The plasminogen/plasmin system in epidermis is thought to be the major protease involved in the delay of barrier recovery. However, little is known about the mechanism through which this system is activated. In order to clarify this mechanism, we first determined the distribution of proteolytic activity by using in situ zymography. As a result,(More)
We previously demonstrated that the skin surface electric potential, which has been long recognized as a parameter of emotional or physiological state, is generated by epidermal keratinocytes and is strongly associated with the ion concentration gradient in the epidermis. Thus, at temperatures below the threshold of sweating, the potential provides a(More)
Dear Editor, Enlarged, or dilated facial pores are one of the most frequently encountered skin problems in women of all ages. From our international survey, it has been revealed that more than half of women in their twenties and thirties complain of conspicuous pores. Because so little had been known about their anatomical structure, facial pores were(More)
We previously reported that skin surface electrical potential might be a good parameter of skin pathophysiology. To examine the potential availability of skin surface electrical potential measurement for diagnostic purposes, we measured the change of the potential in surfactant-induced dry skin and we compared the values of the potential in volunteers of(More)
BACKGROUND/PURPOSE Heterogeneity with respect to skin color tone is one of the key factors in visual perception of facial attractiveness and age. However, there have been few studies on quantitative analyses of the color heterogeneity of facial skin. The purpose of this study was to develop image evaluation methods for skin color heterogeneity focusing on(More)
