The main component of瘦脸针 (facial slimming injections) is botulinum toxin type A. Possible side effects of administering瘦脸针 on the face include local reactions, muscle weakness, unnatural facial expressions, skin laxity, and muscle atrophy.
1. Local reactions: The injection site may experience mild redness, swelling, pain, bruising, or induration, which typically resolve naturally within several hours to days.
2. Muscle weakness: Because botulinum toxin works by blocking nerve impulse transmission at neuromuscular junctions, causing temporary muscle relaxation, muscles near the treatment area may experience temporary weakness.
3. Unnatural facial expressions: If the injection dosage or placement is inaccurate, it may affect the normal function of other facial muscles, leading to unnatural facial expressions, such as facial stiffness or a mask-like appearance. This condition may persist for a period after injection but generally improves gradually as the drug is metabolized and muscle function recovers.
4. Skin laxity: Long-term injections of瘦脸针 may lead to atrophy of the masseter muscle, thereby affecting its support of the skin. If the skin's elasticity is inherently poor, laxity may occur. Therefore, the patient's skin condition should be evaluated before injection, and potential risks should be explained.
5. Muscle atrophy: Prolonged or excessively frequent injections of high-dose botulinum toxin may cause permanent muscle atrophy in the treated area, affecting facial structure and function.
When considering the use of瘦脸针, individual health conditions should be fully evaluated, choices should be made cautiously, and good communication should be maintained with a qualified physician.
