Objective To assess the impacts of sun exposures on some skin signs on the faces and hands of differently aged Japanese women, according to their distinct behaviours towards vis à vis sun exposure. Methods Two comparable cohorts of Japanese women (aged 18–83 years) were created according to their usual behaviour towards sun exposure i.e. non‐sun‐phobic (N = 495) and sun‐phobic (N = 516) and through their regular use(s) of a photo‐protective product. Standard photographs (full‐face and 45° lateral) allowed to focus on 18 facial signs that were graded by 15 experts, using a referential skin ageing Atlas. From these two cohorts, two sub‐cohorts (114 and 122 women) were created with regard to the similar clinical aspects of the dorsal side of their hands (Left vs. Right) that were further graded. Absolute differences in the scores of each sign were used (non‐sun‐phobic minus sun‐phobic), by age‐ranges, to better ascertain the impact of sun exposures and photo‐protection. Results Facial signs related to skin wrinkles/texture and pigmentary spots were found significantly more accentuated among non‐sun‐phobic women and show an early onset (20–30 years). Facial sagging and crow’s feet wrinkles appear delayed (30–40 years). The severity of vascular disorders was found to be similar in the two cohorts. The absolute differences in the grading’s of almost all signs were unsurprisingly found increased with advancing ages, illustrating the combination of chronological and photo‐ageing processes. With regard to hands, differences in skin texture and pigmentary disorders are of a late onset (40–50 years) and were found much increased at older ages. The cutaneous signs of the hands of Japanese women can hardly be taken as reliable markers of their photo‐ageing status. Conclusion The present work illustrates, for the first time, some specificities of the impact of sun exposures on the facial skin of Japanese women, pinpointing the fact that some facial signs are of an early onset. Results significantly confirm the importance of both sun avoidance coupled with photo‐protective measures.

Objectives: (a) To assess and compare the changes in five facial signs with age between genders of Caucasian subjects and (b) to evaluate their links with perceived ages and tiredness. Material and Methods: Once zoomed from standardized digital photographs, five facial signs of 518 Caucasian French subjects of both genders and different ages (18-69 years) were graded by 15 experts, using a referential Skin Aging Atlas. A large naïve panel of 1000 French subjects (500 men and 500 women) was asked to attribute a perceived age and a degree of tiredness to 200 subjects (among the 518). Results: The severity of the facial signs increases with time at a linear-like rate. The changes in marionette lines significantly differ between genders, much more pronounced in women, and nasolabial fold was found more pronounced in men at older ages (>50 years). Before 50's, Forehead wrinkles present a slightly higher severity in men whereas at 50's women present more severe ptosis. Crow's feet wrinkles did not show significant changes. Perceived ages were found significantly correlated with the severities of the facial signs and the perception of tiredness was associated with perceived ages in men, but not in women older than 40 years. The gender-related perceptions from the naïve panel in both perceived ages and tiredness showed a low discrepancy. Interestingly, as for changes in facial signs, the upper-half face seems more affected for men and lower-half face for women; after 40 years, the naïve panel seems more focusing on the same areas to predict a perceived age. Conclusion: As compared to the previous Chinese study, the present work reveals some slight ethnical-related differences, indicating that the facial signs of the lower face play a major role in the assessment of perceived age of both genders from different ethnicity.

A sensory descriptive method is used by the industries to characterize their various products under development. The sensory panelists are recruited through some general criteria suggested in International Standard Sensory Analysis-General guidelines for the selection, training and monitoring of selected assessors and expert sensory assessors [5] but for hair product evaluation, some hair criteria should also be considered, as a major challenge lied in the difficulty to recruit panelists. Such an issue led us to find practical solutions to make this recruitment easier. Among others, one possible solution was to restrict some requirements in the characteristics of hair. This study aimed at checking if a hair type diversification on either sensitization or curliness could influence the sensory perception of shampoos, and, if so, to which extent. This study demonstrates that, for a shampoo trained panel, the evaluation is impacted by the hair curliness but is not impacted by the hair sensitization level. R esum e Une m ethode de description des sensations est utilis ee par les industries pour caract eriser leurs diff erents produits en cours de d eveloppement. Des membres sont recrut es pour un panel en se basant sur certains crit eres g en eraux sugg er es dans la Norme Internationale d'Analyse sensorielle-Directives g en erales pour la s election, la formation et la supervision des evaluateurs s electionn es et des evaluateurs sensoriels experts [5], mais pour l' evaluation des cheveux, certains crit eres doivent egalementêtre pris en compte, car une des principales difficult es consiste a recruter des pan elistes. Ce probl eme nous a oblig e de trouver des solutions pratiques pour faciliter ce recrutement. Entre autres, une solution possible etait de limiter certaines exigences au niveau des caract eristiques des cheveux. Cette etude vise a v erifier si la diversit e au niveau de la sensibilit e ou de la frisure de la chevelure pourrait influencer la perception sensorielle des shampooings, et, si c'est le cas, dans quelle mesure. Cette etude d emontre que, pour une palette de 6 shampooings d evelopp es, l' evaluation est impact ee par la frisure de la chevelure7mais n'est pas impact ee par le niveau de sensibilit e.
