Injections of Botox work by slightly freezing muscles to smooth out wrinkles. The "emotionless" face that can sometimes result is often the center of many jokes. But can this emotionless face, along with creating an unpleasant blank-faced effect, actually cause depression?

"Suppressing negative emotions is something we do every day to be polite," research leader Dr. Judith Grub told The Sun. "However, my research shows that paralyzing muscles that help you to express emotion leads to internalizing these feelings," she added. Of course, there's the flip side.
