Medical and physiological studies going back decades, have been investigating the link between using injectable toxins to neutralize movement in facial muscle and its connection to both the recognition and response to emotional responses. Knowing how connected the brain is to muscle reactions both decisive and reactive, autonomic and controlled, I myself have wondered at the long term effects from muscle freezing facial expressions. It turns out the brain needs this muscle stimuli to help respond to something that is happy, sad or angry. It also helps us read micro expressions in others and react with empathy. Freezing the muscles that help the face emote sadness has been successfully used to treat depression, because it lessens the severity that the clients “felt” their sadness. Now translate that to the treatment of laugh lines, and it can translate that it is possible you would feel less happiness with those muscles frozen because they are producing less stimuli to the brain. Of course you are still feeling happiness, sadness and anger when using injectable cosmetic neurotoxins. What is interesting is that you are feeling them LESS than before and having a harder time reading those emotions in OTHERS. The brain to muscle connection is fascinating. I hope you are encouraged to do a deep dive into this intriguing subject.
