The Brain Why Darwin Would Have Loved Botox

In June 2008 in the Journal of the American Academy of Dermatology, a team of cosmetic surgeons suggested this experiment is making all of us happier. People with Botox may be less vulnerable to the angry emotions of other people because they themselves can’t make angry or unhappy faces as easily. And because people with Botox can’t spread bad feelings to others via their expressions, people without Botox may be happier too. The surgeons grant that this is just speculation for now. Nevertheless, they declare that “we are left with the tantalizing possibility that cosmetic procedures may have beneficial effects that are more than skin deep.”

Maybe. But for all the Botox youthfulness plastic surgeons may want to think about, neuroscience raises a darker possibility. Making faces helps us understand how other people are feeling. By altering our faces we’re tampering with the ancient lines of communication between face and brain that may change our minds in ways we don’t yet understand.
