Are there side effects to facial slimming injections? As modern women increasingly desire a smaller face, attention has turned to these treatments. The conventional method involves botulinum toxin injections. This toxin, produced by Clostridium botulinum bacteria, primarily causes muscle paralysis and atrophy. In large doses, it can lead to total muscle paralysis and death.When injected locally, it can paralyze and atrophy the muscles in the treated area, reducing volume and improving appearance. Botox has a nerve-blocking effect and is widely used in neurology, ophthalmology, plastic surgery, and cosmetic surgery.
For patients with enlarged masseter muscles, resulting in a wide facial appearance, small doses of botulinum toxin can be injected. However, precise injection placement and appropriate dosage are crucial. Typically, the toxin dissipates within about six months, and muscle regrowth occurs, making recurrence common. The average duration of effect ranges from 2 to 8 months, with 6 months being typical.
To maintain facial slimming effects, injections are generally required every six months. If administered every three months for 3-5 consecutive sessions, muscle atrophy becomes less likely to reverse. Potential side effects include reduced chewing strength, inability to chew hard foods, skin laxity over the treated muscles, unnatural facial expressions, difficulty smiling, or a stiff smile.
Before undergoing facial slimming injections, assess potential allergies. This treatment is most suitable for individuals with well-developed masseter muscles and minimal subcutaneous fat. Those with excessive fat deposits may experience hollowed cheeks without overall facial slimming. Necessary pre-treatment physical examinations are essential to prevent adverse effects.
