Lip Attractiveness: A Cross-Cultural Analysis

Treating the Latin American Aesthetic Patient: A Review

The rich and diverse heritage of Latin American people contributes to a large variety of physical features, which translates to a patient population with a range of motivations for seeking cosmetic procedures and unique perspectives that influence their aesthetic preferences. As there is no one standard of beauty, it is important for physicians to understand the various factors that influence their patients' perceptions of beauty and desires to seek cosmetic treatment, especially because patient preference may differ from the physician perspective. Physicians in Latin America must consider the demographic, ethnic, and cultural factors that influence their patients to ensure culturally sensitive treatment approaches, natural-looking results, and patient satisfaction. This review includes a discussion of published literature, combined with the expert opinion of the authors, to provide a detailed description of the elements that impact aesthetic perceptions of patients living across the Latin American diaspora and highlights important gaps in research for future studies to address.

Lip Augmentation With Saypha LIPS Lidocaine: A Postmarket, Prospective, Open-Label, Randomized Clinical Study To Evaluate Its Efficacy and Short- and Long-term Safety

BACKGROUND

Versatility, biocompatibility, and reversibility make hyaluronic acid fillers the backbone of minimally invasive lip augmentation procedures.

OBJECTIVES

The aim of this study was to assess the effectiveness and short- and long-term safety of Saypha LIPS Lidocaine (Croma Pharma, Leobendorf, Austria) for lip augmentation to correct moderate to severe lip volume deficiency (grade 1-3 lip fullness score [LFS]).

METHODS

In this postmarket, prospective, open-label, multicenter, randomized clinical study, 114 patients were initially treated (with optional touch-up treatment at Week 3). Retrograde and bolus techniques were employed with defined needles or cannula. The primary effectiveness endpoint was the proportion of patients with lip volume improvement of LFS ≥ 1 grade vs baseline at Week 6 (ie, responders); with follow-up (FU) for secondary effectiveness at Months 6, 12, and 18. Evaluation scores included the LFS, Global Aesthetic Improvement Scale (investigator and patient), patient satisfaction questionnaire FACE-Q, and a numerical pain rating scale.

RESULTS

At Week 6, >90% of the patients were responders (lower-lip: 95% CI, 92.24-99.43, P = .0071; upper-lip: 95% CI, 90.95-99.00, P = .0234), with post hoc analyses showing the outcome was influenced by the initial volume deficiency and total volume injected, but not by touch-up treatment. At Month 6, 90% of the patients were responders; at Month 12, 70%; and at Month 18, >40% still had a visible effect. Adverse events were mostly procedural, mild, and temporary. Pain perception was significantly reduced 15 minutes after the procedure. Aesthetic improvement and patient satisfaction were rated as high at all time points.

CONCLUSIONS

Saypha LIPS Lidocaine for lip augmentation showed long-term aesthetic improvement and safety.

The perception of lip aesthetics in the context of facial proportions-An eye-tracking-based analysis

BACKGROUND

Minimally invasive lip volumizing and contouring soft tissue filler procedures are frequently requested by both female and male aesthetic patients. Guidance on how to achieve the most beautiful outcome is inconsistent.

OBJECTIVE

To investigate what the most beautiful proportions are in relation to vermillion thickness, the distance of the upper and lower lip in relation to nose and chin, and relation to the bigonial distance.

METHODS

This study included a total of n = 101 volunteers (52 females, 49 males, 100% Caucasian) who inspected frontal images of modified facial proportions and answered a related questionnaire showcasing the same images. Image presentation followed a randomized sequence both for the eye tracking and for the survey component of this study but was equal for all observers.

RESULTS

The most attractive vertical position of lips was the 1:2 ratio in which the distance between lips and chin is double the length as the distance between lips and nose. For the ratio between the width of the lips and the bigonial distance, it was the 1:2.5 ratio, whereas for the thickness of the upper lip vermilion in relation to the upper lip ergotrid it was the 1:3/1:2 (male/female) ratio and for the lower lip vermilion and lower lip ergotrid it was the 1:4 ratio for both genders.

CONCLUSION

The results of this eye tracking and survey-based investigation revealed that instead of one single universal ratio, multiple facial proportions exist that are perceived as most attractive/masculine/feminine. Regarding the perception of facial aesthetics, it appears there is a distinction between attractiveness and masculinity/femininity: the most attractive male/female face is not necessarily the most masculine or feminine.

Clinical Features and Biophysical Characteristics of Lips of South Asian Women

Introduction

The vermillion lip has unique physical properties and environmental exposures make them prone to dryness and chapping. While lips contribute to facial beauty, perioral aging is highly individual and dependent on ethnicity. Specifically with regard to South Asian population, there is no other literature identified on the biophysical characteristics of the vermillion lip.

Methods

In this work, characteristics of the vermillion skin in South Asians were examined through various clinical and biophysical characteristics of the lips such as dryness and roughness, fine lip lines, lip texture, hydration, and barrier function. Healthy South Asian females, from age 20-45 were recruited for this study and transepidermal water loss (TEWL), hydration, visual lip tolerance, and visual dryness were measured and graded by the dermatologist-investigator.

Results

Lip texture and fine lines significantly increased from the 20s to the 40s. Overall lip health significantly decreased with age. TEWL and dryness increased with age while hydration decreased with age, although not significantly so.

Discussion

This first-of-its kind study on South Asian females establishes that with age there is a decrease in overall lip health and an increase in signs of aging of the lips (fine lines, texture) from the 20s to 40s.

Aesthetic considerations when treating the Latin American patient: Thriving in diversity international roundtable series

BACKGROUND

The Hispanic/Latin American population is the fastest growing non-Caucasian group in the United States. Within this group, demand for aesthetic procedures is on the rise. High ethnic variability among these patients influences treatment approaches and patient priorities. Understanding these ethnic differences is central to providing optimal care.

AIMS

To discuss similarities and differences in anatomy and treatment preferences of Hispanic/Latin American patients both within the United States and internationally and explore how these differences may influence or inform aesthetic practices.

PATIENTS/METHODS

In support of clinicians who wish to serve a diverse patient population, a 6-part, international roundtable series focused on diversity in aesthetics was conducted from August 24, 2021 to May 16, 2022. In this roundtable, held in Medellin, Columbia, expert clinicians from across Latin America and the United States were invited to contribute and share best practices.

RESULTS

The results of the second roundtable in the series, the Latin American Patient, are described here. A special emphasis is placed on procedures that address the most commonly encountered concerns in these patients.

CONCLUSIONS

Hispanic and Latino patients represent a broad demographic with unique anatomical features, aesthetic preferences, and treatment priorities. Clinicians should consider these differences when treating this patient population.

Influence of Lip Appearances and Tooth Shade on Smile Attractiveness Perception

This study determined the effect of lip thickness, lipstick color, and tooth shade on the smile attractiveness perceptions of dentists, laypersons, dental students, and other faculty students. A set of 27 smile photographs was prepared with different lip thicknesses (Tk, thick; M, medium; and Tn, thin), lipstick shade (R, red; P, pink; and O, orange), and tooth shades (0M1, 0M3, and A1). A total of 212 Thai participants in four rater groups (dentists, laypersons, dental students, and other faculty students) rated smile attractiveness using a visual analog scale (VAS). Statistical analyses were performed using the Kruskal-Wallis test and pairwise analysis at a 0.05% level of significance. Tk or M lip thickness was associated with more smile attractiveness than Th lip thickness. The R lipstick is more attractive than the P and O lipsticks. The 0M1 tooth shade appeared to be the most attractive for laypersons and other faculty students, whereas tooth shades (0M1, 0M3, or A1) did not influence the smile attractiveness perception of dentists and dental students. The smile attractiveness perception was influenced by the lip appearance and tooth shade for each rater group, which are essential for an attractive smile design.

Lip Reshaping with LOVE Approach: A Prospective Analysis Based on Two Hyaluronic Acid Fillers

Aesthetic improvement of the lips with hyaluronic acid fillers is a popular procedure. A comprehensive, modular, and highly individualizable method has been developed: the Lip Omnicomprehensive Volume Enhancement (LOVE) approach. The present study assessed the safety and effectiveness of LOVE across different patient age groups.

Self-Acceptance and Interdependence Promote Longevity: Evidence From a 20-year Prospective Cohort Study

We explored psychosocial pathways to longevity, specifically, the association between psychological well-being and mortality in a 20-year prospective cohort study of 7626 participants. As hypothesized, high self-acceptance and interdependence were associated with decreased mortality risk, controlling for other psychological components (purpose, positive relations, growth, mastery) and potential confounders: personality, depression, self-rated health, smoking status, body mass index (BMI), illness, and demographics. Self-acceptance decreased mortality risk by 19% and added three years of life. Longevity expectation fully mediated the relationship between self-acceptance and mortality. Interdependence decreased mortality risk by 17% and added two years of life. Serenity towards death fully mediated the relationship between interdependence and mortality. This is the first known study to investigate self-acceptance, interdependence, and serenity toward death as promoters of longevity, and distilled the relative contributions of these factors, controlling for covariates-all of which were measured over multiple time points. Theoretically, this study suggests that components of well-being may make meaningful contributions to longevity, and practically recommend that self-acceptance and interdependence could be added to interventions to promote aging health.
