Glossiness is one of the most important quality components of lip rouge. However, an objective and quantitative evaluation method has yet to be established. We aimed to develop a method for image-based lip glossiness measurement by focusing on the texture design of lip rouge, including “ pearly ” and “ glossy ” textures. Initially, the correlation between visual glossiness and the image statistic parameter “ skewness ”， which has been used in previous glossiness perception studies, was evaluated. Skewness showed a good correlation with the visual glossiness of glossy texture lip rouge （ correlation coefficient r ＝ 0.65 ）， though not with that of pearly texture lip rouge （ r ＝ 0.21 ）． Next, we developed a new image statistic parameter termed “ RMS contrast ”， which was consid-ered to have a good correlation with the visual glossiness of pearly texture lip rouge. To evaluate the efficacy of RMS contrast, image statistic parameters and visual glossiness scores of texture-enhanced lip rouges （ glossy, pearly, and matte ） were determined and compared. The present re-sults showed that skewness showed a good correlation with the glossiness of glossy lip rouge, while RMS contrast showed that with pearly lip rouge. In addition, use of a multiple regression equation with these two image statistic parameters allowed for effective evaluation of visual glossiness with good estimation accuracy （ r ＝ 0.82 ）．

Silk is one of the main ingredients in cosmetics, and its function is skin moisturization and protection of both hair and skin. In this study, a silk nanofiber suspension was prepared using a wet high pressure jet mill, and its properties were evaluated. The suspension was dried and observed using field-emission scanning electron microscopy, and its specific surface area was measured using the Brunauer-Emmett-Teller （ BET ） method. For these results, it was confirmed that the silk was in the form of nanofibers. The silk nanofiber suspension was then mixed with cellulose nanofibers or a carbomer, and changes in its viscoelastic properties were measured. When only a small amount of cellulose nanofibers was added, the viscosity of the suspension increased, but no precipitation was observed. In the case of the suspension being mixed with a carbomer, a silk nanofiber gel could be easily prepared. It was found that prototype cosmetics to which silk nanofibers were added could retain skin moisture for a longer time than those without silk nanofibers.

The texture of powder cosmetics, such as “ smoothness ” and “ moist feeling ”， is one of the most important properties for a usability assessment. In general, we rely upon a sensory evaluation to assess the usability of cosmetics. However, such subjective evaluation tends to be vague, not only due to the lack of evaluators ʼ skill but also due to the reproducibility error of environmental factors. Therefore, a highly reliable and efficient evaluation method using physical properties has been in demand. In the fields where powder products are handled, such as the pharmaceutical and food industries, the direct shear testing of the powder bed （ DST ） has been applied for evaluating the powder ʼ s flowability, as an important physical property in the filling process. In this study, the correlation between sense of use and physical properties was investigated by DST for powder ingredients and powdery foundations. As a result, it was found that the internal friction coefficient m i was correlated with “ smoothness ”， while the shearing cohesion t c was related to “ moist feeling ”． This evaluation method can be applied to powder ingredients as well as to molded powders. Fur-thermore, this method can precisely detect the differences in texture between powdery foundations obtained from different molding processes （ i.e. dry and wet molding processes ）．

While one’s first impression is clearly influenced by his/her facial features and expressions, the texture of facial skin is also an important factor that determines such impressions. We focused on the middle-aged males’ wishes that they be seen as appropriately aged and youthful. We therefore attempted to investigate what governs the impression of youthful appearance. Examining visually, we confirmed that apparent age was related to “Wrinkle” evaluation scores whereas youthful impression was related to “Spot”, “Blood color”, and “Dull color of skin” evaluation scores. Furthermore, based on eye-tracking measures, the facial portion where remarkably longer gaze durations were observed for “youthfulness impression evaluation” as compared to “apparent age evaluation” was found to be the cheek, where skin quality is most likely discernible. When middle-aged males repeatedly used a model emulsion, their youthful impression increased only from short distances, where the skin could be well-observed. For middle-aged males who have experienced age-related changes in skin quality, daily skincare is an effective means of promoting a youthful impression.
