Abstract and Figures

Background: The recent COVID-19 pandemic has generalized the use of face mask in public area, and it is now common to wear it for long hours. But face mask interfere with cosmetics, and key concerns for tinted products are staining of the mask and degradation on face. Consumers have modified beauty routine by a decrease of makeup, but are now expecting new products adapted to face mask. Little is known about the mechanisms that affect most the makeup under the face mask, so that further studies are needed to develop adequate evaluation methods and products. In this study, the color transfer on mask and makeup degradation on face are assessed through a mixed approach of consumer and instrumental evaluation. Materials and methods: Two tinted face products (A and B) were applied by half face on 11 Japanese women, who conducted real-life activities with a face mask during 4 hours. Panelists evaluated the stain of their face mask by visual assessment, while the makeup degradation on face was evaluated by color measurement by instrumental method. Results: No difference was observed between the two products for lasting on face, but consumer evaluation showed a better resistance of product A for color transfer on mask. Conclusion: The mix of instrumental and consumer evaluation is a promising way to evaluate the makeup degradation on face and color transfer on mask, which are two key factors to develop mask resistant makeup products.

1 | INTRODUCTION
The use of face mask has increased worldwide due to the recent
COVID- 19 pandemic. To control the number of infections, the World
Health Organization now recommends the use of mask, especially
in closed spaces such as working offices, schools, grocery stores, or
public transportations.1 As this pandemic is not expected to stop
soon,2 wearing the mask for long hours is becoming a new standard
of life.
The biophysical effects of wearing a face mask are multiple. To
cite a few, previous studies found that the increase of temperature
and humidity under the mask af fects the heart rate and exertion

Abstract
Background: The recent COVID- 19 pandemic has generalized the use of face mask
in public area, and it is now common to wear it for long hours. But face mask inter-
fere with cosmetics, and key concerns for tinted products are staining of the mask
and degradation on face. Consumers have modified beauty routine by a decrease of
makeup, but are now expecting new products adapted to face mask. Little is known
about the mechanisms that affect most the makeup under the face mask, so that
further studies are needed to develop adequate evaluation methods and products. In
this study, the color transfer on mask and makeup degradation on face are assessed
through a mixed approach of consumer and instrumental evaluation.
Materials and Methods: Two tinted face products (A and B) were applied by half face
on 11 Japanese women, who conducted real- life activities with a face mask during
4 hours. Panelists evaluated the stain of their face mask by visual assessment, while
the makeup degradation on face was evaluated by color measurement by instrumen-
tal method.
Results: No difference was observed between the two products for lasting on face,
but consumer evaluation showed a better resistance of product A for color transfer
on mask.
Conclusion: The mix of instrumental and consumer evaluation is a promising way to
evaluate the makeup degradation on face and color transfer on mask, which are two
key factors to develop mask resistant makeup products.

... In always wearing a mask, a higher proportion of females felt stressed compared with males. This may be because make-up adheres to the mask and make-up is spoiled [42]; in addition, hairstyles do not last well under the moisture from wearing the mask [43], and females report feeling stress from this. ...
Psychological and Physical Changes Caused by COVID-19 Pandemic in Elementary and Junior High School Teachers: A Cross-Sectional Study
Article
Full-text available
This study aimed to determine psychological and physical differences in elementary and junior high school teachers during COVID-19. This questionnaire-based cross-sectional study was conducted among 427 teachers in Tokyo, Japan (between 15 and 30 October 2020). The questionnaire explored school type (elementary and middle schools), sex, age, and COVID-19 changes (psychological changes, physical changes, impact on work, and infection control issues perceived to be stressed). Post hoc tests for I cannot concentrate on work at all, found a significant difference for no change–improved and male teacher in elementary school female teacher in junior high school (p = 0.03). Regarding stress situation due to implementation of COVID-19 infection control, there were significant differences for disinfection work by teachers between male teachers in elementary school female teachers in junior high school (p = 0.04) and female teachers in elementary school female teachers in junior high school (p = 0.03). COVID-19 produced differences in psychological and physical changes between male and female teachers in elementary and junior high schools. Some experienced psychological and physical stress, whereas others showed improvement. Given that teachers’ mental health also affects students’ educational quality, it is important to understand and improve teachers’ psychological and physical circumstances and stress.

Can nasal filters be used to reduce personal exposure against nano- to submicron-sized environmental tobacco smoke (ETS) aerosols?
Article
  • Jun 2022
Environmental tobacco smoke (ETS) contains large amounts of nano- to submicron-sized aerosols, which can be suspended in the indoor air for a long time and are easily inhaled by nonsmokers causing various diseases. In recent years, various types of nasal filters have been increasingly emerging on the market, claiming to be effective in filtering ETS aerosols. In order to test the real protection level of those nasal filters, this study independently builds a nasal filter simulation test system, separately takes mainstream smoke (MS) and sidestream smoke (SS) aerosols as the test mediums (ETS consists of MS and SS), and comprehensively tests the filtration efficiency, inspiratory resistance and quality factor of five nasal filters (four commercially available and one self-made from N95 filtering facepiece respirator) at two flow patterns (constant flow and simulated human breathing flow) and three flow rates (15, 30 and 50 L/min). Results show that the filtration efficiencies of the four commercial nasal filters are all less than 20% for both MS (98% aerosols lie in 85–380 nm) and SS aerosols (94% lie in 65–200 nm), while the inspiratory resistance analysis confirms that to avoid open-mouth breathing, the tested nasal filters can only be used at rest or during light activity. The findings reveal that, to effectively protect against ETS aerosols, manufacturers should further develop high-efficiency nasal filters with low-resistance. This study may serve as a reference for establishing testing standards on nasal filters. Copyright © 2022 American Association for Aerosol Research

Japanese experiment of a complete and objective automatic grading system of facial signs from selfie pictures: Validation with dermatologists and characterization of changes due to age and sun exposures
Article
Full-text available
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. Conclusion 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.

Effect of face mask on skin characteristics changes during the COVID‐19 pandemic
Article
Full-text available
Background Previous studies have demonstrated the possibility of adverse effects of prolonged wearing of personal protective equipment in healthcare workers. However, there are a few studies about the effects on skin characteristics after wearing a mask for non‐healthcare workers. In this study, we evaluated the dermatologic effects of wearing a mask on the skin over time. Materials and Method Twenty‐one healthy men and women participated in the study. All participants wore masks for 6 hours consecutively. Three measurements were taken (a) before wearing the mask, (b) after wearing the mask for 1 hour, and (c) after wearing the mask for 6 hours. Skin temperature, skin redness, sebum secretion, skin hydration, trans‐epidermal water loss, and skin elasticity were measured. Results The skin temperature, redness, hydration, and sebum secretion were changed significantly after 1 and 6 hours of wearing a mask. Skin temperature, redness, and hydration showed significant differences between the mask‐wearing area and the non–mask‐wearing area. Conclusion Mask‐wearing conditions and time can change several skin characteristics. In particular, it is revealed that the perioral area could be most affected.

Impact of the COVID-19 pandemic on sports and exercise
Article
Full-text available
  • Jul 2020
COVID-19 is a droplet-transmitted potentially fatal coronavirus pandemic affecting the world in 2020. The WHO recommended social distancing and human-to-human contact was discouraged to control the transmission. It has put many countries in a state of lockdown and sporting events (including the 2020 Olympics) have been affected. Participation in sports and exercise, typically regarded as healthy activities, were also debated. The local professional football leagues, governed by the Hong Kong Football Association, ultimately postponed all matches after much deliberation on the transmission risk for the spectators and on-field players. Large spectating crowds are well-known to be infectious hazards, but the infection risk for on-field players is less recognized. To address this question, we performed a small-scale investigation that showed, in a 90 min match, the average duration of close contact between players was 19 min and each player performed an average of 52 episodes of infection-risky behaviours. This suggests that the infection risk was high for the players, even without spectators. Aside from watching professionals exercise, many people opted to hike in the countryside during the weekends to avoid city crowds. This led to a widespread discussion on the issue of masked versus unmasked hiking. We performed a laboratory study to investigate the physiological effect of wearing a facemask during simulated hiking and found that it significantly elevated heart rate and perceived exertion. The clinical implication is that hikers need to realize masks increase the physiological burden, especially in those with multiple underlying comorbidities. Elite athletes, especially those training for the upcoming Olympics, needed to balance and reschedule their training regime since the risk of deconditioning versus the risk of infection was a genuine dilemma for themselves and their team. We described the multiple infection-control measures imposed by the national team training centre to help strike this balance. Amidst a global pandemic affecting millions; staying active is good, but staying safe is paramount.

The continuous development of a complete and objective automatic grading system of facial signs from selfie pictures: Asian validation study and application to women of three ethnic origins, differently aged
Article
Full-text available
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. Conclusion 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.

Role of make-up in the context of Covid-19?
Article
Full-text available
  • Jul 2020
Abstract: Covid-19 has had a significant impact on both make-up sales and traditional business set-up. With virtual meetings becoming the new norm, a pilot exploratory investigation was conducted to probe the relevancy of make-up whilst working from home via online platforms. An eye-tracking device was used to record the time viewed (seconds), fixation (frequency) and revisits (frequency) of the audience on models wearing make-up or not, during video calls. Results showed that an increase in gaze can be conveyed by a webcam whilst wearing make-up, which can lead to heightened attentiveness from the audience. The application of lip colour seemed to catch the attention of the gaze earlier and to divert audience attention downwards from higher areas of the face. Opportunities to revamp claims for colour cosmetic products following the impact of Covid-19 is also discussed.

Facial Skin Temperature and Discomfort When Wearing Protective Face Masks: Thermal Infrared Imaging Evaluation and Hands Moving the Mask
Article
Full-text available
Individual respiratory protective devices and face masks represent critical tools in protecting health care workers in hospitals and clinics, and play a central role in decreasing the spread of the high-risk pandemic infection of 2019, coronavirus disease (COVID-19). The aim of the present study was to compare the facial skin temperature and the heat flow when wearing medical surgical masks to the same factors when wearing N95 respirators. A total of 20 subjects were recruited and during the evaluation, each subject was invited to wear a surgical mask or respirator for 1 h. The next day in the morning at the same hour, the same subject wore a N95 mask for 1 h with the same protocol. Infrared thermal evaluation was performed to measure the facial temperature of the perioral region and the perception ratings related to the humidity, heat, breathing difficulty, and discomfort were recorded. A significant difference in heat flow and perioral region temperature was recorded between the surgical mask and the N95 respirator (p < 0.05). A statistically significant difference in humidity, heat, breathing difficulty, and discomfort was present between the groups. The study results suggest that N95 respirators are able to induce an increased facial skin temperature, greater discomfort and lower wearing adherence when compared to the medical surgical masks.

COVID-19 Pandemic & Skin Care Guidelines for Health Care Professionals
Article
Full-text available
  • May 2020
The Novel corona virus is bringing multiple challenges for health care professionals. Skin is the biggest organ and the first line of defense against different infections and external factors. Being the front line warriors, health care professionals are susceptible to various skin conditions due to prolonged use of personal protective equipment. These adverse skin conditions are redness, irritation, itching, contact dermatitis, and aggravation of underlying skin conditions like seborrheic dermatitis and acne vulgaris. In the current global situation, the potential incidence of such adverse dermatological effects does not in any manner cause the HCPs to deviate from the strict specific precautionary hygiene rules. These skin problems are manageable with the few precautionary measures. This article explores the different skin conditions that result from personal hygiene measures and usage of protective gear and will suggest some practical advice about how to manage and protect from these different adverse skin conditions. doi: https://doi.org/10.12669/pjms.36.COVID19-S4.2748 How to cite this:Masood S, Tabassum S, Naveed S, Jalil P.

Seborrheic dermatitis and masks
Article
  • Aug 2020
In Milan, Italy, after the end of the lockdown period (March and April 2020), we observed several patients with seborrheic dermatitis (SD) who showed a more or less important worsening of their disease. All patients used anti‐coronavirus‐19 (COVID‐19) face mask for many hours per day. According to the clinical point of view, the worsening was characterized by increased erythema and desquamation as well as itching worsened. In the last few weeks, some articles have been published on cases of dermatitis of the face associated with the use of anti‐COVID‐19 masks. Some authors hypothesized that this condition is due to high temperature of the face covered by the mask, that induces an increased sebum excretion rate. In our patients with SD, it is possible that high temperature of the face induces abnormalities of microbiota (proliferation of Malassezia spp.?) and permeability of skin barrier, and increases sweating with irritant action and worsening of itching.

Short‐term Skin Reactions Following Use of N95 Respirators and Medical Masks
Article
  • May 2020
Background: In the context of the COVID-19 pandemic, cases of adverse skin reactions related to the wearing of masks have been observed. Objectives: To analyze the short-term effects of N95 respirators and medical masks, respectively, on skin physiological properties and to report adverse skin reactions caused by the protective equipment. Methods: This study used a randomized crossover design with repeated measurements. Twenty healthy Chinese volunteers were recruited. Skin parameters were measured on areas covered by the respective masks and on uncovered skin 2 and 4 hours after donning, and 0.5 and 1 hour after removing the masks, including skin hydration, transepidermal water loss (TEWL), erythema, pH, and sebum secretion. Adverse reactions were clinically assessed, and perceived discomfort and non-compliance measured. Results: Skin hydration, TEWL, and pH increased significantly with wearing the protective equipment. Erythema values increased from baseline. Sebum secretion increased both on the covered and uncovered skin with equipment-wearing. There was no significant difference in physiological values between the two types of equipment. More adverse reactions were reported following a N95 mask use than the use of a medical mask, with a higher score of discomfort and non-compliance. Conclusions: This study demonstrates that skin biophysical characters change as a result of wearing a mask or respirator. N95 respirators were associated with more skin reactions than medical masks.

A new procedure, free from human assessment, that automatically grades some facial skin signs in men from selfie pictures. Application to changes induced by a severe aerial chronic urban pollution
Article
  • Jan 2020
  • Int J Cosmet Sci
Objective: These were two folds: At first, to develop an automatic grading system specifically dedicated to some facial signs of men, similarly to the one previously validated on women of different ethnic ancestry. Second, to assess its potential in detecting and grading the possible impacts of a severe aerial urban pollution on some facial signs of Chinese men. Methods: In both studies, selfies images were obtained from differently aged men. Nine facial signs were automatically graded through a specific A.I-based algorithm and clinically assessed by a panel of experts and dermatologists. Selfies pictures were taken from individual smartphones of variable optical properties. First study, designed for developing an automatic grading system, involved three comparable cohorts of men from three different regional ancestries (African, Asian, Caucasian, 110 each) the selfies images of which were acquired under four different lighting conditions. As a second use case study, the facial signs of two cohorts of Chinese men (101 and 100, each), differently aged, regularly exposed to very different aerial urban pollution conditions (UP) were analyzed by the same algorithm, selfies being taken under only one lighting condition. Results: - The new automatic grading system of facial signs suits well to men, showing comparable results than that the one dedicated to women and provides data in close agreement with experts' assessments. - In both cases (expert's or automatic methodology), the accuracy of the scores appeared ethnic-dependent. - The applied case confirmed previous results obtained clinically, i.e. that many facial signs were found of an increased severity among men exposed to a severe urban pollution, as compared to those living in a less polluted city. - In both studies, statistical agreements between the automatic grading system and expert's assessments were reached. In some facial signs, the automatic grading system seems offering a slightly better accuracy than the assessments made by the experts. Conclusion: Apart from some minor limitations, this A.I-based automatic grading system, free from human intervention, performed as well as the one previously developed in women, in close agreement with expert's assessments. In epidemiological studies, this system offers an easy, fast, affordable and confidential approach in the detection and quantification of male facial signs.
