“…Knowledge of the proportions in the upper lip-lower lip-chin area has a major impact on the perception of facial aesthetics [9,10,13,30]. It is possible to enlarge, refine, shorten and reshape lips with surgical techniques or with nonsurgical procedures like injectable soft tissue fillers such as bovine collagen or hyaluronic acid [8,24]. Dermal fillers are commonly used for aesthetic lip augmentation procedures which target to increase lip fullness, define lips and restore volume loss that may occur with aging and facial paralysis [2,8,21,24].…”

“…It is possible to enlarge, refine, shorten and reshape lips with surgical techniques or with nonsurgical procedures like injectable soft tissue fillers such as bovine collagen or hyaluronic acid [8,24]. Dermal fillers are commonly used for aesthetic lip augmentation procedures which target to increase lip fullness, define lips and restore volume loss that may occur with aging and facial paralysis [2,8,21,24]. Fillers and implants that have been widely utilized in clinical practice contain a series of applications including autologous implants (fat transfer), collagens (bovine, human), biosynthetic implants (polymethylmethacrylate microspheres in a carrier gel, expanded tetrafluoroethylene) and crosslinked hyaluronic acid gels, such as small gel particle hyaluronic acid (Fig.…”

“…They are one of the most attractive images of the face, achieving an aesthetic youthful and beautiful appearance [4,5]. The appearance including the shape, size, fullness and symmetry are important aspects of attractiveness [6][7][8]. The definition of Bperfect^or Bideal^lips changes, depending on factors such as age, ethnicity, culture, fashion and current trends [9][10][11][12][13].…”

“…Since the introduction of modern dermal fillers, lip augmentation has become one of the most commonly requested aesthetic procedures [8,24]. In addition to augmentation, this is achieved by using fillers to correct agerelated losses such as vertical rhytides, effacement of the lip margins and thinning of the lips [6,8,25,26].…”

“…In addition to augmentation, this is achieved by using fillers to correct agerelated losses such as vertical rhytides, effacement of the lip margins and thinning of the lips [6,8,25,26]. It is the central unit of the upper lip, which consists of the dimple, with two columns of the tubercle, and the white roll between the two high edges of Cupid's bow [4][5][6][7] (Fig.…”

Background Lip augmentation and changing contour lines have become more popular ways of improving the appearance. However, validated measures of lip fullness for quantification of outcomes are needed; ethnic background and personal goals can optimise outcomes while tailoring lip enhancement treatment to each individual's anatomy. The aim of this study is to analyse the morphological features of the lip in detail and to clarify the objective parameters in related with the subjective ones regarding the lip augmentation and lip reconstruction. Methods Standard photographs of the lips of 200 young Anatolian adults were calculated with linear and angular components. The features of the lower third of the face were analysed with the software program. Linear analyses (heights of the upper lip, the upper vermilion, the lower lip height, the lower vermillion and the chin height) and angular analyses (the upper lip, the lower lip, the apex and Cupid's bow angles) were measured as reference points. The lip shape was classified into five groups: thin, very thin, medium, full and very full. Results The lower third of the face was divided into three segments (Sn-Sto, Sm-Me and Sto-Sm), and the largest portion of the lower face was occupied by the chin and the smallest by the lower lip height in both genders. The upper vermilion height was 8.07 ± 1.8 mm in males and 7.08 ± 1.5 mm in females. The lower vermilion height was 10.1 ± 2.4 mm in males and 9.7 ± 1.9 mm in females. The upper lip angle was calculated as 30.3 ± 9.6°in males and 24.2 ± 6.2°mm in females. The lower lip angle was calculated as 38.3 ± 9.7°in males and 36.5 ± 6.4°in females. Meanwhile, the angular measurements of Cupid's bow (i.e., the apex and the central angle of Cupid's bow) were smaller in men than in women. When the lip was analyzed, the medium and full types in upper and lower lips accounted for substantial fractions in men, whereas medium and thin types were predominant also in women. Conclusions With the help of certain software, this research has made possible to define the best cosmetical redesign solution of lip construction and augmentation with a natural appearance for the patient. Level of Evidence: Level III, diagnostic study.

IMPORTANCE Aesthetic proportions of the lips and their effect on facial attractiveness are poorly defined. Established guidelines would aid practitioners in achieving optimal aesthetic outcomes during cosmetic augmentation.OBJECTIVE To assess the most attractive lip dimensions of white women based on attractiveness ranking of surface area, ratio of upper to lower lip, and dimensions of the lip surface area relative to the lower third of the face. DESIGN, SETTING, AND PARTICIPANTSIn phase 1 of this study, synthetic morph frontal digital images of the faces of 20 white women ages 18 to 25 years old were used to generate 5 varied lip surface areas for each face. These 100 faces were cardinally ranked by attractiveness through our developed conventional and internet-based focus groups by 150 participants. A summed ranking score of each face was plotted to quantify the most attractive surface area. In phase 2 of the study, 4 variants for each face were created with 15 of the most attractive images manipulating upper to lower lip ratios while maintaining the most attractive surface area from phase 1. A total of 60 faces were created, and each ratio was ranked by attractiveness by 428 participants (internet-based focus groups). In phase 3, the surface area from the most attractive faces was used to determine the total lip surface area relative to the lower facial third.

An Index for Quantitative Assessment of Lip Augmentation

Abstract: The Lip Index allows for the practical evaluation of the clinical effects and duration of dermal filler injectables or implants. Quantitative assessments of results over time are easy to calculate, without the need for complex measurements or sophisticated analyses.
