Almost every candidate who comes to my clinic for help with face slimming asks the same question: Is it better to use imported Botox or domestic Botox? Here I share with you my experience in my long-term clinical work on this item of face slimming. Domestic botulinum toxin (Henley) and imported botulinum toxin (BOTOX), are A-type botulinum toxin, injected with the same mechanism of action to slim the face, by inhibiting the release of acetylcholine from motor nerve endings, so that the muscle fibers of the facial bite muscle can not contract, thus achieving the purpose of disuse atrophy. Hengli and BOTOX are both 100IU/bottle for face slimming injection, the dosage of both is the same 100IU, so what is the difference between the two for face slimming? The price of domestic botulinum toxin (Hennessy) is cheaper and generally acceptable to the majority of beauty seekers, so for particularly fatty bite muscle and thin calves such as the application of a larger amount of more than one bottle of the case, domestic botulinum toxin is a good choice. However, due to the production process and other reasons, compared to BOTOX, the impurities contained in it are relatively more, and the duration of action is shorter compared to BOTOX. Imported botulinum toxin (BOTOX) has high purity, low impurity content, and repeatedly injected, the body is not easy to produce antibodies to it, so its effect is more lasting after injection. The price of BOTOX is higher, in terms of face slimming alone, an injection dose and domestic botulinum toxin is the same, are a bottle. But face slimming injections generally need to be injected more than 3 times to achieve a more lasting effect, so the overall cost is more expensive than Henley. To conclude, BOTOX and Hennessy are safe and effective face slimming needles, the beauty seekers can choose according to their own situation. Of course, the injection treatment must choose the regular medical channels, so as not to use unqualified products, plastic surgery into disfigurement Oh.
