Botox is a popular cosmetic procedure to reduce facial wrinkles. Botox is injected into various muscles, for instance in the face, and it paralyzes the muscles thereby causing the wrinkles to “relax”. It’s been known for a while that one of the side effects of Botox treatments are that people can’t fully express emotions (for example, they can’t move the muscles that would show they were angry, or even happy). New research shows another interesting side effect – people who have Botox injections can’t feel emotions either.
