Plant vegetation is nature’s symphony, offering sensory experiences that influence ecological systems, human well-being, and emotional states and significantly impact human societal progress. This study investigated the emotional and perceptual impacts of specific monocultural vegetation (palm and rubber) in Nigeria, through audiovisual interactions using facial expression analysis, soundscape, and visual perception assessments. The findings reveal three key outcomes: (1) Facial expressions varied significantly by vegetation type and time of day, with higher “happy” valence values recorded for palm vegetation in the morning (mean = 0.39), and for rubber vegetation in the afternoon (mean = 0.37). (2) Gender differences in emotional response were observed, as male participants exhibited higher positive expressions (mean = 0.40) compared to females (mean = 0.33). (3) Perceptual ratings indicated that palm vegetation was perceived as more visually beautiful (mean = 4.05), whereas rubber vegetation was rated as having a more pleasant soundscape (mean = 4.10). However, facial expressions showed weak correlations with soundscape and visual perceptions, suggesting that other cognitive or sensory factors may be more influential. This study addresses a critical gap in soundscape research for monocultural vegetation and offers valuable insights for urban planners, environmental psychologists, and restorative landscape designs.

Background and Objectives: Facial beauty has attracted the attention of human societies for centuries, but there is not yet a common universal consensus on the perception of beauty. The first stage of facial analysis is a frontal examination of the face. Therefore, determining the morphometric characteristics of the face and facial organs will help to perceive the nuances that influence the aesthetics specific to each person. The aim of our study is to develop regression equations that will design personalized morphometric features for reconstructive and aesthetic applications that will adapt to each individual’s personal face and facial organs and incorporate cultural elements. Materials and Methods: The study was conducted with 100 volunteers, 50 males (mean age = 21.48 ± 1.54 years) and 50 females (mean age = 21.26 ± 0.66 years). We took facial photographs of the participants in the Frankfurt Horizontal plane so that measurements of the face and facial organs could be made on digital media. We measured forty parameters (eight for face, twelve for eyes, eight for nose, and twelve for lips). We used Image J (ver. 1.51) software for the measurements. We used SPSS Ver. 28.0 for the statistical analysis of the data. Results: As a result of the comparative statistical analysis, statistically significant (p < 0.05) differences were found between men and women in the F5—lower face height, E5—palpebral fissure height, E6—distance between the margin of the upper eyelid and the eyebrow, E8—distance between the midpoint of the eye and the edge of the lower eyelid, N3—alar width, and N5—nasal root angle variables. Conclusions: On the basis of the correlation analyses, linear regression equations were developed to estimate the ideal natural facial morphometry of men and women by the means of variables that were highly correlated with each other. The equations developed will estimate the optimum morphometric features of a person for natural harmony and balance between the face and facial organs in accordance with the individual’s population and gender. We believe that our study will guide medical professionals who perform cosmetic/aesthetic interventions and also inspire software or artificial intelligence applications related to facial or facial organ design.

Introduction: Facial aesthetics is an intricate domain bridging biology, psychology, and culture. It is influenced by evolutionary traits and societal norms, often driving demand for cosmetic treatments. While public perceptions of these interventions are widely studied, professional evaluations remain underexplored. This study examines differences in aesthetic judgement and treatment identification between healthcare professionals and laypeople, aiming to enhance clinical practice and research in facial aesthetics. Methods: A cross-sectional survey, administered via Microsoft Forms, assessed aesthetic evaluations from 88 participants, including professionals (e.g., dentists, dermatologists, and plastic surgeons) and laypeople. The survey comprised demographic questions, self-reported aesthetic assessment abilities, and visual evaluations of pre- and post-treatment images. Statistical analyses, including Fisher’s exact test and the Mann–Whitney U Test, evaluated associations between expertise level and judgments of facial beauty and treatment accuracy. Results: This study found no significant differences in subjective aesthetic improvement ratings between professionals and laypeople, suggesting that aesthetic judgments are inherently subjective. However, professionals demonstrated greater accuracy in identifying treatments in 3 of 7 cases (p < 0.05). Self-assessment revealed a critical disparity, with experts often underrating their skills compared to non-experts. Discussion: These findings highlight the interplay between expertise and subjectivity in aesthetic evaluations. While professional training enhances procedural recognition, biases influence judgement regardless of expertise. Incorporating standardised evaluation frameworks can refine aesthetic assessments across groups. Conclusions: This study underscores the value of expertise in treatment identification and advocates for standardised assessment methods to minimise bias, improve training, and support patient-centred aesthetic care.

This paper recounts the author’s reluctant journey of translating Matthew Fuller and Eyal Weizman’s Investigative Aesthetics: Conflicts and Commons in the Politics of Truth into Japanese, a process that turned out to be a mix of philosophical tightrope walking and comedic pratfalls. Along the way, we meet Baumgarten, the original translator who coined the aesthetica nomenclature, Kant, who insists that there can be no such thing as a science of sensibility, and a parade of Japanese translators who took great artistic liberties in rendering an alien term into a complicated language formed by three layers of different writing systems. The author reflects on his coining of a new translation for “aesthetics” in Japanese—Kansei-Jutsu (“Sensibility-Art”)—a term that baffled publishers, thrilled a few cultural studies scholars, and may have earned a side-eye from beauty salons already using “estetikusu” for facials. The translation saga spirals into debates about what “aesthetics” even means, culminating in a bittersweet realisation: translation is less about getting it right and more about sparking delightful, sometimes ridiculous, new ways of thinking. By the end, aesthetics re-emerges as a celebration of difference, proving that even conflicts can create a strange and wonderful commons when approached with an openness to diverse sensibilities.

This study examined the impact of males’ facial and vocal attractiveness, as well as social interest in females’ decision-making in a trust game. The results showed that trustees with attractive faces or expressing positive social interest were more likely to receive initial investments. Trustees with attractive voices also received more initial investments than unattractive ones in most conditions, except when they had attractive faces and positive interest. Moreover, participants reinvest in trustees with attractive faces or voices, even if they withheld repayment. However, trustees with positive interest would receive more reinvestment only when they reciprocated. In addition, trusters expressing positive social interest were expected to invest and earn repayment at higher rates. Nonetheless, trusters with attractive faces (or voices) were only expected to invest at higher rates when they had attractive voices (or faces) and negative interest. These findings suggest that beauty premium is modulated by participants’ roles, such that the effect of beauty would be stronger when participants encounter trustees rather than trusters. Positive social interest is a perk in most conditions, except when trustees withheld repayment. Full article

In Thailand, wild yam, or Dioscorea hispida Dennst., is a starchy crop that is usually underutilized in industry. The purpose of this study was to isolate the starch and extract the phytochemical from D. hispida and use them in cosmetics. Starch was used instead of talcum, which can cause pulmonary talcosis in dusting powder formulas (DP 1-5). GC-MS was used to identify the bioactive components present in the ethanolic extract of D. hispida. The main compounds were identified as 9,12-octadecadienoic acid (Z,Z)- (6.51%), stigmasta-5,22-dien-3-ol, (3.beta.,22E)- (6.41%), linoleic acid ethyl ester (5.72%), (Z,Z)-9,12-octadeca-dienoic acid, 2,3-dihydroxy-propyl (3.89%), and campesterol (3.40%). Then, the extract was used as an ingredient in facial sleeping mask gel formulas (SM 1–SM 5). Stability tests, physical characteristics, enzyme inhibitions, and sensitization dermal toxicity tests were used to evaluate the DP and SM formulations. The results showed that the fresh tubers of D. hispida showed a 12.5% w/w starch content. The findings demonstrated that starch powder had a restricted size distribution, ranging from 2 to 4 μm, and a smooth surface that was polygonal. Following stability testing, the color, odor, size, and flowability of all DP formulations did not significantly differ. The SEM investigation revealed that DP particles were homogenous. For the sensitization dermal toxicity test, DP denoted no erythema or skin irritation in the guinea pigs. After stability testing, the colors of the SM formulas were deeper, and their viscosity slightly increased. The pH did not significantly change. After the stability test, SM formulas that contained Glycyrrhiza glabra and D. hispida extracts exhibited stable tyrosinase and elastase inhibitory activities, respectively. In the sensitization dermal toxicity test, guinea pigs showed skin irritation at level 2 (not severe) from SM, indicating that redness developed. All of these findings indicate that D. hispida is a plant that has potential for use in the cosmetics industry. Furthermore, D. hispida starch can be made into a beauty dusting powder, and more research should be conducted to develop an effective remedy for patients or those with skin problems. Full article

Generative adversarial networks (GANs) are widely used in image conversion tasks and have shown unique advantages in the context of face image beautification, as they can generate high-resolution face images. When used alongside potential spatial adjustments, it becomes possible to control the diversity of the generated images and learn from small amounts of labeled data or unsupervised data, thus reducing the costs associated with data acquisition and labeling. At present, there are some problems in terms of face image beautification processes, such as poor learning of the details of a beautification style, the use of only one beautification effect, and distortions being present in the generated face image. Therefore, this study proposes the facial image beautification generative adversarial network (FIBGAN) method, in which images with different beautification style intensities are generated with respect to an input face image. First, a feature pyramid network is used to construct a pre-encoder to generate multi-layer feature vectors containing the details of the face image, such that it can learn the beautification details of the face images during the beautification style transmission. Second, the pre-encoder combines the separate style vectors generated with respect to the original image and the style image to transfer the beautification style, such that the generated images have different beautification style intensities. Finally, the weight demodulation method is used as the beautification style transmission module in the generator, and the normalization operation on the feature map is replaced with the convolution weight to eliminate any artifacts from the feature map and reduce distortions in the generated images. The experimental results show that the FIBGAN model not only transmits the beautification style to face images in a detailed manner but also generates face images with different beautification intensities while reducing the distortion of the generated face images. Therefore, it can be widely used in the beauty and fashion industry, advertising, and media production. Full article

Facial attractiveness, vocal attractiveness, and social interest influence two-person decision making. However, it remains unclear how these three factors jointly influence three-person bargaining. We investigated the impact of facial attractiveness, vocal attractiveness, and social interest on fairness decisions in a three-person ultimatum game and a third-party punishment dictator game. The results of the ultimatum game showed that in the condition of positive social interest, the acceptance rate of unfair/fair offers was higher when third players had attractive faces or attractive voices. Attractive faces of third players also increased acceptance rates of unfair/unfair offers than unattractive faces when third players expressed negative social interest. In the third-party punishment game, participants rated unfair allocations from unattractive-voice proposers with attractive faces (compared to unattractive faces) and proposers who expressed negative social interest (compared to positive social interest) as more reasonable. Regarding the punishment intentions, among the three factors, both the effect of vocal attractiveness and social interest were modulated by the combinations of the other two factors, while the effect of facial attractiveness remains robust across all conditions. These findings suggest that fairness decisions in three-person bargaining games are affected by beauty premium and social interest, while these effects vary across different decision contexts.

This paper proposes a new approach to pixel-level fusion using the opposite frequency from the discrete wavelet transform with Gaussian or Difference of Gaussian. The low-frequency from discrete wavelet transform sub-band was fused with the Difference of Gaussian, while the high-frequency sub-bands were fused with Gaussian. The final fusion was reconstructed using an inverse discrete wavelet transform into one enhanced reconstructed image. These enhanced images were utilized to improve recognition performance in the face recognition system. The proposed method was tested against benchmark face datasets such as The Database of Faces (AT&T), the Extended Yale B Face Dataset, the BeautyREC Face Dataset, and the FEI Face Dataset. The results showed that our proposed method was robust and accurate against challenges such as lighting conditions, facial expressions, head pose, 180-degree rotation of the face profile, dark images, acquisition with time gap, and conditions where the person uses attributes such as glasses. The proposed method is comparable to state-of-the-art methods and generates high recognition performance (more than 99% accuracy). Full article

The concept of gender has evolved significantly in recent decades, moving from a binary status to a multiplicity of gender types. In today’s world, the new reality of the concept of masculinity, as defined socially and historically, must be recognized and accepted by aesthetic medicine. Consequently, aesthetic doctors will have to adapt the views and treatment plans that they propose in their consultations to the ideals of beauty, as well as with the roles, behaviors, and attributes considered masculine within their society. Each facial feature suggests a personality characteristic that represents that individual. This expert opinion article aims to assess Caucasian male gender-related anatomical facial features and achieve an expert agreement on the association of specific features with the perception of attractiveness, masculinity, and personality traits in order to cover the wide range of current male representations, as well as to provide orientation for clinical practice improvement in the contemporary landscape of facial masculinization.

Background and Objectives: Facial symmetry is a key component of facial beauty and attractiveness. However, perfect symmetry is rare, and slight asymmetries, also known as natural asymmetries, are common and contribute to the uniqueness of each face. The perception of facial asymmetry varies among individuals and can be influenced by several factors. This study aimed to investigate the self-perception of dento-facial asymmetry among a sample of Romanian individuals, focusing on their awareness, the extent to which it bothers them, and their desire for correction. Materials and Methods: A cross-sectional analytical study was conducted with 283 participants from Romania between January and February 2024. Participants completed a questionnaire designed to assess their self-perception of facial asymmetry and socio-demographic characteristics. The questionnaire included 10 questions on self-perception of facial asymmetry and 8 questions on socio-demographic data. Statistical analysis was performed using SPSS 26.0, and the Pearson Chi-square test was used for comparative analysis. Results: The sample was predominantly female (75.3%) with an average age of 32.24 years. Most participants were from urban areas (80.6%) and had university degrees (58.7%). About 28.7% of participants observed facial asymmetry, with dental asymmetry being the most frequently reported, followed by asymmetries in the eyebrows and eyelids. The right side of the face was more commonly perceived as asymmetric. Although 24.4% of participants were bothered by their asymmetry, 39.2% expressed a desire to correct it. Conclusions: One-third of participants identified dento-facial asymmetry, with the dental level being the most reported. A significant portion of participants expressed a desire to correct their asymmetries, highlighting the importance of understanding self-perception in the context of facial aesthetics. This study underscores the subjective nature of facial asymmetry perception and the varying thresholds for what is considered bothersome or in need of correction. Full article

Acrylates and methacrylates, though common in a wide variety of products, especially in the dental industry, can cause adverse skin reactions. These compounds, including 2-hydroxyethyl methacrylate, triethylene glycol dimethacrylate, and bisphenol A-glycidyl methacrylate, are strong contact irritants or allergens. Found in dental prostheses, composite resins, dentin bonding materials, and glass ionomers, they pose a higher risk of exposure for dental personnel. Clinically, acrylate allergies manifest as facial rashes, eczema with cracked skin on fingers (pulpitis), nail dystrophy, and periungual dermatitis. Recently, however, the highest frequency of allergic reactions to acrylates has been observed in the beauty industry due to increased use in artificial nails, eyelashes, and hair extensions. This has led to greater sensitization. Acrylates are also used in medical applications such as bone cement for orthopedic endoprostheses, soft contact lenses, hearing aids, histological preparations, and wound dressings, which can also cause allergic reactions. For example, acrylates in surgical glue can cause severe dermatitis, and diabetic medical devices are also potential sources of allergic contact dermatitis. Given the extensive use and prolonged skin contact of products containing acrylates and methacrylates, this review aims to present current knowledge from the literature on reactions to these compounds across different industries.

Images, texts, voices, and signals can be synthesized by latent spaces in a multidimensional vector, which can be explored without the hurdles of noise or other interfering factors. In this paper, we present a practical use case that demonstrates the power of latent space in exploring complex realities such as image space. We focus on DaVinciFace, an AI-based system that explores the StyleGAN2 space to create a high-quality portrait for anyone in the style of the Renaissance genius Leonardo da Vinci. The user enters one of their portraits and receives the corresponding Da Vinci-style portrait as an output. Since most of Da Vinci’s artworks depict young and beautiful women (e.g., “La Belle Ferroniere”, “Beatrice de’ Benci”), we investigate the ability of DaVinciFace to account for other social categorizations, including gender, race, and age. The experimental results evaluate the effectiveness of our methodology on 1158 portraits acting on the vector representations of the latent space to produce high-quality portraits that retain the facial features of the subject’s social categories, and conclude that sparser vectors have a greater effect on these features. To objectively evaluate and quantify our results, we solicited human feedback via a crowd-sourcing campaign. Analysis of the human feedback showed a high tolerance for the loss of important identity features in the resulting portraits when the Da Vinci style is more pronounced, with some exceptions, including Africanized individuals.

Intradermal injection of bioactive compounds is used to reduce the effects of aging skin. The aim of this work is to study the response of facial injection of a hyaluronic acid complex supplemented with amino acids and antioxidant vitamins on skin rejuvenation. A total of 40 healthy adult subjects were recruited to whom this complex was injected into the facial skin, three consecutive times every two weeks. Together with assessing the degree of skin hydration, the level of skin microcirculation, wrinkles, skin color, and skin biomechanical parameters were evaluated. Using the GAIS scale, the degree of satisfaction of the participants was assessed. At 42 days (D42), there was an 11–12% increase in skin hydration and viscoelasticity, a 23% increase in skin density, a 27% increase in skin microcirculation, and a significant lightening and whitening of skin color, but without causing changes in skin wrinkles. A value between 1 and 3 on the GAIS scale was observed between 70 and 92% of the participants, and 87% of subjects found their skin more beautiful, 85% would recommend this treatment, and more than 50% found their face rejuvenated. In summary, the intradermal treatment tested suggests skin rejuvenation, with a good degree of safety. Full article

As a booming branch of online retailing, live-streaming e-commerce can present abundant information dimensions and diverse forms of expression. Live-streaming e-commerce has enabled online retailers to interact with customers face-to-face, resulting in widespread instances of emotional and impulse buying behavior. Prior research in live-streaming e-commerce has suggested that live streamers’ characteristics, especially the live streamer’s face, can affect customers’ purchase intentions. The present research used questionnaire surveys and an eye tracking experiment to investigate the impact of live streamer’s facial attractiveness on consumer purchase intention for search-based and experience-based products. The questionnaire survey analyzed 309 valid questionnaires and revealed that attractive faces are the key influencing factor driving consumers’ impulse purchase intentions. Moreover, consumers’ emotional experience plays a partial mediating role in the process of live streamers’ faces influencing purchase intention. The eye tracking experiment further explored the mechanism of a live streamer’s facial attractiveness on consumers’ purchase intentions of search-based products and experience-based products from the perspective of visual attention by analyzing 64 valid sets of data. The results showed that attractive faces attract more consumers’ attention and, therefore, increase their purchase intention. Furthermore, there is a significant interaction between product type, the live streamer’s facial attractiveness, and consumers’ purchase intentions. In the case of unattractive live streamers, consumers are more likely to buy search-based products than experience-based products, while the purchase intention does not vary between search-based products and experience-based products in the case of attractive live streamers. The present study provides evidence for ‘beauty premium’ in live-streaming e-commerce and sheds light on the design of the match between live streamers and different types of products. Full article
