Improvement of the methods for skin mechanical properties evaluation through correlation between different techniques and factor analysis

Abstract

A simpler and faster methodology for the complete assessment of elasticity and firmness of human skin is possible, in alternative to elaborate and time consuming methods, involving several equipments and parameters. The simpler methodology does not reduce the information obtained about the skin properties.

Use of SkinFibrometer® to measure skin elasticity and its correlation with Cutometer® and DUB® Skinscanner

“…This provokes the skin to lose its mechanical properties, and elasticity gradually decreases . For this reason, skin elasticity is an important indicator of skin aging in basic skin research and cosmetology, and measurements of skin biomechanical properties using various techniques and their correlations have been reported in previous studies . In this study, we aimed to evaluate skin biomechanical properties using the recently developed SkinFibrometer ® device, and compared its performance with the widely used Cutometer ® device and with skin echogenicity measured by the DUB ® Skinscanner.…”

“…The skin is the largest organ of the body and represents viscoelastic properties, being composed of elastic (collagen and elastin fibers) and viscous (tissue water and ground substance) components . Protein fibers form a network to provide rigidity and elasticity . Skin viscoelasticity is affected by quantity and quality of composition of these components, and decreases as skin aging occurs …”

Forearm skin aging: characterization by instrumental measurements

“… Visioscan VC 98 (Courage‐Khazaka, Germany) for skin surface (profilometry) using the SELS system represented by four parameters: Smoothness (SESM); Roughness (SER); Scaliness (SESC); and Wrinkles (SEW) . Cutometer (Courage‐Khazaka, Germany) for viscoelastic properties of the skin; the measurement was made through the vertical deformation of the skin. The following parameters were used: R2 and R7 . Corneometer (Courage‐Khazaka, Germany) to analyse the water content of the stratum corneum through capacitance method . DermaScan‐C (Cortex Technology, Denmark) which is a two‐dimensional ultrasound (US) of high resolution or frequency (above 20 MHz), for analysis of the dermis morphology and quantitative parameters, as like dermal thickness and echogenicity . …”

Nonablative radiofrequency treatment for the skin in the eye area – clinical and cutometrical analysis

“…The stratum corneum plays an important role thanks to its water, keratin, lipids, and hydrosoluble substances. A network of protein fibers makes the dermis rigid and elastic . The improvement of tension and density of the skin result from contraction (constringency) of the “old” collagen and stimulation of fibroblasts to produce new fibers.…”
