Individual patients have been found to have fever, discomfort, and fatigue after botulinum toxin injection. Generally, these clinical manifestations are transient and disappear on their own within a few weeks. 7.Will there be recurrence after treatment? After botulinum toxin is injected into the bite muscle, the effect can generally be maintained for about 6-8 months, and the bite muscle will gradually recover after the drug effect is lost. However, after multiple injections, the effect will last longer and longer, and can generally last about 1 year after 3-4 times, and a few people can maintain the effect of bite muscle even without injections in the future. Botulinum toxin can be repeatedly injected and will not produce toxin accumulation. 8.What other methods are available for the comprehensive treatment of fat face? Besides botulinum toxin injection and jaw angle curved osteotomy, there are also facial liposuction, cheekbone reduction and widening methods. Combined treatment can make a big improvement of fat face.
