It has been suggested that botulinum toxin A (BTX-A) treatment for frown lines can also be used as a treatment for depression. A psychological mechanism for this effect is reviewed in which paralysis of the corrugator (frown) muscles leads to less facial feedback for negative emotions. Consequently, a negative affect is harder to maintain and so the person has a more positive mood.
In order to test this mechanism, the mood of patients who had received BTX-A treatment for glabelar frown lines was measured and compared with patients who had received other cosmetic treatments.
The BTX-A-treated patients showed significantly less negative mood.
The results support the facial feedback view that frowning can make one unhappier. Treatments that prevent frowning correlate with reduced negative mood.
有人提出，肉毒杆菌毒素A（BTX-A）治疗皱眉纹也可用于治疗抑郁症。本文回顾了这种效应的一种心理机制，即皱眉肌麻痹会减少负面情绪的面部反馈。因此，负面情绪更难维持，所以患者会有更积极的情绪。
为了验证这一机制，对接受BTX-A治疗眉间皱眉纹的患者的情绪进行了测量，并与接受其他美容治疗的患者进行了比较。
接受BTX-A治疗的患者负面情绪明显较少。
结果支持面部反馈观点，即皱眉会让人更不开心。防止皱眉的治疗与负面情绪的减少相关。
