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… 
Skin ageing: changes of physical properties of human skin in vivo
TLDR
These parameters, which are used in mechanics to define the intrinsic physical characteristics of materials, were measured for the first time on volar forearm skin of 206 male and female subjects, aged between 6 months and 90 years.
Quantitative morphology of dermal elastic fibers system of the human face during aging.
TLDR
A color image analyzer indicated distribution of elastic, oxytalan, and muscle fibers in human face skin, and face movement might be an important aspect to maintaining the EF content of human faceskin.
Useful parameters for the motion analysis of facial skin care in Japanese women
TLDR
ApEn and Rest γ are useful parameters for evaluating quality of hand motions during FSC, and it is suggested that the behavior of FSC influences the autonomic nerve system.
Facial skin rejuvenation
TLDR
The physician has an important role in understanding which treatment options are appropriate for mild, moderate, and severe photoaging, and in educating patients on the risks and benefits of each.
Objective analysis of the effectiveness of facial massage using breakthrough computed tomographic technology: A preliminary pilot study
TLDR
This preliminary pilot study aimed to verify the effectiveness of facial massages by using breakthrough computed tomographic technology to quantify objective evaluations of massage‐induced changes.
Epidermal growth factor improves the migration and contractility of aged fibroblasts cultured on 3D collagen matrices.
TLDR
The results suggest that rhEGF is a potential renewal agent that acts to improve the migration and contraction of aged fibroblasts more efficiently than young fibro Blasts under 3D culture conditions; thus, EGF may have valuable regenerative effects on aged skin.
Extract of the mycelium of T. matsutake inhibits elastase activity and TPA-induced MMP-1 expression in human fibroblasts.
TLDR
The data suggest that the extract of the mycelium of T. matsutake may prove to be an effective biomaterial for anti-wrinkle treatment, as it can obstruct the degradation of the dermal ECM.
Rejuvenating facial massage – a bane or boon?
Background Facial massage is an extremely popular form of beauty treatment and is thought to rejuvenate the skin. We decided to study the benefits and untoward effects of this form of facial beauty

Measurements of Skin Elasticity and Slip
TLDR
The “Skin Age Parameter” which indicates recovering power showed a good correlation with the age and skin rheograms made before and after the use of a facial mask also showed interesting differences under initial pressure.
The Development and Application of a Robot Type Measuring Device Equipped with a Tactile Function
TLDR
The potential value of a palpation robot is suggested following the successful realization of the analysis of the stress changes and dynamic properties of human skin through an obiective process.
in vivo measurement of skin visco-elasticity
TLDR
A method is described that can measure the mechanical properties of the skin using decade filters and computer with developed noise suppressing logics, and is sensitive enough to detect the difference in visco-elasticity between sites of the body, and the differences between before and after application of lotion.
