When it comes to attractiveness, evenness of skin tone and a natural "glow" are most important, according to a new study from the UK.
Researchers photographed the faces of 170 women and applied their skin to an idealised computer model. Then 430 volunteers were asked to score them for attractiveness, the only variable being skin tone, the UK's Sunday Times reported.
Faces with a radiant, even tone were more likely to be considered attractive.
"Skin tone, especially in women, says a great deal about reproductive potential," said Dr Bernhard Fink, an expert in evolutionary psychology at the University of Göttingen in Germany.
Here are the celebrities who work the 'glow' the best.
