Abstract
To compare the attractiveness of lips with different volumes after filling in the view of laypersons, dentists, and specialists. The sample comprised close-up frontal and lateral photographs of the lips of 16 women who underwent lip filling procedure with hyaluronic acid and was divided into 2 groups. Group 1: eight women with thinner lips at pretreatment. Group 2: eight female patients with thicker lips at pretreatment. Photographs from before and 10 days after lip filling were used to assess attractiveness randomly displayed in a Google Forms questionnaire and then sent via a messaging app to the evaluators. The evaluators' groups were general dentists, dentists with degrees in facial aesthetics, and laypersons. The attractiveness was evaluated with scores from 0 to 10 (0: least attractive and 10 the greatest). T-tests were used for the statistical comparisons. The group with thinner lips showed significantly improved attractiveness after filling. The group with thicker lips showed a worsening attractiveness after filling. The group with thicker lips had significantly higher attractiveness scores than those with thinner lips. There was no significant difference in the preference between men and women. The group of laypersons was more rigorous, giving significantly lower lip attractiveness scores. Thinner lips showed a significant improvement in attractiveness after filling. Thicker lips showed a worsening of the attractiveness score after filling. Before and after filling, thicker lips had significantly higher attractiveness scores than thinner lips.Clinical relevance: The amount of fillers applied to each patient must be individually evaluated.
