New research suggests botulinum toxin type A (Botox, Dysport, Xeomin) has anti-depressive qualities along with its well-known cosmetic effects.
Researchers from the University of Texas Southwestern, Austin, found that botulinum treatments injected between the eyebrows had an anti-depressive effect even after the treatment wore off and wrinkles returned. This suggests that the improvement in mood isn’t related solely to the treatments’ cosmetic benefits.
The most significant finding is that the anti-depressant effects of the treatment lasted beyond the cosmetic effects. Even when patients’ frown lines went back to normal, their depression symptoms continued to get better.
What this means is that more study is warranted to see if this may be another tool in the treatment of depression but not a replacement for current therapy.
