Moreover, the injection will be accompanied by facial stiffness, unnatural smile, bilateral asymmetry or muscle weakness at the injection site. The occurrence of these side effects is related to the doctor's experience, and the dose of injection is related to the injection site. Some unqualified "beauticians" in life beauty salons are not familiar with anatomy, the injection site is inaccurate, or the concentration and dosage used are too large, which will cause drooping eyelids, drooping eyebrows and local swelling. After all, the injection itself is risky, and it is far from being healthy and safe to eat a small V-shaped face-lifting, so I want to have an injection and face-lifting check.
