With more and more beauty lovers expecting to achieve cosmetic results through minimally invasive and minimally cosmetic ways, “face slimming injection” is sought after by everyone. So, what is a “face slimming injection”? Why can it slim your face? What should I pay attention to when I inject the “slimming needle”? The following to answer your questions and solve the problem. Principle: The so-called “slimming needle”, in fact, is the type A botulinum toxin injection (domestic use is mainly the United States Botox and domestic Hengli two brands). Botox is an extracellular toxin secreted by the bacterium Clostridium botulinum, divided into seven types from A to G. The most toxic and most commonly used are type A and type B. Botox can block the nerve impulses between nerves and muscles, allowing over-contracted muscles to relax, paralyzing over-developed muscles and gradually atrophying and reducing the size of muscles. Indications: People with enlarged bite muscles. Botulinum toxin injection of the bite muscle, to solve the bite muscle hypertrophy caused by the following too wide, in order to improve the face shape, to achieve the purpose of slimming the face. Contraindications: 1, pregnant and lactating women 2, patients with neuromuscular dysfunction, such as those suffering from amyotrophic lateral sclerosis, myasthenia gravis 3, very thin body, heart, liver, kidney and other systemic diseases 4, allergic body 5, local infectious lesions Precautions: Before injection: 1, avoid menstruation 2, 1-2 weeks before surgery do not take aspirin, aminoglycoside antibiotic drugs (such as Gentamicin, kanamycin, streptomycin, tobramycin), because they will enhance the toxicity of botulinum toxin type A. 3, do not wear makeup on the day of injection After injection: 1, botulinum toxin injection after face slimming in the hospital to observe 30 minutes, no discomfort before leaving the hospital 2, the injection area within 6 hours do not touch water 3, do not strenuous exercise within 24 hours 4, a week of spicy stimulus seafood and hard shell food, avoid smoking and alcohol 5, a week 6.In order to maintain the effect, you can re-inject after six months. Frequently Asked Questions: 1.Is it safe to inject botulinum toxin into the face? Are there any side effects? The current dose of Botox is less than 5% of its maximum safe dose, so it is very safe. In the case of reasonable application and correct operation, botulinum toxin injection for face slimming is no side effects. 2, botulinum toxin injection face slimming effect can maintain how long? General injection 1-2 weeks after the effect began to appear, 2-3 months the best effect, about 6 months effect disappeared. Botulinum toxin injection slimming effect is not 100%, if the short-term repeated injection (< 5 months), injection dose is too large, or due to improper injection into the blood, the body will appear anti-botulinum toxin antibodies, making injection slimming effect is greatly reduced. 3, several consecutive injections of botulinum toxin can be permanently thin face? No. After entering the body, Botox blocks the nerve impulses between the nerve and the muscle, and the bite muscle is temporarily weakened or paralyzed, making the bite muscle shrink and become smaller. However, the body will gradually metabolize this drug, and the muscle will regain innervation and gradually regain its form and function. Therefore, it is impossible to achieve permanent face slimming through Botox injection. 4.Will it "bounce back" after stopping Botox? The so-called "rebound" is only after stopping Botox, the bite muscle will return to its original size (before Botox injection), but it will not be bigger than before the injection. If you want to maintain the effect, you need to inject again after six months. 5.What are the advantages of Botox injection and jaw angle surgery? For the jaw angle hypertrophy caused by the lower part of the wide (bony square face), only with the help of jaw plastic surgery, jaw angle osteotomy or with part of the bite muscle removal, the post-operative effect is long-lasting, but the surgery requires general anesthesia, relatively large intraoperative trauma, bleeding, long recovery time. For the simple bite muscle hypertrophy caused by the following wide (muscular square face), through the injection of botulinum toxin action on both sides of the cheeks of the bite muscle, so that the hypertrophy of the muscle temporarily atrophy, become smaller, so as to achieve a thin face, the operation is more simple, minimally invasive, the disadvantage is the need for long-term injection. 6.Will botulinum toxin become addictive? Botulinum toxin drug itself is not addictive, the psychological dependence of the applicant is often the reason for injection "addiction".
