Facial signs

面部体征
  • 文章类型: Randomized Controlled Trial
    背景:在到达地球的所有紫外线(UV)辐射中,UVA1射线具有更高的穿透和产生临床有害后果的潜力。虽然高达370纳米的紫外线辐射被当前的防晒霜很好地阻挡,对于370和400nm之间的UVA1波长,保持光保护间隙。
    目的:这项研究旨在评估在户外夏季条件下,使用添加到参考SPF50防晒霜中的甲氧基丙基氨基环己烯叉乙氧基乙基氰基乙酸(MCE)过滤器对UVA1防护的色素沉着和皮肤老化迹象的影响,与没有MCE过滤器的相同防晒霜相比。
    方法:这项前瞻性随机个体间比较研究在巴西和中国的113名女性中进行。受试者的面部和两个前臂在8周内每天两次暴露于一小时的户外阳光照射。暴露前,将含有3%MCE的SPF50防晒霜涂在一个半面和一个前臂上,将不含MCE的相同参考产品涂在另一个半面和前臂上。主要研究终点是皮肤颜色变化(色度)。其他终点包括专家小组对色素沉着和面部皮肤老化进行分级,和面部皮肤光泽和均匀性的幼稚小组评估。
    结果:8周后,两个前臂的皮肤都较深,但是使用SPF50/MCE防晒霜,阳光诱导的色素沉着增加较小。专家小组评估显示,在用SPF50/MCE产品保护的区域中,色素沉着的严重程度评分没有变化,面部皮肤老化的严重程度评分降低;在单独用SPF50保护的区域中,严重程度评分增加(色素沉着)或不变(皮肤老化)。皮肤光泽和均匀性的初始小组评价显示SPF50/MCE产品的统计学显著的优越性。
    结论:总体而言,这项研究表明,与相同的SPF50防晒霜相比,SPF50/MCE防晒霜的保护作用显着减少了色素沉着和衰老迹象。
    BACKGROUND: Of all ultraviolet (UV) radiations reaching the earth, UVA1 rays have a higher potential of penetrating and producing clinically harmful consequences. While UV radiations up to 370 nm are well-blocked by current sunscreens, a photoprotection gap remains for the UVA1 wavelengths between 370 and 400 nm.
    OBJECTIVE: This study was to assess under outdoor summer conditions the impact on pigmentation and skin ageing signs of a protection against UVA1 using methoxypropylamino cyclohexenylidene ethoxyethylcyanoacetate (MCE) filter added to a reference SPF50 sunscreen, in comparison with the same sunscreen without the MCE filter.
    METHODS: This prospective randomized comparative intra-individual study was conducted in 113 women in Brazil and China. Subjects had their face and two forearms exposed twice-daily to a 1-h outdoor sunlight exposure over 8 weeks. Before exposure, the SPF50 sunscreen containing 3% MCE was applied on one half-face and one forearm and the same reference product without MCE on the other half-face and forearm. Primary study endpoint was skin colour changes (chromametry). Other endpoints included expert panel grading of pigmentation and facial skin ageing, and naïve panel assessment of facial skin radiance and homogeneity.
    RESULTS: After 8 weeks, the skin was darker on both forearms but the increase in sun-induced pigmentation was smaller with the SPF50/MCE sunscreen. Expert panel evaluations showed no change in severity scores for pigmentation and a decreased severity scores for facial skin ageing in areas protected with the SPF50/MCE product: severity scores in areas protected with the SPF50 alone were either increased (pigmentation) or unchanged (skin ageing). Naïve panel evaluations of skin radiance and homogeneity showed statistically significant superiority of the SPF50/MCE product.
    CONCLUSIONS: Overall, this study demonstrates that a protection with the SPF50/MCE sunscreen significantly reduces pigmentation and ageing signs compared to the same SPF50 sunscreen.

    目的:评估自动检测系统准确分级的能力,从智能手机\'自拍图片,南非妇女15种面部体征的严重程度及其与年龄和日晒习惯有关的变化。
    方法:基于自拍图像进行了两步法。起初,评估比勒陀利亚地区(25.74°S,28.22°E),由基于人工智能(AI)的自动分级系统测量的15个面部体征的年龄变化,该系统先前已由专家/皮肤科医生验证。第二,因为这些南非小组成员是根据他们通常的阳光照射行为招募的,也就是说,非阳光恐惧症(NSP,N=151)和防晒(SP,N=155),并通过他们定期和早期使用光防护产品,表征面部照片损伤。
    结果:(1)自动评分显示出随年龄的显着变化,十年来,20年和30年后的下垂和皱纹/质地(p<0.05),分别。随着年龄的增长,色素沉着簇得分没有显着变化,而脸颊皮肤毛孔在30年代和50年代出现两个平台时呈低幅度扩大。(2)60年后,在NSP与SP女性中观察到皱纹/纹理和下垂的严重程度显着增加(p<0.05)。50年后观察到眼睛轮廓色素沉着增加的趋势(p=0.06)。
    结论:这项工作说明了衰老和阳光照射对南非女性面部体征的具体影响,与以前在欧洲或东亚进行的实验相比。结果显着证实了避免阳光的重要性以及避免长期皮肤损伤的光保护措施。在包容性流行病学研究中,旨在调查在非常不同的背景下的大型人类小组,基于人工智能的系统提供了一个快速的,在面部体征的检测和量化及其与年龄的依赖性的负担得起的和保密的方法,环境,和生活方式。
    OBJECTIVE: To evaluate the capacity of the automatic detection system to accurately grade, from smartphones\' selfie pictures, the severity of fifteen facial signs in South African women and their changes related to age and sun-exposure habits.
    METHODS: A two-steps approach was conducted based on self-taken selfie images. At first, to assess on 306 South African women (20-69 years) enrolled in Pretoria area (25.74°S, 28.22°E), age changes on fifteen facial signs measured by an artificial intelligence (AI)-based automatic grading system previously validated by experts/dermatologists. Second, as these South African panelists were recruited according to their usual behavior toward sun-exposure, that is, nonsun-phobic (NSP, N = 151) and sun-phobic (SP, N = 155) and through their regular and early use of a photo-protective product, to characterize the facial photo-damages.
    RESULTS: (1) The automatic scores showed significant changes with age, by decade, of sagging and wrinkles/texture (p < 0.05) after 20 and 30 years, respectively. Pigmentation cluster scores presented no significant changes with age whereas cheek skin pores enlarged at a low extent with two plateaus at thirties and fifties. (2) After 60 years, a significantly increased severity of wrinkles/texture and sagging was observed in NSP versus SP women (p < 0.05). A trend of an increased pigmentation of the eye contour (p = 0.06) was observed after 50 years.
    CONCLUSIONS: This work illustrates specific impacts of aging and sun-exposures on facial signs of South African women, when compared to previous experiments conducted in Europe or East Asia. Results significantly confirm the importance of sun-avoidance coupled with photo-protective measures to avoid long-term skin damages. In inclusive epidemiological studies that aim at investigating large human panels in very different contexts, the AI-based system offers a fast, affordable and confidential approach in the detection and quantification of facial signs and their dependency with ages, environments, and lifestyles.

    目的:评估面部光泽或辉光对年龄感知(PA)的影响,并评估哪些面部体征对PA的影响最大。
    方法:六个不同种族/国家的1058名不同年龄的女性(18-80岁)的面孔(中国,Japan,韩国,印度,南非,和巴西)在标准条件下拍照。这些允许专注于20种不同的面部体征,这些体征由专家进一步分级,使用专用于面部老化的参考Atlases。在这六个国家中,招募了100名当地妇女作为天真的小组,以在当地研究妇女的每张全脸照片(盲编码)上表达他们对发光和年龄的看法。
    结果:在所有研究对象中,辉光/辐射度降低明显与感知年龄增加有关,尤其是中国人,日本人,南非妇女。关于面部体征,皮肤纹理(各种皱纹),下垂/下垂,除南非妇女外,几乎所有妇女都有色素沉着迹象和脸颊皮肤毛孔在Glow和PA的感知中占主导地位。在中国和日本女性中,色素沉着的迹象是非常高的。
    结论:尽管有一些集体协议,本研究显示了六个种族/国家妇女的一些特殊性。PA,抗衰老策略的核心指标,几乎所有研究过的女性都有面部发光。面部皮肤越迟钝,人们认为它越老。
    OBJECTIVE: To evaluate the impact of Facial radiance or Glow on the perception of age (PA) and to assess which facial signs most influence PA.
    METHODS: The faces of 1058 differently aged women (18-80 years) of six different ethnicities/countries (China, Japan, Korea, India, South Africa, and Brazil) were photographed under standard conditions. These allowed to focus on 20 different facial signs that were further graded by experts, using referential Atlases dedicated to facial aging. In each of the six countries, 100 local women were recruited as naïve panels to express their perceptions on Glow and Age on each full-face photograph (blind coded) of the local studied woman.
    RESULTS: A decreased Glow/Radiance appears clearly associated with an increased perceived age in all studied subjects, especially among Chinese, Japanese, and South African women. With regard facial signs, Skin texture (Wrinkles of all kinds), Ptosis/Sagging, and Pigmentation signs prevail in almost all women at the exception of South African women where Pigmentation signs and Cheek skin pores largely predominate in the perception of both Glow and PA. Pigmentation signs are of a very high weight among Chinese and Japanese women.
    CONCLUSIONS: Despite some collective agreements, the present study shows some specificities within the women of the six ethnicities/countries. PA, a core index of antiaging strategies, goes along with facial Glow in almost all studied women. The duller the facial skin, the older it is perceived.

    (1)背景:严重急性呼吸道综合征冠状病毒-2(SARS-CoV-2)在武汉出现,中国,2019年末。针对SARS-CoV-2的有效和安全疫苗的开发非常快。据报道,基于临床试验的BNT162b2和mRNA-1273疫苗的口面不良反应列表很少见。这项研究的目的是使用一项基于调查的研究来调查COVID-19疫苗接种的面部和口腔表现。(2)方法:问卷采用谷歌表格编制,匿名发给波兰共有700名受试者(医务人员),意大利,和其他欧盟国家。(3)结果:223人回答了问卷,主要接种BNT162b2。只有3.1%和5.4%出现口腔和面部症状,分别。一般疾病的存在和年龄对第二次给药后口腔症状发生的概率有显著影响。面部症状与一般疾病有关;自身免疫性病变和年龄,在第一和第二剂量时,分别。性别,吸烟和定期药物摄入对缺勤日的概率有显著影响。性别,年龄,吸烟对第二剂量后症状的持续时间有显著影响。(4)结论:根据本次初步调查的结果,未观察到COVID-19疫苗给药与面部和口腔表现之间的显著相关性。
    (1) Background: Severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2) emerged in Wuhan, China, in late 2019. The development of effective and safe vaccines against SARS-CoV-2 has been extremely fast. The list of orofacial adverse effects of BNT162b2 and mRNA-1273 vaccines based on the clinical trials are reported to be rare. The aim of this study was to investigate the facial and oral manifestations of COVID-19 vaccination using a survey-based study. (2) Methods: The questionnaire was developed using Google Forms and sent anonymously to a total of 700 subjects (medical personnel) in Poland, Italy, and other EU countries. (3) Results: 223 people answered the questionnaire, mainly vaccinated with BNT162b2. Only 3.1% and 5.4% experienced oral and facial symptoms, respectively. General diseases presence and age have significant influence on the probability of oral symptoms occurrence after the second dose. Facial symptoms are correlated with general disease; autoimmune pathologies and age, at first and second dose, respectively. Gender, smoking and regular medication intake have significant influence on the probability of taking an absence day. Gender, age, and smoking have a significant influence on the duration of symptoms after second dose. (4) Conclusions: Based on the results of this preliminary survey, there is no observed significant correlation between vaccine administration for COVID-19 and facial and oral manifestations.

    OBJECTIVE: To determine the respective weights of certain facial signs on the assessment of the perceived age and a tired-look on Korean men of different ages.
    METHODS: Photographs were taken of the faces of 101 Korean men (20-80 years) under standardized conditions. These photographs allowed to define 16 signs, which were then graded by 15 experts/dermatologists, using standardized scales provided by a referential Skin Aging Atlas. These signs were dispatched into 5 clusters, namely Wrinkles/Texture, Ptosis/Sagging, Cheek pores, Pigmentation, and Vascular signs. A naïve panel of 200 Korean individuals (100 women, 100 men), of similar age range, were asked, when viewing full-face photographs, to (a) attribute on a 0-10 scale their perception of a tired-look and (b) estimate the age of the subject.
    RESULTS: The severity of all clusters increased with age, although at different rates. The Wrinkles/Texture or Ptosis/Sagging showed a rather regular progression, whereas Vascular presented the weakest changes. Although perceived and real ages were found highly correlated, almost 85% of the subjects were judged older by 1-15 years. The signs/clusters were found significantly correlated with perceived age, highly for Wrinkles/Texture and Ptosis/Sagging, moderate for Pigmentation, and low for Vascular and Cheek pores. The weights in perceived ages of Wrinkles/Texture and Ptosis/Sagging represent 81% and Pigmentation at 19%. Facial tired-look of Korean men was found significantly correlated with perceived age. Although Vascular and Cheek pores were found not impacting, Wrinkles/Texture, Ptosis/Sagging, and Pigmentation presented a clear influence.
    CONCLUSIONS: Within facial clusters, Wrinkles/Texture, Ptosis/Sagging, and Pigmentation are major factors in the assessment of perceived age in Korean men. The perception of an increased tired-look is significantly associated with increased perceived age.

    OBJECTIVE: To evaluate the capacity of the automatic detection system to accurately grade, from smartphones\' selfie pictures, the severity of ten facial signs in Japanese women and their changes due to age and sun exposures.
    METHODS: A three-step approach was conducted, based on self-taken selfie images. At first, to check on 310 Japanese women (18-69 years) enrolled in the northerner Hokkaido area (latitude 43.2°N), how, on ten facial signs, the A.I-based automatic grading system may correlate with dermatological assessments, taken as reference. Second, to assess and compare age changes in 310 Japanese and 112 Korean women. Third, as these Japanese panelists were recruited according to their usual behavior toward sun exposure, that is, non-sun-phobic (NSP, N = 114) and sun-phobic (SP, N = 196), and through their regular and early use of a photo-protective product, to characterize the facial photo-damages.
    RESULTS: (a) On the ten facial signs, detected automatically, nine were found significantly (P < .0001) highly correlated with the evaluations made by three Japanese dermatologists (Wrinkles: r = .75; Sagging: r = .80; Pigmentation: r = .75). (b) The automatic scores showed significant changes with age, by decade, of Wrinkles/Texture, Pigmentation, and Ptosis/Sagging (P < .05). (c) After 45 years, a significantly increased severity of Wrinkles/Texture and Pigmentation was observed in NSP vs. SP women (P < .05). A trend of an increased Ptosis/Sagging (P = .09) was observed.
    CONCLUSIONS: This work illustrates, for the first time through investigations conducted at home, some impacts of aging and sun exposures on facial signs of Japanese women. Results significantly confirm the importance of sun avoidance coupled with photo-protective measures. In epidemiological studies, the AI-based system offers a fast, affordable, and confidential approach in detection and quantification of facial signs and their dependence with ages, environments and lifestyles.

    OBJECTIVE: To determine the respective weights of certain facial signs on the assessment of perceived age and plumpness on Korean women of different ages.
    METHODS: Photographs were taken of the faces of 112 Korean women of different ages (18-80 years) under standardized conditions. These photographs allowed to focus and define 19 facial signs, which were then graded by 15 experts and dermatologists, using standardized scales provided by a reference Skin Aging Atlas. The facial signs were dispatched into 5 clusters, namely Wrinkles/Texture, Ptosis/Sagging, Pigmentation disorders, Vascular disorders, and Cheek skin pores. A naïve panel, composed of 92 Korean women, of similar age range were asked, when viewing full-face photographs, to: (a) attribute on a 0-10 scale their perception of the skin plumpness (ie supple/hydrated/nourished) and (b) estimate the age of the subject.
    RESULTS: With the exception of Vascular disorders, the severity of all 4 clusters increased with age, although at different rates. The Wrinkles/Texture or Ptosis/Sagging showed a rather regular progression. Although perceived ages and real ages were found highly correlated, half of the subjects were judged older by 2-12 years. The facial signs/clusters were significantly correlated with perceived age, with the exceptions of vascular disorders, size of pigmentary spots and cheek skin pores. The weights in perceived ages of Wrinkles/Texture and Ptosis/Sagging represent 37% each and Pigmentation disorders at 26%. Skin plumpness was logically found significantly anti-correlated with perceived age. If, surprisingly, Vascular disorders were found not impacting the plumpness aspect, Cheek skin pores presented a clear influence.
    CONCLUSIONS: Within facial clinical clusters, Wrinkles/Texture, Ptosis/Sagging, and Pigmentation disorders are major factors in the assessment of perceived age in Korean women. The perception of a decreased skin plumpness is significantly associated with increased perceived age.

    OBJECTIVE: To evaluate the capacity of the automatic detection system to accurately grade, from smartphones\' selfie pictures, the severity of seven new facial signs added to the nine previously integrated.
    METHODS: A two-step approach was conducted: first, to check on 112 Korean women, how the AI-based automatic grading system may correlate with dermatological assessments, taken as reference; second, to confirm on 1140 women of three ancestries (African, Asian, and Caucasian) the relevance of the newly input facial signs.
    RESULTS: The sixteen specific Asian facial signs, detected automatically, were found significantly (P < .0001) highly correlated with the clinical evaluations made by two Korean dermatologists (wrinkles: r = .90; sagging: r = .75-.95; vascular: r = .85; pores: r = .60; pigmentation: r = .50-.80). When applied at a larger scale on women of different ethnicities, new signs were found of good accuracy and reproducibility, albeit depending on ethnicity. Due to contrast with the innate skin complexion, the facial signs dealing with skin pigmentation were found of a much higher relevance among Asian women than African or Caucasian women. The automatic gradings were even found of a slightly higher accuracy than the clinical gradings.
    CONCLUSIONS: The previously used automatic grading system is now completed by adding new facial signs apt at being detected. The continuous development is now integrating some limitations with regard to the constitutive skin complexion of the self-pictured subjects. Presenting reproducible assessments, highly correlated with medical grading, this system could change tremendously clinical researches, like in epidemiological studies, where it offers an easy, fast, affordable, and confidential approach in the objective quantification of facial signs.

    BACKGROUND: New gratification assessments, after skincare routines or makeup products, could benefit from innovative methods that could predict the culturally based perceptions of age.
    OBJECTIVE: To determine the facial signs that most influence the perception of age in women of five different ethnic ancestries, assessed by the same ethnical naïve panel.
    METHODS: The faces of 1351 women, differently aged (18-80 years), from five countries (China, France, India, Japan, and South Africa) were photographed under the same standardized conditions in the five countries. Fourteen to 24 facial signs (grouped under five clusters, ie, Wrinkles/Texture, Ptosis/Sagging, Pigmentation disorders, Vascular disorders, and Cheeks skin pores) were focused, and their respective severities were graded using referential Skin Aging Atlases by the same panel of 15 experts and dermatologists. Five naïve panels, all comprising 100 local women, allowed to collect the perceived age, assessed from blind-coded full-face photographs.
    RESULTS: Although perceived ages and real ages were found highly correlated, their differences vary according to ethnicities, particularly among a large part of Indian and South African women, judged older by about 5 and 7 years, respectively. Results show that the clusters of Wrinkles/Texture and Ptosis/Sagging are predominant factors taken into account in almost all ethnicities, albeit at various extents, reaching almost 100% in French women. Pigmentation disorders appear important secondary factors in Japanese, South African, and Indian women. Vascular disorders, of a difficult grading in darker skin tones, were found of some impact in Japanese and Chinese women. Cheek skin pores were of minor or nil weight in the attribution of age, at the exception of South African women. Regarding facial areas which drive aging perception, it seems the upper-half face has prevalence for Chinese and Japanese women whereas the lower-half face has major importance for South African women.
    CONCLUSIONS: Facial traits are differently perceived as signs of aging according to un-separable ethnic ancestries and cultural factors.

    OBJECTIVE: To determine the respective weights of certain facial signs on the assessment of perceived age, tired-look and healthy glow on Chinese men of different ages.
    METHODS: Photographs were taken of the faces of 420 Chinese men of different ages, under standardized conditions. These photographs allowed to focus and define 15 facial signs, which were then graded by 15 experts and dermatologists, using standardized scales provided by a reference Skin Aging Atlas. The facial signs were dispatched into 5 clusters, namely wrinkles/texture, ptosis/sagging, pigmentation disorders, vascular disorders and cheek skin pores. A naïve panel, composed of 80 Chinese women, of similar age range were asked, when viewing full-face photographs, to: (i) attribute on a 0-10 scale their perception of both the tired-look and healthy glow aspects and (ii) estimate the age of the subject.
    RESULTS: With the exception of vascular disorders, the severity of all 4 clusters increased with age, although at different rates. The ptosis/sagging or pigmentation disorders showed a rather regular progression. Although perceived ages and real ages were found to be closely correlated, the vast majority of subjects were judged older by 2-10 years. The changes in facial signs (and their related clusters) were significantly correlated with perceived age, with the exceptions of skin spot density and cheek skin pores. Although the aspects of tired-look and healthy glow were logically found to be anti-correlated, tired-look was more statistically associated with perceived age for the five clusters. Signs of eye contour appear to be closely correlated with the perception of a tired-look.
    CONCLUSIONS: Within facial clinical clusters, wrinkles/texture and ptosis/sagging are major factors in the assessment of perceived age in Chinese men. Tired-look appears to be strongly associated with perceived age.
    UNASSIGNED: De déterminer, pour des hommes chinois d’âges différents, les poids respectifs de certains signes faciaux entrant dans l’estimation de la perception des visages pour l’âge, l’air fatigué ou l’éclat. MATÉRIEL ET MÉTHODES: Les visages de 420 hommes chinois d’âges différents ont été photographiés dans des conditions standardisées. Ces clichés ont permis à 15 experts et dermatologistes d’évaluer 15 signes cliniques selon des échelles éditées dans les références Atlas Cliniques du Vieillissement. Ces signes faciaux sont regroupés dans 5 groupes (rides/texture, ptose/relâchement, désordres pigmentaires, désordres vasculaires, pores de la joue). Un panel de 80 consommatrices chinoises, d’un âge comparable, a été recruté pour donner leurs perceptions sur chaque visage complet photographié: d’abord en attribuant sur une échelle de 0 à 10 un score pour leurs perceptions de l’air fatigué et de l’aspect éclatant de santé, puis en estimant l’âge apparent du volontaire. RÉSULTATS: A l’exception des Désordres vasculaires, la sévérité des 4 groupes cliniques s’accroit avec l’âge selon des cinétiques différentes, parmi lesquelles la ptose/relâchement ou les désordres pigmentaires montrent la progression la plus constante et linéaire. Malgré une très importante et significative corrélation entre âge apparent et âge réel, une majorité des volontaires ont été jugés plus vieux que leurs âges réels, entre 2 et 10 ans. Les variations des signes faciaux (ou des groupes cliniques associés) ont été montrés significativement corrélées à l’âge apparent, à l’exception de la densité des taches pigmentaires et des pores de la joue. Bien que l’air fatigué et l’éclat sont logiquement observés comme anti-corrélés, c’est l’air fatigué qui se trouve le plus relié à l’âge apparent sur les 5 groupes cliniques. Les signes du contour des yeux apparaissent comme les plus corrélés à la perception de l’air fatigué.
    CONCLUSIONS: Parmi les groupes cliniques, les rides/texture et la ptose/relâchement sont les facteurs majeurs dans l’attribution d’un âge perçu pour les hommes chinois. L’air fatigué apparaît comme très fortement relié à l’âge apparent.
