AGE-RELATED FACIAL WRINKLING 385 The Caucasian females showed significantly higher wrinkle scores than the Japanese females in the eight evaluated areas of the face in the groups aged 20-29 years marked increases in wrinkles in the lower eyelid, and especially marked increases in wrinkles in the nasolabial groove, cheek, and corner of the mouth, which are considered to be due to subzygomatic sagging, in the groups aged 40--49 years or more and a significantly higher sagging score in the groups aged 40--49 years or more.

Sci., 55, 387-391 Quly/August 2004) Abstracts Journal of the Society of Cosmetic Chemists Japan Vol. 37, No. 3, 2003* Skin Surface Friction and Sensory Evaluation Mariko Egawa, Tetsuji Hirao, Motoji Takahashi Shiseido Life Science Research Center Sensory properties are very important in efficacy tests of cosmetic products. Several devices for the measurement of tactile sensory properties have been developed in recent years, and we have studied skin surface friction and examined the correlation with skin physiological parameters. The purpose of this study was to determine the relationship between skin frictional parameters and sensory evaluation after application of cosmetics. A KES-SE Frictional Anal yz er (Kato Tech Co. Ltd., Japan), a commercial device for the measurement of surface instrumental analysis may be useful to predict the tactile impression of cosmetics on human skin. Efficiency Characterization Index for Constituents in External Preparations on Wound Healing Hajime Shimomura, Kazuo Izawa, Hiroshi Tachi, Toshiaki Sugiyama Department of Research and Development, Mikimoto Pharmaceutical Co., Ltd. Department of Chemistry and Biochemistry, Suzuka National College of Technology frictional characteristics, was used in this study. An arm The healing effect of local preparations containing bovine holder was added to this device for measurement on the blood or hydrocortisone was examined on open wound of human forearm. Frictional coefficient (1vfiU) and its mean rat skin. The wounds were produced by application of deviation (MMD) were used as parameters of surface lOmm-diameter-punch. The wound areas were copied to friction. The moisture content in the stratum comeum was transparent film and were measured with an image analyzer measured with a Corneometer CM825. MIU and MMD every day. From the results of our experiment, it was were measured immediately, and at 1.5, 4, 5.5 and 7 h after demonstrated that the rate of wound healing became application of 9 kinds of moisturizing emulsion with smaller with decreasing wound area. And in this study, the different textures, and the sensory evaluation was made by cell division rate h was found to be an indicative parameter 6 experts and 149 consumers at almost the same time as the of wound healing rate. frictional measurement. In the comparison of sensory score with frictional properties, MIU showed a high positive correlation coefficient with hydrate, oily and sticky, while inversely with slippery and dry. It was also shown that oily (aburapposa in Japanese) and hydrate (shittori in Japanese) properties of cosmetics could be examined separately using MIU and MMD. In addition, the changing pattern of MIU with time after application of cosmetics to skin was correlated with fit (najimi in Japanese) assessment.
