Enhancing Aesthetic Harmony: Comprehensive Anthropometric Lip Measurements in Youthful and Attractive Indonesian Adults for Precision Cosmetic Procedures

Lips are an important part of our perception of beauty, youthfulness and attractiveness. Aesthetic lips, as with the rest of the face, differs according to age, ethnicity and sex. The aim of this study was to evaluate the anthropometric measurements of the lips of young and attractive Indonesian adults. Photographs of faces were taken at an anterior neutral position for 100 participants; 47 men and 53 women volunteered to participate in this study. Seven landmarks were used in this study: stomion (st), sublabiale (sl), subnasale (sn), labiale superius (ls), labiale inferius (li), crista philtre (cp) and chelion (ch). Using these landmarks, lower lip height, upper lip height, philtrum length, upper vermillion height, lower vermillion height, cutaneous lower lip height, philtrum width and mouth width were measured. The results were analysed using independent t-test and Mann-Whitney test. Significant differences in lip size were observed between men and women in all the measurements st-sl (lower lip height), sn-st (upper lip height), sn-ls (philtrum length), li-sl (cutaneous lower lip height), sn-ls/ls-st (philtrum length and upper vermillion height) and ls-li/ch-ch (cutaneous lower lip height and mouth width) with a significance of p=0.003, p=0.007, p
