  • Eye-tracking devices find viewers spend more time looking at lips considered less attractive.
  • Researchers find that lip proportion of 1:1.6 (upper lip to lower lip) was rated as most attractive.
  • “Visual attention […] is not reflective of the beauty in the image assessed; rather the opposite,” says study. 


A study shows that people often find that natural-looking lips are the most attractive in the present time, there is a trend of lip injections for fuller lips.

Eye-tracking devices have revealed that viewers actually spend more time staring at lips that are perceived as less attractive.

To conduct the study, researchers edited a set of images of women’s lips and asked participants  with or without medical or cosmetic training – to evaluate them.

“Visual attention, based on the results of this study, does not reflect the beauty of the assessed image; on the contrary,” says Sebastian Cotofana, MD, PhD, of the Mayo Clinic, Rochester, Minn and colleagues wrote in

After evaluation, researchers found that a 1:1.6 lip ratio (upper and lower lip) was considered the most attractive – a 1:1.6 ratio is known for The name “golden ratio” for beautiful lips. By comparison, an image showing a fuller lower lip (1:2) was found to be less attractive, with an average rating of 2.16 out of 5,444
However, in the eye tracking analysis , participants spent less time staring at the “natural” Lips they found most attractive. In contrast, they looked more at the digitally altered lips.

Dr. Cotofana says this is not surprising, dispelling the assumption that people spend more time watching something they find appealing.

“Visual stimuli that are consistent with socially influenced, inner beauty standards require less effort to perceive,” says Dr. Cotofana.

“In contrast, visual stimuli that did not meet the internal standard of beauty required more processing time, as evidenced by involuntary eye movements recorded by eye tracking.”
