More Evidence Botox Works for Depression

A single injection of cosmetic botulinum toxin (BTX), which is typically used to improve the appearance of facial wrinkles, may be an effective treatment for depression.

In one of the first studies to suggest this, investigators at the Hannover Medical School in Germany found that treating the facial muscles involved in emotion with botulinum alleviates depressive symptoms.

“Our emotions are expressed by facial muscles, which in turn send feedback signals to the brain to reinforce those emotions. Treating facial muscles with botulinum toxin interrupts this cycle,” study investigator Prof. Tillmann Kruger said at a press conference at the American Psychiatric Association’s 2014 Annual Meeting.
