The aging perioral region -- Do we really know what is happening?

Facial morphology analysis of Caucasian Brazilian adult women using stereophotogrammetry

This cross-sectional observational study aimed to evaluate and compare facial metrics in women aged 20-65 years using a three-dimensional (3D) stereophotogrammetry system and to establish standardized values for facial metric variations in different age subgroups. This study included 84 Caucasian women divided into two groups based on their age: group 1 (G1) included women aged 20-40 years and group 2 (G2) included women aged 41-65 years. Twenty-one morphometric points on the face were identified, and the facial images were captured using a 3D stereophotogrammetry system, Twenty-three linear measures and 12 angular measures were evaluated, revealing statistically significant differences in 11 linear and 5 angular measures between the groups. In the G2 group, nasal and mouth width, lip philtrum height, Tragus-Nasion and Tragus-Pronasale lengths were increased, along with increased nasofrontal angle, decreased palpebral fissure inclination, and lip vermilion angles. However, palpebral fissure width and height, binocular width, and lip vermilion height were reduced. The aging process in women causes substantial changes in facial features, particularly in the middle and lower thirds of the face. Conversely, no major changes were observed in the upper third of the face. Our study findings provide potential insights for clinicians in developing facial rejuvenation procedures as well as for forensic purposes and surgical planning. The standardized facial metrics values in different age subgroups can guide clinicians in determining appropriate treatment plans for patients seeking facial rejuvenation.

Profiloplasty and facial contouring with injectables: A holistic, practical, and user-friendly approach

BACKGROUND

Expansion of the aesthetic treatment armamentarium with novel injectable products has greatly improved our ability to reshape and enhance the facial profile. However, full-face "profiloplasty" with injectables remain a nascent concept and is insufficiently considered in daily practice. While techniques have been widely published for treating the individual facial areas that constitute an attractive profile-including the forehead, nose, lips, jawline, and chin-the literature remains fragmented on more universal methods for profile improvement.

AIMS

To collate disparate knowledge on profile optimization with injectables, and define a holistic, practical, and user-friendly approach to profiloplasty and facial contouring.

METHODS

Consideration is given to key anatomical aspects and the changes that occur with age; patient assessment parameters for planning profiloplasty; and the technical specifications, product selection, and essential safety considerations for minimizing the risk of complications and optimizing the effectiveness of treatment.

RESULTS

Relevant case studies are presented.

CONCLUSIONS

Holistic approaches of this type are essential if we are to maximize the potential of full-face treatment with injectables-both now and in the future.

Comparative 3D Analysis of Lip Rejuvenation: Investigating Effects Before and After Soft-Tissue Filler Compared with Controls

BACKGROUND

The aim of this study was to evaluate changes in lip metrics before and after facial rejuvenation treatment with hyaluronic acid-based fillers and to compare them with those of a control group using stereophotogrammetry (3D).

METHODOLOGY

This study included 63 Caucasian women divided into Group C (<30 years, n=30) and Group H (>30 years, n=33), which was further divided into before (HT0) and after (HT1) lip augmentation with hyaluronic acid (HA). Eleven anthropometric landmarks were identified for linear, angular, and surface area measurements. Three photos were captured in Group C, while Group H had photos taken at T0 and T1. Statistical analysis was conducted using the Shapiro-Wilk test to evaluate normality, the Kruskal-Wallis test and one-way ANOVA. Tukey's post hoc and pairwise comparison tests were performed to analyze differences between variables (P value < 0.05).

RESULTS

There were significant differences between lip width (ChR-ChL) and philtrum width (CphR-CphL) (P<.001). The total heights of the upper (Ls-Li) and lower vermilion lips (Sto-Li) increased, and the heights of the upper (Sn-Ls) and lower (Li-Sl) cutaneous lips decreased. The angles related to the philtrum (ChR-CphR-Ls, P<.001; ChL-CphL-Ls, P<.001) and nasolabial angle (Prn-Sn-Ls) (P<.001) exhibited significant differences. The surface areas of the upper, lower, and total vermilion lip showed significant differences (P<.001). Tukey's test indicated no significant differences in surface area after lip augmentation between the HT1 and C groups.

CONCLUSION

Analysis of lip morphology after a filler procedure revealed a reversal of age-related changes, with increases in vermilion lip height and surface area comparable to those of younger individuals.

Can Vitamin D Levels Alter the Effectiveness of Short-Term Facelift Interventions?

Facelifting is increasingly popular among the population. It exceeded the limits of post-traumatic facia-reconstruction. Both the demand and the methods available are getting increasingly diverse. The minimally invasive technique revolutionized the facelift, although it took some time to completely comprehend the mechanics. The roles of vitamin D in numerous physiological processes in which it is involved have mostly been elucidated in the last decade. Our hypothesis is based on one of these roles, that is, vitamin D intervenes in changing the type of collagen by changing its location; therefore, collagen will have a supporting role for the subcutaneous tissue. A group of 156 patients with different facelifting methods was followed: 93 minimally invasive (NC), 49 classical surgery (C) and 14 with the combined technique (NC + C). The change in the subcutaneous tissue was monitored by an elastograph. The level of vitamin D was monitored in order to assess the immediate and long-term effects of vitamin D on the progression of subcutaneous fibrosis. It was proven that an optimal level of vitamin D has a beneficial effect in maintaining the volume of subcutaneous tissue in patients from the NC and NC + C groups, the best results being in the NC + C group. An increase in the subcutaneous volume was recorded, which leads to a decrease in elasticity (statistical significance p < 0.05) and the lowering of the subcutaneous tissue, and an increased amount of lowering corresponds to a lowering of vitamin D levels.

Age- and sex-related differences in 3D facial shape and muscle pressure in subjects with normal occlusion

BACKGROUND AND OBJECTIVE(S): (1) To derive descriptive statistics of three-dimensional (3D) facial shape, lip and cheek muscle pressure in subjects of European descent with normal dental occlusion. (2) To analyse the effect of age and sex on 3D-facial soft tissue morphology and muscle pressure in the same sample. (3) To assess the independent effect of muscle pressure on face shape.

METHOD

129 subjects with normal occlusion were cross-sectionally recruited and divided into: children (mixed dentition), adolescents and adults (permanent dentition, < and ≥18 years respectively). Muscle pressure was recorded using the Iowa Oral Performance Instrument. MeshLab, MeVisLab and Meshmonk tool box were used to clean, annotate landmarks and generate the 3D images. Two-way analysis of variance and post-hoc tests were used to analyse age and sex differences in face shape and muscle pressure. The effect of muscle pressure on face shape was analysed by Pearson correlation and Partial Least Square regression.

RESULTS

Significant facial differences were observed between adults and adolescents and adults and children in both sexes, showing flattening of cheeks and lips and protrusion of nose and chin. Significant cheek protrusion and retrusion of the vertical midface were found in adult women compared to men. Lip and cheek pressure increased with age, but their effect on face shape was not significant.

CONCLUSIONS

This study provides 3D age- and sex-specific facial models and muscle pressure of subjects without malocclusion. These can be used as a reference for clinicians focused on facial assessment in treatment planning and follow-up.

Non-ablative laser treatment improves lip volume, texture, and color

Lips undergo several changes with age, decreased volume, elasticity, turgor, and collagen content. Q-switched Nd:YAG laser are known to increase the production of procollagen and elastin and can promote the generation of collagen, which visibly improves facial imperfections. We aimed to determine the efficacy of a 1064 nm Q-switched Nd:YAG fractional laser on improving lip definition, color, and volume. 32 female patients were treated every 2-3 weeks for a total of 3-5 treatments. Improvement was measured in a follow-up visit a month after the final treatment (29.9 ± 1.4 days) by patients' self-satisfaction questionnaire and physicians blinded evaluations (Likert scale). Patients achieved meaningful aesthetic improvement in in lip color (94% of patients), volume (72%), texture (91%), and overall lip appearance (82%). Furthermore, 91% were satisfied with treatment results and 100% from the overall experience. There were no associated side effects, and the associated pain level (on a 0-10 scale) was rated as 0 in 84% of individuals and 16% as 1. Therefore, laser treatment using a 1064 nm Q-switched Nd:YAG fractional laser on lips is a safe, noninvasive treatment that increases the color and volume of lips, with results that are maintained for at least one month following treatments.

Lip Augmentation

Just as priceless procedure of art and science needs the visual frame to bring out the subtle proportion to your face and bring out the best frame for the smile. Lip augmentation procedures with hyaluronic acid dermal fillers have become increasingly popular worldwide because full lips are often considered beautiful and youthful. The objective of a lip augmentation procedure is to create smooth lips with adequate volume and a natural appearance and not to be over corrected. Various techniques for lip augmentation have been used and described.

Older adults' facial characteristics compared to young adults' in correlation with edentulism: a cross sectional study

Background

Facial ageing is a result of superficial wrinkling combined with changes to the underlying soft tissues and skeleton. The influence of tooth loss, as a geriatric characteristic, on facial appearance is still poorly explained. The aim was to evaluate the facial characteristics of older adults, correlate these characteristics with the dentition and make comparisons with young adults using a non-invasive 3D methodology.

Methods

90 participants older than 65 years, classified into 3 subgroups (edentulous, partially edentulous, toothed) and 30 young adults were evaluated. Their faces were scanned with an optical Artec 3D-scanner. Cephalometric analyses were made using the RapidForm computer program. An independent t-test and ANOVA were used for the comparisons. Pairwise, post-hoc tests were applied with respect to the significant differences (P < 0.05).

Results

The faces of older adults are wider and longer because of the longer middle facial height. Older adults also have a longer upper lip, a larger nose, a smaller nasolabial angle (due to the nasal ptosis), narrower upper- and lower-lip vermilions and larger facial and lower-facial-height angles, resulting in a flat facial profile.

The facial changes due to ageing are the most pronounced in the edentulous. In comparison with the toothed, they have a smaller facial height due to the smaller lower facial height, larger nasolabial angle, smaller mouth width, shorter upper lip and narrower lip vermilions. Their profile is flatter and their lips are more retruded.

Conclusions

The proportions of the whole face are changed in older adults and they are the most expressed when this is combined with tooth loss.

Rejuvenation of the ageing face and the role of orthodontics: Guidelines for management

The article reviews the ageing changes of the midfacial and maxillary bones, the mandible, the overlaying soft tissues and the smile, and presents clinical guidelines aiming to rejuvenate older faces by means of orthodontic therapy. With regard to the ageing changes, the maxillary skeleton appears to rotate clockwise inferior to the orbit and becomes retrusive, and as a general pattern the midface contracts and deteriorates with age. Resorption below the mental foramen, reduction in alveolar height, loss of bone at the chin region, and relative increase in size and shape are signs of an aged mandible. Epidermal thinning and decrease in collagen in combination with the effect of gravity and various external factors contribute to the ageing of the skin. Atrophy of the superficial and deep fat, changes in ligamentous tissues and changes in muscle structure, position and tone, all contribute to the stigmata of the aged face. In the article, two late adulthood orthodontic cases are discussed as examples, and general guidelines for orthodontic management of the older face aiming at reversing the 'shrinkage' of the tissues by restoring the facial shape and tightening the soft tissue mask are described. The possible mechanisms explaining the changes observed on the faces of the clinical cases are also discussed. A properly planned and executed orthodontic intervention reversing changes from the inside-out before embarking on cosmetic surgery might have a synergistic effect multiplying the benefits for adult patients.

Efficacy and safety of hyaluronic acid fillers for lip augmentation in a Chinese population

BACKGROUND

Hyaluronic acid (HA) is an effective dermal filler for facial rejuvenation. This study aimed to observe the clinical efficacy of HA injection for lip augmentation in Chinese patients.

METHODS

From May 2019 to April 2020, 70 patients with lip fullness scale (LPS) ≤3 underwent local HA injection using the "three-point" injection technique. All patients were followed up to observe the clinical efficacy, LPS, adverse events, and complications.

RESULTS

All 70 patients were followed up for 12 months. Statistically significant improvements were observed in the height of lips within 6-9 months post-treatment (p < 0.05). The LFS improved significantly at follow-up compared with baseline (p < 0.05). Local redness occurred in two patients, and serious swelling occurred in three patients. These adverse events were generally tolerated and disappeared gradually within 1 week. No other serious adverse events and complications were reported in the remaining patients.

CONCLUSIONS

Hyaluronic acid injection can be used for lip augmentation in the Chinese population. The "three-point" technique is simple, safe, and effective and does not cause serious complications.

Efficacy and Safety of a New Resilient Hyaluronic Acid Filler in the Correction of Moderate-to-Severe Dynamic Perioral Rhytides: A 52-Week Prospective, Multicenter, Controlled, Randomized, Evaluator-Blinded Study

BACKGROUND

The perioral region is highly mobile and subject to multifactorial changes during aging. Resilient Hyaluronic Acid Redensity (RHAR), an RHA filler, was developed with the aim of optimizing outcomes in dynamic facial areas.

OBJECTIVE

This randomized, blinded, multicenter clinical study aimed to demonstrate superiority of RHAR over no-treatment control for correction of moderate-to-severe dynamic perioral rhytides.

MATERIALS AND METHODS

Blinded live evaluator assessments of efficacy included improvement in perioral rhytides severity using a proprietary scale (Perioral Rhytids Severity Rating Scale [PR-SRS]) and the Global Aesthetic Improvement Scale. Subjects self-assessed their results with FACE-Q, a validated patient-reported outcome measure, and satisfaction scales. Safety was monitored throughout the study based on common treatment responses (CTRs) and adverse events (AEs).

RESULTS

The primary efficacy end point was achieved, with the treatment group showing statistically significant superiority over the control group at Week 8 (80.7% vs 7.8% responder rate by PR-SRS, p < .0001). Most patients (66%) were still responders at Week 52 (study completion). Most AEs were CTRs after perioral injection of a dermal filler, and none was a clinically significant treatment-related AE.

CONCLUSION

Resilient Hyaluronic Acid Redensity is effective and safe for the correction of dynamic perioral rhytides in all Fitzpatrick phototypes, with marked durability.

The Facial Aging Process From the "Inside Out"

The normal course of aging alters the harmonious, symmetrical, and balanced facial features found in youth, not only impacting physical attractiveness but also influencing self-esteem and causing miscommunication of affect based on facial miscues. With this evidence-based paper, the authors aim to provide a comprehensive overview of the latest research on the etiology and progression of facial aging by explaining the aging process from the “inside out,” that is, from the bony platform to the skin envelope. A general overview of the changes occurring within each of the main layers of the facial anatomy is presented, including facial skeleton remodeling, fat pad atrophy or repositioning, changes in muscle tone and thickness, and weakening and thinning of the skin. This is followed by an in-depth analysis of specific aging regions by facial thirds (upper, middle, and lower thirds). This review may help aesthetic physicians in the interpretation of the aging process and in prioritizing and rationalizing treatment decisions to establish harmonious facial balance in younger patients or to restore balance lost with age in older patients.

A minimalistic approach for effective lip augmentation-A case report

BACKGROUND

Lip augmentation using dermal fillers is a widely performed procedure, which gives immediate and gratifying results. However, the cost associated with it is a major concern and reservation for a lot of patients. An innovative minimalistic technique can be used to enhance the lips using minimal amount of filler to provide maximum results, especially in aging lips. Though a simple and effective method, this technique has not yet gained popularity worldwide.

AIM

To present a case demonstrating a new and innovative technique for lip augmentation as a part of lower face rejuvenation.

METHOD

A 55-year-old female patient underwent augmentation of lips using the described technique. Since she had a limited budget, treatment was planned to rejuvenate her face in just 1 ml of filler. Areas on the face which would give maximum impact with minimal amount of filler were treated. Treatment was done using Juvederm Ultra Plus XC (JUV_X+ ; 24 mg/ml) dermal filler.

RESULTS

Using this technique, we were able to demonstrate that a small quantity of filler when used suitably with an understanding of the areas of concern could provide an impact on the overall rejuvenation.

CONCLUSION

The described technique is an effective method of lip enhancement with minimal cost, especially in aging patients. Skillful application of a suitable injection technique is required to achieve a desired esthetic outcome.

A Randomized, Blinded, Prospective Clinical Study Comparing Small-Particle Versus Cohesive Polydensified Matrix Hyaluronic Acid Fillers for the Treatment of Perioral Rhytids

BACKGROUND

Perioral rhytids are a bothersome sign of aging for many patients. Although multiple treatments exist, choosing an optimal modality may be difficult considering that rhytids in this region are fine and the anatomy dynamic.

OBJECTIVES

The authors sought to compare the efficacy and safety as well as patient satisfaction of a small-particle hyaluronic acid filler with 0.3% lidocaine (SP-HAL, Restylane Silk) and cohesive polydensified matrix hyaluronic acid filler (CPM-HA, Belotero Balance) in reducing superficial perioral rhytids.

METHODS

The study was double-blinded, and 48 patients with moderate to severe superficial perioral rhytids were enrolled. Patients were randomized to receive either CPM-HA in the left perioral region and SPHAL in the right or vice versa. Rhytid severity was measured by patients utilizing a linear analog scale, and by investigators utilizing a validated 5-point scale, for 180 days following treatment.

RESULTS

Both SP-HAL and CPM-HA achieved a reduction in rhytid severity, and neither treatment group returned to baseline after 180 days. Investigator-reported scores for rhytid severity were significantly better for SP-HAL than CPM-HA and remained so at 180 days (P < .05). SP-HAL also proved significantly better for reducing rhytids according to patient scores, although this difference occurred between 120 and 180 days only. Adverse events included rash and mild acne for CPM-HA, and SP-HAL was associated with 1 postinflammatory nodule and 2 occurrences of Tyndall effect.

CONCLUSIONS

Although both SP-HAL and CPM-HA are effective at reducing perioral rhytid severity and have similar safety profiles, SP-HAL possesses a longer duration of effect.

Three-Dimensional Photogrammetric Study on Age-Related Facial Characteristics in Korean Females

Background

Understanding the age-related morphological changes of facial soft tissue is fundamental in achieving improved outcomes of rejuvenating procedures. Three-dimensional (3D) photogrammetry is a reliable and convenient anthropometric tool to assess facial soft tissue.

Objective

The aim of this study was to establish age-related facial soft tissue morphology in Korean adult females using non-invasive 3D photogrammetry.

Methods

One hundred and ninety-two female participants were divided into three groups based on age: the younger group (aged 20~39 years), middle group (40~59 years), and older group (60~79 years). Thirty-six landmarks were identified via 3D photogrammetric scanning (Morpheus 3D, Morpheus Co., Ltd., Seongnam, Korea). Forty-one facial dimensions were analyzed using the imaging software to find significance between the age groups.

Results

Smaller upper-facial volume (p=0.019) and shorter upper-facial height (p=0.034) were observed in the older group than in the younger group. In the mid-face, narrowed palpebral fissure (p<0.001) with elongated upper eyelid height (p<0.001) and widened nose (p<0.001) were observed in the older group compared with the younger group. Longer lower-facial height (p<0.001) with longer and wider philtrum (p<0.001, p=0.004, respectively), shorter lower vermilion height (p<0.001), wider mouth width (p<0.001), and smaller lower vermilion angle (p<0.001) were seen in the older group when compared with the younger group. Moreover, greater angles of nasofrontal, nasomental, and labiomental angle (p=0.015, p=0.015, p=0.080, respectively), and smaller nasofacial angle (p=0.034) were observed in the older group than in the younger group.

Conclusion

Our results provide clues of aging-related facial morphological characteristics in Korean female population.

Upper Lip Horizontal Line: Characteristics of a Dynamic Facial Line

Background: Upper lip appearance received major attention with the introduction of diverse treatment modalities, including lip augmentation, rhinoplasty surgery, and dental treatment designed to support the upper lip. Our objectives were to define the prevalence and characteristics of the upper lip horizontal line (ULHL), which is a dynamic line appearing during a smile, in relation to gender, malocclusions, aging, and facial morphology. Methods: First, the prevalence and gender distribution of ULHL was examined from standardized en-face imaging at full smile of 643 randomly selected patients. Second, cephalometric and dental cast model analyses were made for 97 consecutive patients divided into three age groups. Results: ULHL appears in 13.8% of the population examined, and prevailed significantly more in females (78%). The prevalence of ULHL was not related to age nor to malocclusion. Patients presenting ULHL showed shorter upper lip and deeper lip sulcus. The skeletal pattern showed longer mid-face, shorter lower facial height and greater prevalence of a gummy smile. Conclusions: Female patients with short upper lip, concavity of the upper lip, and gummy smile are more likely to exhibit ULHL. The ULHL is not age-related and can be identified in children and young adults. Therefore, it should be considered when selecting diverse treatment modalities involving the upper lip.

Stereophotogrammetry to reveal age-related changes of labial morphology among Chinese women aging from 20 to 60

Background

The lip is of important aesthetic value and highly subjected to aging. Collecting anthropometric baseline data and understanding age‐related changes of labial morphology can help with diagnosis of deformity, assessment of aging, and planning of cosmetic procedures. Many studies have focused on Caucasians, while there is a lack of anthropometric data on Chinese women.

Methods

A total of 169 women were enrolled in this cross‐sectional study and divided into four consecutive age groups. Linear distances, angles, and surface area data were obtained via stereophotogrammetry. Intergroup comparisons between different age groups were performed to find age‐related differences.

Results

Lip width significantly increased with age while philtrum width seemed to show no obvious change. Cutaneous upper and lower lip height increased, lengthening the lip in the vertical dimension. Decrease of upper vermilion height and changes in angles indicated that aging process shortened the upper vermilion and flattened the vermilion border. Surface area also showed age‐related changes. Intergroup comparison showed no statistical significance in most variables between 20s and 30s or 30s and 40s, while age‐related changes in some variables were significant between 40s and 50s.

Conclusion

This study provided anthropometric data of labial morphology across a wide age range. Aging process affected a variety of labial anthropometric variables. Age‐related changes accelerated after 40 among Chinese women.

Smile dimensions in adult African American and Caucasian females and males

OBJECTIVES

To test smile dimension variations in adult African American and Caucasian females and males.

SETTING AND SAMPLE POPULATION

The University of Alabama at Birmingham School of Dentistry and Hospital. Three hundred and ninety-four participants were recruited; African American females and males distributed over five age groups: 20-30, 30-40, 40-50, 50-60 and older than 60.

MATERIAL & METHODS

Three-dimensional surface imaging was used to acquire two images of each participant, one at rest and one upon smile. Landmarks were plotted on the lips and linear distances measured to assess the length of the upper and lower lips, mouth width at rest and upon smile, gingival and dental display upon smile.

RESULTS

Linear dimensions are larger in males than in females, and in African Americans than in Caucasians, except for the length of the upper lip that does not differ between male African American and Caucasian males, in any given age group. Gingival display and dental display decrease with age in all groups.

CONCLUSION

Norms should reflect race, age and sex in order to optimize treatment goals.

Age-related changes in lip morphological and physiological characteristics in Korean women

OBJECTIVE

Age-related changes in lip morphological and physiological characteristics are key indices for estimating age based on facial features, as reported in many studies. Yet, a majority of studies have focused on Caucasian individuals, with few studies characterizing these changes in Asian female populations. Therefore, the aim of this study was to investigate lip morphological and physiological characteristics in a cohort of Korean women.

METHODS

A total of 114 volunteers participated in the study. Linear distances (length of philtrum, length of lip, width of lip, and lengths of lower and upper oral commissures), angle of the upper lip, 3D lip heights, and wrinkles were calculated and averaged for each age-group. We also measured lip color, hydration, trans-epidermal water loss (TEWL), and blood flow. Statistical analyses were performed using SPSS version 20.0 (significance level P < 0.05).

RESULTS

Length of the philtrum and lip width significantly increased with age while upper and lower lip lengths and length of the lower oral commissure significantly decreased with age. The angle of the upper lip tended to decrease with age, but this finding was no significance. Three-dimensional height of the upper lip, wrinkles, and TEWL also decreased with age while hydration increased with age. Finally, redness of the upper and lower lips as well as blood flow significantly decreased with age.

CONCLUSION

Lips tended to shorten in length and widen with age, resulting in a thinner and longer appearance. With regard to physiological parameters, there were important age-related changes in hydration and lip color.

Gromwell (Lithospermum erythrorhizon) root extract protects against glycation and related inflammatory and oxidative stress while offering UV absorption capability

Glycation and advanced glycation end products (AGE) damage skin which is compounded by AGE-induced oxidative stress and inflammation. Lip and facial skin could be susceptible to glycation damage as they are chronically stressed. As Gromwell (Lithospermum erythrorhizon) root (GR) has an extensive traditional medicine history that includes providing multiple skin benefits, our objective was to determine whether GR extract and its base naphthoquinone, shikonin, might protect skin by inhibiting glycation, increasing oxidative defenses, suppressing inflammatory responses and offering ultraviolet (UV) absorptive potential in lip and facial cosmetic matrices. We show GR extract and shikonin dose-dependently inhibited glycation and enhanced oxidative defenses through nuclear factor erythroid 2-related factor 2 (Nrf2)/antioxidant response element activation. Inflammatory targets, nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB) and tumor necrosis factor alpha, were suppressed by GR extract and shikonin. Glyoxalase 1 (GLO1) and glutathione synthesis genes were significantly upregulated by GR extract and shikonin. GR extract boosted higher wavelength UV absorption in select cosmetic matrices. Rationale for the use of GR extract and shikonin are supported by our research. By inhibiting glycation, modulating oxidative stress, suppressing inflammation and UV-absorptive properties, GR extract and shikonin potentially offer multiple skin benefits.

High-Resolution Magnetic Resonance Imaging of Aging Upper Face Fat Compartments

BACKGROUND

Age-related changes in fat compartments have yet to be fully characterized. Uncertainty remains in terms of volume gains/losses or shape fluctuations over time. The authors' aim was to determine the evolution of subcutaneous fat in the aging upper face, focusing on shifts in volume and dimension.

METHODS

Over the course of 4.5 years, 100 faces of living female Caucasian patients were prospectively studied using high-resolution magnetic resonance imaging. Subjects were stratified by age as follows: group 1, 18 to 30 years; group 2, 30 to 60 years; and group 3, older than 60 years. Superficial temporal and central forehead compartments were delimited, analyzing respective volumes and dimensions by group.

RESULTS

In 85 patients studied, superficial temporal fat (mean volume, 5.14 cm) increased 35.48 percent in total volume between youth and old age (p = 0.046). Overall height and magnitude of the lower one-third also increased with aging. Central forehead fat (mean volume, 2.56 cm), studied in 83 patients, showed a 209.75 percent volume gain in group 2 (versus group 1) and a 17.59 percent volume loss in group 3 (versus group 2) (p = 0.001).

CONCLUSION

Subcutaneous facial fat fluctuates with aging, increasing in the upper face and promoting ptosis through basal compartmental expansion.

Características orofaciais de idosos funcionalmente independentes

RESUMO Objetivo conhecer as características orofaciais de idosos funcionalmente independentes e analisar a associação com a idade, gênero, nível socioeconômico e estado dentário. Método estudo observacional, transversal de caráter analítico com amostra não probabilística. Foi aplicado o instrumento validado “Protocolo de Avaliação Miofuncional Orofacial com Escalas para Idoso” em sujeitos funcionalmente independentes com idade igual ou acima de 60 anos, em boas condições de saúde segundo avaliação geriátrica padronizada, intitulada Protocolo de Avaliação Multidimensional do Idoso. Resultados os idosos apresentaram padrões de normalidade acima de 60% nos parâmetros de aspecto e mobilidade das estruturas. As alterações significantes foram: sulco nasolabial acentuado; bochechas flácidas ou arqueadas; vedamento labial com tensão ou ausência de vedamento e comissuras labiais deprimidas. As alterações de mobilidade foram pequenas, entre 20,6% e 33,8%, com maior prevalência na elevação da língua e lateralização do ar em bochechas infladas e da mandíbula. Não houve relação destes achados perante a progressão da idade e as classes socioeconômicas. As mulheres apresentaram maior chance de exibirem aspecto normal dos lábios e alguma alteração da mobilidade. O número de dentes associou-se com o volume e a configuração dos lábios e a mobilidade da mandíbula. Além disso, o uso de prótese dentária associou-se significativamente com o aspecto do sulco nasolabial e a tensão/configuração das bochechas. Conclusão este trabalho sugere que o sistema oromiofacial encontra-se dentro dos padrões de normalidade na maioria dos idosos funcionalmente independentes. O que ampara a atuação multiprofissional na prevenção, promoção e tratamento da saúde oromiofuncional dos idosos.

Age-Related Changes of the Orolabial Region in Caucasian Women: An Anthropometric Analysis

PURPOSE

Anthropometric data can provide valuable support for the attending physician in planning surgical and nonsurgical esthetic procedures with regard to a patient's age. The purpose of the present study was to identify age-related orolabial changes in younger and older Caucasian women.

MATERIALS AND METHODS

In the present cross-sectional study, anthropometric landmarks were identified using indirect anthropometry (2-dimensional photometry) in younger (≤35 yr) and older (≥50 yr) Caucasian women to analyze age-related parameters and proportions of the orolabial region, especially of the lower and upper lip vermilion areas. The Mann-Whitney U test was applied to compare the results between the younger and older populations.

RESULTS

The study population consisted of 45 women. The cohort was divided into a younger population (24 participants; mean age, 27.4 yr) and an older population (21 participants; mean age, 58 yr) to evaluate age-related differences. Increases of upper lip height, cutaneous height of the upper lip, and cutaneous height of the lower lip were observed in older women. In contrast, the vermilion height of the lower lip decreased significantly with increasing age.

CONCLUSION

These results show changes of the orolabial region occur in Caucasian women with increasing age. The statistically relevant decrease of the vermilion height of the lower lip should be given particular attention for (age-appropriate) diagnostic, esthetic, and prosthetic treatment planning.

[Esthetic dermatology for the elderly]

Esthetic dermatology discovers older age. Methods and techniques which are useful in younger people need modifications to meet the special needs of the elderly. These aspects are discussed with a focus on the aging face. Esthetic dermatology is most successful when using principles of regenerative medicine.
