Uses of botox

PhysOrg reports:
Researchers studying the effects of Botox, a chemical used to smooth out facial wrinkles, have found the paralysis of facial muscles can reduce feedback to the brain and in turn reduce the intensity of emotional responses, especially to mildly positive stimuli.

Botox contains a protein (onabotulinumtoxinA) that temporarily paralyzes the facial muscles that create the creases we call wrinkles. This reduces wrinkles, but can also make the face lack expression and appear frozen. ...

The results, published in the journal Emotion indicated the Botox patients reported an “overall significant decrease in the strength of emotional experience” compared to the Restalyne group. The response to mildly positive clips was especially reduced after the injections. The group on Restylene did not experience the reduced emotional response, but did show an unexpected increase in response to negative clips.

The researchers said the results suggest feedback from facial expressions is not necessary for emotional experience, but may exert an influence in some circumstances. ...

Botox injections were the most common non-surgical cosmetic procedure used in the USA in 2009
Soon, shrinks will be prescribing botox for depression. The idea is if you are worried a lot, and you also look in the mirror a lot, and you don't look worried, then you will convince yourself that all is well. It makes as much sense as other psychiatric drugs.

Update: I had no idea that teenaged girls are getting botox:
“We do a lot of Botox, and there’s definitely a propensity for younger people doing it,” says Dr. Glenn Vallecillos, a Beverly Hills plastic surgeon. “I’d say 30 percent of my clients are 20 to 25 years old and probably 5 to 8 percent are under age 20. The trend, at least at our offices, is younger people.”

Statistics also suggest Botox use is trickling down even younger.

In 2009, the American Society for Aesthetic Plastic Surgery reported 12,110 Botox or Dysport (another wrinkle-relaxing shot) procedures performed on patients 18 and under (in 2008, the number was 8,194) while the American Society of Plastic Surgeons found 11,889 cosmetic Botox/Dysport procedures were performed on patients age 13 to 19 (an increase of 2 percent from 2008).
