Yes, according to a study by researchers, a symmetrical face is indeed a turn on while a beauty spot, wonky nose or a lopsided grin are just a turnoff, The Daily Telegraph reported on Wednesday.

"Symmetry has been shown to be important in mate-choice in many. While there may be cultural variation in preferences for other traits, we show that symmetry in faces is attractive across two very different cultures," lead researcher Dr Anthony Little was quoted as saying.

In fact, the researchers came to the conclusion after conducting a study on over 100 people in Britain and the Hadza of Tanzania -- the last hunter gatherer culture -- and found that "symmetry transcends racial and national boundaries".

According to the findings published in Proceedings of the Royal Society, Biological Sciences journal, a lopsided face is less attractive to both Hadza and Britons, "so that the age-old idea that beauty is in the eye of the beholder is a romantic myth.

"This adds to mounting evidence that our appreciation of beauty has a deep-seated biological explanation – the attraction of a face gives a profound insight into whether our intended will efficiently pass our genes on to future generations".

"The Hadza live in small bands and survive by hunting and gathering and have very little exposure to Western standards of beauty having seen only a few White people.

However, the Hadza had stronger preferences for symmetry than those in the UK," another researcher Coren Apicella said.
