Halth Issue: FROZEN FACE: Lack of facial expressions...

Not just wrinkles, Botes jab can kill emotions too London: Botox may help you look young, but it can affect the development of emotions curtailing your happiness, a new study has claimed.        The research into Botox used to fight facial wrinkles found tht those who are unable to smile are less likely to be happy. Botox is made of an extremely toxic protein called Botulinum toxin that temporarily paralyses the muscles that cause creases.        But, researchers at Barnard College in New York found that lack of facial expressions may influence emotional experiences as well. They found that being unable to smile at the time of happiness feeds back to the brain reducing the intensity of feeling, the Telegraph reported.         "With Botox , a person can respond otherwise normally to an emotional event, such as a  sad movie scene, but will have less movement in the facial muscles that have been injected, and therefore less feedback to the brain about such facial expressivity," said lead researcher Joshua Davis.          For their study, Davis and his colleague Ann Senghas led a team of researchers who showed people emotionally charged videos bothy before and after they were injected with either Botox. or restylane - a substance injected into lips or facial wrinkles that fills out sagging skein.       Restylane was used as a control because it simply adds filler but doesn't limit the movement of muscles. Compared with the control group, the Botox participants "exhibited an overall significant decrease in the strength of emotional experience," the researchers said. The simple act of smiling can help make you feel happy, while frowning can bring down your mood, they added.
