Patent number: 6269817Abstract: A cosmetic method for obtaining substantial cosmetic effects through simple massaging by ordinary people by first massaging in the direction of arterial blood flow and then in the direction of venous blood flow, or by massaging the surface of the skin with the use of a cosmetic comprising disintegrating particles while the pulse, dermal vasculature, skin temperature, or dermal blood flow is in a stimulated, dilated, elevated, or stimulated state as opposed to a resting state, and by washing the skin with a cleanser or a detergent, and then using a skincare cosmetic, wherein massaging is done using a massaging cosmetic comprising disintegrating particles before the skincare cosmetic is used after washing with a cleanser or detergent. This allows effective skincare to be achieved.Type: GrantFiled: September 21, 1998Date of Patent: August 7, 2001Assignee: Kao CorporationInventors: Yoshinao Nagashima, Takahide Minami, Yukihiro Yada

Patent number: 5991433Abstract: A method and apparatus for analyzing skin surface conditions which includes transferring horny cells from a skin surface of a subject onto an adhesive face of a base sheet. In addition, a learning-type image measurement system equipped with autocorrelation mask patterns is executed on a morphology of the horny cells in the image, thus judging at least one of a degree of overlapping, a degree of ellipticity and a degree of area of the horny cells. Further, the skin surface conditions are analyzed using this information.Type: GrantFiled: May 22, 1997Date of Patent: November 23, 1999Assignee: KAO CorporationInventors: Osamu Osanai, Yukihiro Yada, Shuichi Akazaki
