The number of teenagers injecting Botox has risen 800% over the last several years. It now seems that the ability of Botox to freeze facial expression may cause stunted emotional growth in teenagers. This is based on something called “facial feedback hypothesis.” Our emotional experiences are regulated in part by our facial expressions. They fear that administration of Botox to “young people” may lessen/stunt their ability to express their emotions. I personally do NOT have young teenagers requesting Botox and if I did I probably would respectfully decline.
