Turn that frown upside-down? Not if you're keen on looking younger, you shouldn't. 
 
 A new study shows that smiling can make you appear to be two years older than if you wear a poker face. And if you reacted to that finding with a look of surprise -- well, that expression might just have dropped years from your visage. 
 
 "We associate smiling with positive values and youth," said study co-author Melvyn Goodale, director of the Brain and Mind Institute at Western University. "Think of all the skin-care and toothpaste companies that sell the same idea every day." 
 
 But this study -- in which researchers flashed images of people with smiling, neutral and surprised expressions -- showed the opposite: participants perceived the surprised faces as the youngest and smiling faces the oldest. 
 
 "The striking thing was that when we asked participants afterwards about their perceptions, they erroneously recalled that they had identified smiling faces as the youngest ones," Goodale said. "They were completely blind to the fact they had 'aged' the happy-looking faces. Their perceptions and their beliefs were polar opposites." 
 
 Goodale said the aging effect of a smile stems from people's inability to ignore the wrinkles that form around the eyes during smiling. A look of surprise, on the other hand, smooths any wrinkles. 
 
 "It may seem counter-intuitive, but the study shows that people can sincerely believe one thing and then behave in a completely different way," Goodale said. ||||| These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to.

– Poker-faced celebs like Victoria Beckham may have figured this out already: smiling makes you look older. A new study out of Canada claims that contrary to the popular belief that a happy grin is a sign of "positive values and youth," researchers found that flashing those pearly whites can add a year or two onto your apparent age, the New York Daily News reports. The study by Brain and Mind Institute at the University of Western Ontario involved showing participants images of people with various expressions: smiling, neutral, and surprised. When asked to rate each expression youngest to oldest, the faces showing surprise were deemed the youngest; a wide-eyed look of wonder can shave years off your apparent age. But when we smile, crinkly wrinkles appear around the eyes that participants took as a sign of age. A surprised expression, on the other hand, pulls the skin back and had the effect of erasing signs of age. Interestingly, when asked later about their perceptions, participants in the study published in the journal Psychonomic Bulletin and Review incorrectly recalled that they had tagged the smiling faces as the youngest. “They were completely blind to the fact they had ‘aged’ the happy-looking faces," co-author Melvyn Goodale says in a news release. "Their perceptions and their beliefs were polar opposites.” So what's the takeaway? To Goodale the study reveals that while "it may seem counterintuitive … people can sincerely believe one thing and then behave in a completely different way.” (Simone Biles had this to say when told she should smile.)
