Eight is the average number of years British people would like to shave off their looks. The optimum age that Brits step up their beauty regime is 32 and the top three triggers for this are the appearance of fine lines and wrinkles, having more disposable income and a photograph of themselves looking old. The interesting facts are revealed in a newly published survey, which saw 10,000 women and men questioned across the UK, France, Germany, Italy and Spain. The Beneath the Skin of Beauty report, funded by Allergan and published in July 2011, reveals how they felt about beauty and the ageing process. Those surveyed were aged between 20 and 60. The survey results highlight a number of similarities across gender and cultural divides, but also some marked differences - reaffirming a few age old preconceptions and also revealing a few surprises. Highlights of the UK survey included the fact that 48% of British women said stress has the most detrimental effect on looks and a third blamed bad eating habits or dieting. Over half of those British men and women who have had injectable treatments for facial lines and wrinkles would now choose to have them earlier.
