Botox May Affect the Ability to Feel Emotions

Compared with the control group, the Botox participants "exhibited an overall significant decrease in the strength of emotional experience," the researchers wrote in a paper published in the June issue of the journal Emotion. In particular, the Botox group responded less strongly to mildly positive clips after they had the injections than before the Botox.

The findings tie into an idea suggested more than a century ago that feedback from facial expressions to the brain can influence the experience of emotions, the researchers said. The simple act of smiling, for example, can help make you feel happy, while frowning can bring down your mood.

"In a bigger picture sense, the work fits with common beliefs, such as 'fake it till you make it,'" Davis said.
