Skin indentation firmness and tissue dielectric constant assessed in face, neck, and arm skin of young healthy women

Abstract

The near-zero correlation may be due to low skin interstitial hydraulic resistance to mobile water movement in healthy young skin. If true, then conditions in which dermal hydraulic conductance is reduced as in lymphedematous, diabetic, or aged skin are more likely show the hypothesized relationship. Our findings provide normalized reference values and suggest that such persons are an important population to study to test for a possible skin water-indentation force relationship and its utilization for early diagnosis.

Accuracy and reliability of a hand‐held in vivo skin indentation device to assess skin elasticity

“…The skin stiffness of healthy female volunteers was found to decrease with ageing. This finding is in line with several previous studies conducted with indentation principle , Cutometer and various other techniques . The age‐related decrease of skin stiffness is caused by the degeneration of the skin elastin and collagen network and decrease of skin thickness .…”

“…Mayrovitz et al . also noticed that in facial skin the 0.3 mm indenter data correlated well with the 1.3 mm indenter results. However, the 1.3 mm indenter might be too long to assess elasticity of a thin skin, but for the determination of subcutaneous firmness, a longer indenter of 1.3 mm is feasible.…”

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

“…The authors noted that the SkinFibrometer ® had a good to excellent reliability compared with other devices, and is appropriate for assessing tissue compressibility. Another previous study applied the SkinFibrometer ® to measure skin firmness of face and body sites, and to correlate these measurements with skin hydration . However, they found no significant correlation between skin softness as measured by indentation force and tissue dielectric constant values representing skin water content.…”

“…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.…”

Assessment of local tissue water in the arms and trunk of breast cancer survivors with and without upper extremity lymphoedema

“…To date, most of the studies that used TDC have assessed healthy women (Mayrovitz, Corbitt, et al 2017; Mayrovitz, Fasen, et al 2017) and upper extremity swelling in women with and without breast cancer-related LE (Mayrovitz et al, 2015a,b; Mayrovitz et al, 2014; Mayrovitz et al, 2008a,b; Lahtinen et al, 2015; Bakar et al, 2018). Findings from these studies suggest that TDC can reliably detect inter-limb differences in LTW in women at risk for and with LE (Mayrovitz et al 2015a; Mayrovitz et al, 2014; Bakar et al, 2018; Lahtinen et al, 2015).…”
