The purpose of study was to scientiffically characterize the skin elasticity and slipping property on living body for cosmetic efficacy.
For this purpose, authors developed the measuring methods and instruments, corresponding to sensory skin evaluation of cosmetic users. The principle of each instrument is “suction cup” and “slip resistance” method. The measuring conditions were determined by the simulation of action for sensory skin evaluation.
The chart of skin elastometer denoted skin softness and skin elasticity. By this instrument, we measured the innerside of forearm of about 2000 women in several districts of Japan.
It was substantiated the mean skin softness of Kanto district was smaller than of Tohoku district, and the elasticity decreased with aging.
Moreover, the another instrument was useful for substantiation of cosmetic efficacy such as massaging.
