Polyacrylamide gel injection for breast augmentation was banned by the State Drug Administration, three ministries and commissions jointly investigated and dealt with three manufacturers producing fake botulinum toxin for wrinkle removal, stem cell injection beauty scam was exposed, and beauty salon injections were repeatedly exposed by the media …… Recently, within the medical beauty industry, there has been a series of consecutive worrying events and has caused some concern in the society. Thus medical cosmetic practices by injection were widely suspected, and some beauty seekers became extremely frightened of injections. Emerson said: Health is the first priority of life. The beauty of the damage to health is not worth advocating, but the sacrifice of partial or temporary health in exchange for a beautiful appearance is the choice of many cosmetic surgery is difficult to avoid, and the proper use of injection is precisely a medical beauty means of less damage. 1, injectable beauty safer Although injectable breast augmentation has been abolished, but this does not mean that the injection method itself is dangerous, it should be said that the development of safer and more effective injection materials, is still the direction of the development of the cosmetic surgery industry. The injection method as an important means and method of cosmetic surgery is still very useful and has been confirmed and long-term practice to confirm its safety and effectiveness. (1) Injection therapy for keloid scars: For keloid scars and keloid-like hyperplastic scars, corticosteroid injections within the lesioned tissue are still the preferred method in many human sites. (2) Injection therapy for hemangioma: Strawberry hemangioma and some spongy vascular malformations seriously affect the appearance and function, and injection of appropriate sclerosing agents and anti-tumor drugs is the main treatment and an important surgical adjunct. (3) Facial injection wrinkle reduction: For dynamic wrinkles on the face and neck produced by expression, injection of botulinum toxin type A is the preferred method, but this method has certain complications and is generally more transient. For deeper static wrinkles on the face, injectable fillers are available. The two methods can also be used in combination for better results, and it is important that the drugs and materials used must be safe and legal. (4) Facial depression filling: including wrinkles, lip augmentation, improving facial contour, filling depressed scars, in addition to the available solid materials, the injection method still has a great role to play. (5) Granular autologous fat injection free transplantation: This is a structural autologous transplantation at the tissue level, which is a classic method for facial filling depressions and breast augmentation, but it also has shortcomings that have not yet been overcome, mainly the absorption rate after surgery is difficult to control and predict, the surgical process, especially the handling of fat tissue is tedious, and the amount of single tissue transplantation is limited, but it is still a safer way of filling. In the future, if growth factor slow release technology and fat stem cell technology can be applied, there will be considerable potential. (6) Growth hormone HGH injectable supplement: HGH is the main component of sheep placenta except for sex hormones, and its main cosmetic effects are to reduce 14.4% of the body’s adipose tissue, increase 8.8% of lean body tissue, improve skin texture, and increase immune function. HGH has been used as an exogenous hormone supplement with therapeutic effects, and the latest research shows that it has certain efficacy in facial rejuvenation and body building, with the disadvantages of a longer treatment course, slower onset of action and strong non-specificity, and the counterfeit products in the HGH market are widespread, and the source of the drug must be very reliable. 2.Proper treatment of injectable breast augmentation Injectable breast augmentation must be treated if there are local hard nodes, pain in the back of the chest, displacement and deformation of injectables, excessive psychological burden, affecting normal life and those who want to get pregnant. The treatment is best done by direct vision surgery and cannot be done by extraction again. MRI is required beforehand (ultrasound is only qualitative and of little significance) to clarify the location, shape and relationship of the injected material to the surrounding tissues. It is not necessary to extend the excision of all the involved tissues, otherwise it is not cost-effective and the result will only be the replacement of one deformity with another. If conditions allow, the implant can be replaced with a safer prosthetic material at the same time. However, this type of surgery is best performed in a large hospital by an experienced surgeon, and is best performed in the third trimester in pregnant women.
