Överskrift An analysis of the reduction of elasticity on the ageing of human skin and the recovering effect of a facial massage
Beskrivning Based on a study of human hand movements during practical diagnosis, evaluation patterns of softness and elasticity were observed. The evaluation models were extracted from these analyses and applied to the developing a method of detecting the dynamic properties of human skin. The device consisted of a robot arm controlled by microcomputer system and a probe with a mounted mechanical strain gauge. A method was developed to measure the dynamic properties of human skin. Correlations were obtained between parameters from the measurements and the values evaluated by experts. The dynamic properties of the cheek skins of a panel of 86 people, aged from 20 to 75 years, were measured. A remarkable reduction in elasticity was observed in older people and the lack of sebum was analysed. From these results the metabolism in the skin surface and the muscles of the cheeks were analysed. The effects of skin care products were then confirmed by measuring cheeks before and after continual use of facial treatment systems for a month. Significant recovery effects were observed in a less soft-skinned group and a less elastic-skinned group over 30 years of age. These experiments suggest a protecting effect of facial treatments and skin care products
