There are many candidates who think that the injectable rhinoplasty method will be safer and without any risk, this is a wrong idea. Although the injection method is convenient and quick without surgery, and the results are obvious immediately after surgery, the risks are still not to be underestimated. However, the risks are still not to be underestimated, and the safety is generally affected by the following two factors. Types of injectable materials: Most of the injectable rhinoplasty materials nowadays are biological tissue materials, which are generally not harmful to the human body. The common injectable rhinoplasty materials on the market are hyaluronic acid, collagen and autologous fat. However, due to lax market supervision, fake products are widespread. If the choice is not careful, or the material itself has quality problems, there is still a possibility of serious consequences. Therefore, the choice of injectable materials is of utmost importance. Injection operation: The materials used for rhinoplasty are generally mucus-based, so if the injection method is not standardized, and the injection is too deep or too shallow, there is a possibility that the material will penetrate into the surrounding tissues, which may cause serious consequences, such as skin fistula, local ulceration, necrosis and so on. Severe cases may even lead to facial vascular embolism or blindness. Therefore, when choosing injectable rhinoplasty, beauty seekers must choose a regular plastic surgery hospital to ensure the quality of rhinoplasty materials and be operated by professional doctors to avoid accidents. Can I have a rhinoplasty by injection myself? The results of rhinoplasty injections are fast, no surgery is needed, and the effect can be obvious in a few minutes after the injection. Therefore, some beauty seekers will have the idea of injecting rhinoplasty themselves for various reasons such as economic benefits. And some shady businesses, in order to increase sales, will sell products with a video of injection operations. However, the risk of doing so is very high. Rhinoplasty injections require the selection of the right injection point and the amount to be used, because each person’s nasal structure has anatomical differences, the doctor must make adjustments while injecting. Since professional doctors have a deeper understanding of the basic structure of the skin and muscles, facial nerves, blood vessels, muscle direction, morphology and physiological functions, they can achieve the best injection effect according to their experience, and at the same time, they will have a good idea of the various complications that may arise from the injection and the corresponding disposal. Therefore, only doctors who have passed formal professional training and have rich experience in plastic surgery can be competent.
