Smiling makes us happy, while being unable to smile after Botox injections reduces the intensity of feelings. Researchers say that while fighting age wrinkles, Botox actually deprives a person from our ability to make facial expressions so the face becomes a mask.
A recent study by researchers at Barnard College in New York showed that the lack of facial expressivity can influence our emotional experience. A person with a limited ability to make facial expressions is also unable to feel deep because immobility of facial muscles weakens the feedback to the brain which influences the intensity of emotions.
