Beauty is certainly in the eye of the beholder. What you might think is beautiful and what I consider beautiful can be completely different. However, using a formula called the Golden Ratio of Beauty Phi, researchers can use science to determine what is considered ultimate beauty. The supermodel pictured above (Bella Hadid) has just been labeled the Most Beautiful Woman in the World by British cosmetic surgeon Dr. Julian De Silva, as reported by the Daily Mail.

The Golden Ratio of Beauty uses the ancient Greek formula of ratios between the eyes, ears, nose, chin shape, forehead size and other variables (like your ear should be the same length as your nose). Leonardo Da Vinci used the formula when he drew the Vitruvian Man. Renaissance artists used the Golden Ratio formula when painting their famous chapel portraits.

So yeah... according to science, here are the top five most beautiful women in the world:
