Botulinum toxin was discovered in the 1960s and started to be used in medical treatment in the 1980s, early on for the treatment of muscle spasticity, such as: squinting neck deformity, strabismus and so on. Subsequently, as it was found to be effective in reducing wrinkles after injection into the skin, it became unstoppable and is now widely used in the aesthetic medicine industry as a gospel for the majority of beauty lovers. Is it safe to inject Botox? The most important type of botulinum toxin is type A (all the botulinum toxins mentioned in this article are of this type). Although botulinum toxin is highly toxic, its toxicity is greatly reduced after dilution and can be used in medical services. The commonly used medical botulinum toxin is one part per million of the lethal amount in humans, which is very safe. Of course, the premise must all refer to regular products, illegal and shoddy botulinum toxin may be harmful to the human body due to a variety of factors such as purity and dosage, with fatal consequences. Is botulinum toxin the nemesis of all facial wrinkles? The wrinkles on the human face are roughly divided into: gravitational wrinkles and power wrinkles. Gravitational wrinkles are mainly wrinkles caused by gravity and skin relaxation, such as the wrinkles in the nasolabial folds and nasofacial grooves, commonly known as decreases. For this kind of wrinkles, Botox is hardly effective to improve them. Power wrinkles are skin folds produced by the movement of facial muscles, typically forehead lines (head-lift lines), inter-brow lines (Kawasaki lines), nasal heel lines, corners of the eyes (crow’s feet), perioral lines, etc. For power wrinkles that just appear and are not serious (no dead folds are produced), Botox treatment is a good choice. Fourth, the shortcomings of Botox injection: Botox injection has the advantages of small damage (local injection can be), fast results (2-3 days after injection can be seen), easy operation (the injection process is usually less than 10 minutes), but of course, just as there is no perfect person in the world, Botox also has shortcomings. 1. First of all, the maintenance time is limited, and it is not permanent. It usually lasts from 3-8 months, and is related to Botox itself, injection site, dosage and method, as well as individual differences of patients and other factors. Therefore, it usually needs to be injected 2-3 times a year to achieve the best maintenance effect. 2. Another problem that arises after Botox injection is unnatural facial expression. Facial muscle activity is a complex group activity, a simple smile may require the synergy of several muscles to complete. Therefore, when a particular muscle is not involved in the activity, it may cause an uncoordinated movement and give an unnatural look. However, fortunately, due to the shortcomings of Botox, this unnaturalness can be slowly restored. V. What are the qualified Botox products? At present, the regular imported products are mainly: Botox produced by Allergan and Dysport produced by Ipsen. The only domestic botulinum toxin in China is the “Hengli” brand therapeutic botulinum toxin type A produced by the Biological Research Institute of Lanzhou City, Gansu Province, which has a national drug production batch number and is a regular legal product. Because Botox is a toxic drug, it needs to be managed by qualified institutions, and individuals cannot buy, sell or store it, so the quality and effect of Botox obtained through personal channels cannot be guaranteed, and may even have serious consequences. Botox injections need to pay attention to what 1, botulinum toxin injection has the advantages of small damage (local injection can be), fast results (2-3 days after injection can be effective), easy to operate (injection process is usually less than 10 minutes), but the maintenance time is limited, generally ranging from 3-8 months, so usually need to be injected 2-3 times a year to achieve the best maintenance effect 2, before the operation: the skin must be kept clean, healthy There is no infection. No systemic diseases, no immunosuppressants, anticoagulants and other special drugs are being used. 3, after surgery: avoid hot water bathing for a short period of time; avoid alcohol, tobacco, spicy, stimulating; stop using cosmetics; do not do frequent expression sports. Six, the consequences of greed: the right amount will make people younger and more beautiful, with excessive can be hey hey hey hey… Finally, biological aging is irreversible, Botox injections can slow down the process to a certain extent, but do not be greedy yo! At the same time, botulinum toxin injections require a particularly high level of skill on the part of the doctor, and the candidate must choose a regular medical beauty hospital and an experienced doctor. The Department of Aesthetic Plastic and Burn Surgery at West China Hospital routinely injects Botox, and welcomes all beauty seekers to visit.
