Any operation is risky. The main risk of injecting Botulinum Toxin and Hyaluronic Acid is that doctors don't know the anatomical site, the safe area and level of injection, especially the personnel of non-medical institutions such as beauty salons have not received professional training and don't know the injection amount. Moreover, the state manages botulinum toxin according to the requirements of toxic drugs. If illegal drugs are used, it will lead to very serious complications and even life-threatening. Therefore, when injection treatment is needed, we must choose a regular medical institution to ensure the regularity of drugs, the standardization of treatment, sterility and the accuracy of treatment dose.
