Botox face slimming is very popular among the Asian population, especially among young women. The mechanism of action of Botox is simply to block the nerve conduction that controls the bite muscle, resulting in a decrease in the strength of the bite muscle, and after a period of time (usually one week to start to show a reduction in the size of the bite muscle). Currently, there are only two types of botulinum toxin allowed to be marketed in China. American Botox and Chinese Hengli. The biggest difference is that Botox has been tested in a series of diffusion range of about 0.8cm, Hengli has not done similar rigorous testing, may be a slightly larger diffusion, in addition to the price difference. For face slimming injections, generally for the first time, we take into account the expectation of the candidate to be able to achieve visible results, generally 100u injection. Serves to recommend an interval of 4-6 months before the second injection, the second injection needs to be adjusted, for some sensitive candidates, may need to adjust the measurement. The third injection we recommend an interval of 6-8 months, generally after the first two treatments, the effect is more obvious. The third time we can further adjust the measurement and injection points to achieve good results in combination with the customer’s requirements. Generally speaking, after the completion of 3 times, we can achieve a relatively constant effect for a period of time. Even if the injections are repeated in the future, the interval will be longer and longer. In addition, I would like to tell you a few precautions about Botox injections for face slimming: Over the age of 40, candidates for face slimming still need to be a little cautious, because the decrease in muscle tone may lead to sagging of the soft tissues of the face. Do not deliberately pursue a small face or ask to play all a bottle of drugs, sometimes too thin is not good. Do not inject too often, injections within 3 months may produce antibodies, leading to the lifelong ineffectiveness of the drug.
