London, Apr 1 (ANI): By stopping the face from frowning, Botox jabs, which smooth out facial lines by partially freezing muscles, make patients feel happier, a new study suggests.
The treatment has been used by many celebrities including Queen of Pop.
Now, after studying 25 people, psychologists have found that Botox anti-wrinkle treatment can help beat the blues.
In the volunteer group, 12 had Botox injections to the forehead, while the rest had fillers, peals or cosmetic treatments.
All the participants completed a mood questionnaire at least two weeks later, reports The Telegraph.
Patients who received Botox treatment were found to be significantly less depressed, anxious and irritable than those who did not.
Study leader Dr Michael Lewis, from the University of Cardiff, said: "Both groups had some form of cosmetic treatment, and there was no difference in how effective they thought their treatment had been.
"So this result is most likely due to the effects of Botox specifically."
Presenting the research at the British Psychological Society's annual meeting in Brighton, Dr Lewis added: "This research may help the development of a new treatment for depressive illnesses.
"Unlike other treatments for depression, which have significant negative side effects, the main side effect of a Botox-based treatment would be a younger-looking face.
Dr Lewis explained that by blocking frowning, Botox prevents expressions of negative emotion, resulting in a happier mood.
"But as the cosmetic effect of Botox is temporary, so will be the emotional effect. As the effect of the Botox wears off, one's mood is likely to return to normal levels," Dr Lewis said. (ANI)
