The appearance of skin is one of the critical research targets in cosmetology since cosmetics are key items for improving or controlling skin appearance. Therefore, a lot of studies on skin appearance have been carried out for the development of cosmetics. Such previous cosmetic studies are roughly subdivided into several approaches: psychology-based, optics-based, and image-based ones. An approach based on visual information processing is also important, especially when the mechanism of the appearance perception is investigated. In these approaches, the optics-based one has the advantage of identifying the skin optical properties (e.g. reflection, translucency, and spectral properties) that relate to the features of the targeted appearance. The image-based approach has the advantage of identifying visual cues that induce the features of the targeted appearance. Since such optical properties and visual cues are crucial information for designing formulations and ingredients of cosmetics, studies on the skin appearance based on optics and image have been frequently carried out. In this paper, to begin with, the above-mentioned approaches are overviewed. Then, more details regarding the optics-based and image-based approaches are argued. Finally, some of the previous studies on the development of cosmetic ingredients for controlling the skin appearance, which employed opticsand image-based approaches, are reviewed.

Dullness of the skin around the eyes is one of the most serious cosmetic problems. However, the causative mechanism of skin dullness, especially in the skin of the upper eyelids, remains unclear, and effective treatment needs to be established. The skin of the upper eyelids is particu-larly exposed to mechanical stimulation such as compression or friction by repetitive and multiple applications or removals of make-up. Mechanical stimulation has already been reported to induce hyperpigmentation of the skin. We hypothesized that dullness of the skin of the upper eyelids might be caused by melanin formation through mechanical stimulation. We conducted two ex-periments using reconstructed human skin models; the first experiment showed that repetitive loadings of weight resulted in the activation of melanogenesis, and the second one demonstrated that the activation of melanogenesis was inhibited by the addition of a nitric oxide scavenger. These results suggest that nitric oxide is involved in mechanical stimulation-induced melanogenesis. In addition, a skin lotion containing nitric oxide scavenging preparation, wasuregusa flower ferment filtrate, did not reduce the dullness of the skin of the cheeks, where the relative frequency of mechanical stimulation is low, but did reduce that of the upper eyelids. These results support our hypothesis that mechanical stimulation contributes to the dullness of the skin of the upper eyelids and suggest that nitric oxide plays an important role in mechanical stimulation-induced melanogenesis. Therefore, nitric oxide and its generation need to be targeted to reduce skin dullness.

In recent years, hair damage by sunlight and chemical treatment such as perming and bleaching has become a consumer concern. It is important to understand the effect of sunlight and chemical treatment on hair microstructure to develop the technology for protection and repair of hair. Our previous study demonstrated that a differential phase contrast scanning X-ray microscopy was a useful nondestructive analysis method to observe internal hair structure with high-resolution. In this study, hair samples with three different chemical treatment （ normal, perming and bleaching ） and additional irradiation by artificial sunlight were observed with a scanning X-ray microscopic tomography system using a synchrotron radiation light source in order to understand the damag-ing effect of both sunlight and chemical treatment on hair. The porosity rate in the cortex is higher in the permed hair than normal hair and void distribution in the cross section of permed hair is localized. The porosity rate in the cortex of permed hair is decreased by additional irradiation. The porosity rate of bleached hair is the same as that of normal hair and isn ʼ t changed by the irradiation. These results suggest that hair microstructural change in the cortex by sunlight is affected by the prior chemical treatments, and development of varied protection and repair technology de-pending on the prior treatment situation is needed.

Market volume of sensitive skin care products has continuously increased along with the increase in people’s concern about sensitive skin due to more stressful lifestyles and environmental degradation. We investigated whether dipotassium glycyrrhizate （DPG）, the active ingredient which is most frequently utilized in sensitive skin care products in Japan, is able to reduce the expression of nerve growth factor （NGF）, which upregulates hyperesthesia in the skin, a characteristic condition of sensitive skin, with an in vitro study. Furthermore, suppression effects in some parameters of sensory discomfort were found in a human stinging test using a formulation containing 5％ lactic acid and with／without 0.2％ DPG. In this study, DPG suggested the possibility of improvement for persons with various kinds of sensitive skin.

Many bioengineering techniques to elucidate functions and characteristics of the skin have been developed. They measure such factors as the water content of the stratum corneum, transepidermal water loss （ TEWL ） , skin surface contour, mechanical properties, blood flow, sebum secre-tion rate, wrinkles, skin pigmentation, and so on. These instrumental measurements are applied to validation of the efficacy of the cosmetics. Recently, a few in vivo bio-microscopes which non-invasively visualize horizontal images or vertical cross sections of the skin with subcellular reso-lution, have been developed by using the non-linear optics phenomenon. In this paper, I review the skin measurement technologies that have been used for cosmetics efficacy test, and also describe in vivo bio-microscopes, which include optical coherence tomography （ OCT ）， the confocal laser scanning microscope （ CLSM ） , the second harmonic generation （ SHG ） microscope, the multi photon microscope （ MPM ） , and coherent anti-Stokes Raman scattering （ CARS ）， which will be very helpful to examine the effects of cosmetics on the skin.
