In fact, the so-called slimming needle is Botox, which can achieve the purpose of slimming the face by blocking the nerve conduction of our facial muscles. Perhaps you have heard individual beauty salons or plastic surgery institutions claim that their Botox is new or imported, the effect can be maintained for two years, or even longer; and that Botox face slimming injection three times to be permanently effective, the fact is really so? This is a very good way to get the most out of your life. We know that when Botox is injected into the muscle layer of the human body, it causes a temporary weakening or paralysis of the muscle to achieve the purpose of wrinkle reduction and face reduction, but the body will gradually metabolize this drug. This metabolic process is certain, about 3-6 months. However, it is also possible that the rate of nerve regeneration varies between individuals, and that differences in the effectiveness and maintenance time of Botox treatment occur between people. The average duration of effectiveness of Botox is 3-4 months, which may be slightly extended after several injections, but generally does not exceed one year. There is no big difference between domestic and imported botulinum toxin in terms of efficacy. The real imported brand of botulinum toxin is BOTOX from Allergan. The effect of botulinum toxin is slowly visible, about two weeks to a month after injection; usually after three to six months the effect will slowly disappear, then if you want to get the original effect, you must receive another injection. Even after 3 or more injections, the effect will not be permanent and will disappear after some time. In conclusion, the statement that “Botox will be permanently effective after 3 consecutive injections and no more injections are needed” is untenable. In addition, under certain conditions, botulinum toxin may lead to the production of neutralizing antibodies, and if botulinum toxin type A is used again, there will be no effect, so it is necessary to switch to botulinum toxin types B and F. The way to prevent the appearance of antibodies in the body is to inject a dose of less than 100 units each time and to have an interval of more than 1 month between injections. Although the effect is short-lived, the effect is exact, though it is not true that any fat face type can be slimmed down by Botox treatment. For those fat faces with more subcutaneous fat, facial liposuction or removal of cheek fat pad is needed to solve the problem; while for square faces with large jaw angle bones, bone grinding surgery is needed to do so. When using Botox to remove wrinkles, generally crow’s feet, forehead lines, inner nasolabial lines and neck wrinkles can be removed, but it is most suitable for early and less obvious wrinkles, and the skin is not very loose. If there is significant sagging of the skin, surgical wrinkle removal is required.
