Revealing the Perfect Smile: How Philtrum Length Shapes Lip Beauty.
Article in Aesthetic plastic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLips significantly influence facial aesthetics, driving the growing demand for lip augmentation procedures, particularly the bullhorn lip lift. As aesthetic medicine becomes more diverse with globalization, understanding how ethnicity affects aesthetic perceptions of lips is increasingly important.
objectivesTo examine the philtrum length and lip proportions in the context of different ethnic backgrounds, recognizing the increasing globalization of beauty standards.
methodsFive frontal facial images of females from diverse ethnic groups-African, Asian, Caucasian, Latino, and Middle Eastern-were generated using Midjourney and were edited to simulate various degrees of philtrum shortening and corresponding changes in the upper vermillion height and maxillary incisor show. An online survey was then conducted to gather participant feedback on the aesthetic appeal of the lips in each image, using a 5-point Likert scale.
resultsA total of 570 respondents participated in the study. Overall, the most preferred lips were those with a 1 mm incisor show in African and Asian images, while lips with a 0.5 mm incisor show were favored in Caucasian and Latino images, and 0 mm in Middle Eastern images. The least favored lips were predominantly those with a 4 mm incisor show. Preferences across age and ethnic groups primarily favored the 0 mm, 0.5 mm, and 1 mm incisor shows.
conclusionsThis study provides valuable insights into the complex relationship between philtrum length and the perception of beauty. The findings emphasize the importance of achieving a balanced aesthetic that aligns with the patient's cultural background and personal preferences.
