Introduction
The瘦脸针 (muscle-relaxing injection) usually works by causing the masseter muscle to atrophy, thereby achieving a slimming effect on the face. If the injection dose or placement is improper, it may lead to facial indentation. If the indentation is mild, as the botulinum toxin is gradually metabolized in the body over 3-6 months, the masseter muscle will slowly regain some strength and volume, and the indentation will also improve progressively. During this period, certain adjunctive measures may also accelerate the recovery process.

瘦脸针一般是通过麻痹面部咬肌,使肌肉缩小,从而达到瘦脸的效果。瘦脸针的一般参考价格为1500-4600元/次,一般1-3个月可见一定改善。瘦脸针凹陷通常能恢复,要注意前往正规医院就诊,在医生的指导下进行处理。

瘦脸针通常是使咬肌萎缩从而达到瘦脸效果,若注射剂量或位置不当可能导致面部凹陷。如果凹陷程度较轻,随着肉毒素在体内逐渐代谢,通常3-6个月,咬肌会慢慢恢复一定的力量和体积,凹陷也会随之逐渐改善。在此期间,通过一些辅助方法也可能加快恢复,比如适当咀嚼口香糖等锻炼咬肌。

如果凹陷较为严重,可能恢复时间会延长到6个月以上,部分人可能需要通过注射玻尿酸、自体脂肪填充等医美方法来修复凹陷。此外,个人的新陈代谢速度也会影响恢复时间,新陈代谢快的人恢复相对较快,若代谢较慢,可能恢复较慢。

建议做好日常护理工作,保持皮肤的清洁卫生。日常注意避免挤压、碰撞注射部位,以免影响恢复。
