PROBLEM TO BE SOLVED: To provide a measuring method for precisely estimating a skin age becoming the index of aging of the skin on the basis of mechanical impedance property, and an apparatus for measuring the skin age. SOLUTION: Compressed air is jetted from a nozzle 7 toward a skin surface (p), deformation of the skin surface in that case is detected by a displacement sensor 8, and a detected value is data-processed by a PC to calculate the mechanical impedance property. Next, on the basis of the elastic item parameter k2 of the mechanical impedance property, the skin age is calculated, or the most approximate age is deduced from a correspondence table. The deduced age is displayed as the skin age. In place of the elastic item parameter k2, a C/K value obtained by normalizing a composite viscosity parameter C with a composite elasticity parameter K can be used. COPYRIGHT: (C)2007,JPO&INPIT
