Smiling Makes You Look Younger

Smiling is Mother Nature’s way of giving you a youthful appearance.

For some, the mere thought of smiling in front of a camera can be distressing and they make it a habit of not smiling. A study publishing in Psychology and Ageing showed that when people looked at photos of happy faces, they guessed the age of the person in the photo as younger than in photos of the same person not smiling.

“Although age estimates can often be based on multiple cues, there are many situations in which a picture of a person’s face is the only information that is immediately available,” researcher Manuel C. Voelkle of the Max Planck Institute for Human Development in Berlin, and colleagues write.

“In particular, with the rise of private- or business-related social networks like Facebook, flickr, LinkedIn, and many others, it has become common practice to share pictures, often without additional background information,” they write.

Researchers say pictures of happy faces may be misleading because smiling or laughing creates temporary wrinkles around the eyes and mouth. In a picture, it is harder to tell the difference between temporary wrinkles and real ones.

In addition, smiling has been shown to make people look more attractive, which may make them appear younger.

Guessing Age in Photos

In the study, 154 young, middle-aged, and older adults guessed the age of 171 faces of young, middle-aged, and older men and women with various expressions portrayed on a total of 2,052 photographs. Each face displayed either an angry, fearful, disgusted, happy, sad, and neutral expression.

The results showed facial expressions had a big effect on the accuracy of age estimates.

Compared with other facial expressions, the age of neutral faces was estimated most accurately.

Meanwhile, the age of happy or smiling faces was most likely to be underestimated by an average of about two years.


Want another reason to smile? Live Longer!

A university study (Abel & Kruger, 2010)¬†found that people with wide, happy smiles often live an extra 5 – 8 years longer compared to people who don’t! Whereas people who smiled with their mouth closed only gained around 3 extra years.
