The perfect face is that of Bella Hadid . The model was officially declared ​ ​ ​ the most beautiful woman in the world. It is not a matter of taste, but of mathematical calculations, and with those it is no joke.

The famous London aesthetic surgeon Julian De Silva has thought of doing the (pleasant) task, taking advantage of the ancient Greek canons of beauty, summarized in the rule of the golden section. If this term, in English Golden Ratio, tells you something, maybe it's because it was used a few years ago to calculate the perfect body, which ​ then turned out to be Scarlett Johansson's - which, moreover, also wins the ​ title of beauty for the eyes.

The plastic surgeon spent months studying the faces of famous women measuring the proportions of eyes, eyebrows, nose, lips, jaw, face shape and chin, to establish that the face of Bella Hadid, with the percentage of 94,

35%, it borders on the perfect proportion in the relationship between forehead, eyes, chin, lips It is therefore the super model to win, thanks to

Mother Nature - and the geniuses, thinking that the sister is Gigi Hadid - ​ ​ ​ the title of most beautiful woman in the world.

Followed at close range Beyoncé , who, with his score of 92.44%, is the ​ ​ second most beautiful woman in the world. To close the podium is Amber

Heard, with a percentage of 91.85%.

Still on the subject of almost perfect proportions, Ariana Grande, Taylor ​ Swift and Kate Moss follow . Despite talking about very high ​ percentages, the perfect face in an absolute sense would result from a mix, putting together the shape of the face of Beyoncé (perfect at 99.6%), the eyes of Scarlett Johansson (perfect at 99.9%), the Amber Heard's nose

(99.7% perfect), Cara Delevingne's lips and eyebrows (98.5% and 94% respectively), Bella Hadid's chin (99.7%), Kate's forehead Moss (98.8%).
