The results of a study on the proportion of attractive lips have been published, drawing attention.

A joint research team at American University in Beirut, Lebanon, had a total of 200 participants evaluate the aesthetic appeal of lips after varying the proportion and volume of female face images generated by AI.

As a result, the ideal lip received the highest rating when the ratio of the upper and lower lips was between 0.618:1 and 1:1.




It was also evaluated as most attractive when the height of the upper lip was about 25% of the total width of the lip.

This is close to the 'golden ratio' considered the standard of beauty in ancient Greek art, and excessively inflated lips can be rather unfavorable.

The researchers analyzed "It is true that social media is influencing the standard of beauty, but research shows that traditional aesthetic standards are still valid" and "Some people's excessive lip cosmetic plastic surgery requests may be combined with individual psychological factors in addition to SNS influences."




The researchers also say, `Many people show pictures of Hollywood stars and want a look similar to them"Some filler operators are trying too hard, resulting in excessive procedures and side effects." he warned.

In the study, images with excessively inflated lips scored the lowest aesthetically, contrary to trends favored by some celebrities.

On the other hand, natural and balanced lips like Angelina Jolie, Anne Hathaway, and Scarlett Johansson were highly praised.




The researchers emphasized that "ideal lips make laughter stand out, a natural form in which volume and curve are harmonized.'

"Even if preferences vary according to nationality, race, and occupation, it does not change that the balance between the upper and lower lips is an important aesthetic criterion," he added. "The goal of the procedure is to emphasize natural beauty, not to over-expand it."

The findings were recently published in the international journal 『Plastic & Reconstructive Surgery - Global Open』.
