Local adverse reactions may occur after injecting the face-slimming needle, mainly including excessive weakness of the masseter muscle and corresponding symptoms caused by the spread of the face-slimming needle to adjacent muscle tissue. However, there is no need to worry too much about these. The clinical manifestations are related to the injection site and the dose of the face-lift injection. Some individual beauty seekers find that they have fever, discomfort, fatigue and other symptoms after being injected with Botulinum Toxin from Huizhou Pengai Hospital. But it will disappear quickly within a certain period of time.
