Introduction
1. A relatively common side effect is facial stiffness and an unnatural smile.
2. Excessive administration of botulinum toxin injections for facial slimming may lead to dysphagia (difficulty swallowing).
3. Asymmetry of the face or muscle weakness at the injection site.
4. Some individuals may experience localized swelling and warmth following botulinum toxin injection.
Almost everyone hopes to have a delicate, petite face—a facial shape widely admired and favored under today’s aesthetic standards. Consequently, “face-slimming injections,” a minimally invasive cosmetic procedure, have grown increasingly popular among individuals seeking aesthetic enhancement. While these injections can indeed help achieve a more refined facial contour, they are not without potential risks. So, what are the possible adverse effects of face-slimming injections? Below, we address this question in detail.
Potential Risks of Face-Slimming Injections
1. A relatively common side effect is facial stiffness and an unnatural smile.
2. Excessive injection may lead to difficulty swallowing.
3. Asymmetry between the two sides of the face or muscle weakness at the injection site.
4. Some individuals may experience localized swelling and warmth following injection.
5. Over-weakening of the masseter muscle or unintended diffusion of the injected toxin into adjacent muscles, resulting in corresponding symptoms.
6. A small number of patients report systemic reactions after botulinum toxin injection, such as fever, general malaise, or fatigue.
Additional Information: Important Precautions for Face-Slimming Injections
Face-slimming injections involve localized botulinum toxin administration into the masseter muscle to treat masseter hypertrophy. After the procedure, patients should rest quietly for 20–30 minutes before leaving the clinic and avoid strenuous physical activity. Facial massage and hot baths or showers should be avoided for two weeks post-injection. Aminoglycoside antibiotics (e.g., gentamicin) must also be avoided. Patients should sleep with their head elevated and avoid pressure on the injection site to prevent toxin diffusion; lying flat should be avoided for at least four hours post-treatment. For benign masseter hypertrophy, intermittent chewing of sugar-free gum—three times daily for 15 minutes each—is recommended within the first three days after injection. Repeat botulinum toxin injections should be spaced at least six to eight months apart. Should any adverse symptoms arise post-procedure, patients should promptly contact their physician or visit the clinic for evaluation.
The above outlines the potential risks associated with face-slimming injections. We hope this information proves helpful to you.
