Researchers found that Botox injections, which smooth out facial lines by partially freezing muscles, also have uplifting side effects that make patients smile.
Psychologists studied 25 people – 12 of whom 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.
The 'Basic Instinct' beauty Sharon Stone likes her reflection less since she turned 51, but still loves her "strong" nose. She said: "I have a really good nose. Our family has good noses - each different, but all strong and defining."
When it comes to beauty treatments, Sharon subscribes to the "less is more philosophy". She doesn't wear much makeup, never gets facials and sees her hairdresser as little as possible. But no matter how busy she is, she always makes time for regular massages, meditation and long baths.
