“…Dermis thickness and echogenicity were determined with a 20 MHz ultrasound Dermascan C ® device (Cortex) containing a transducer focus that is used to obtain two‐dimensional transverse images, represented in the B‐mode software. The ultrasonic wave (speed of 1580 m s −1 ) is partially reflected by the skin structure, giving rise to echoes of different amplitudes .…”

Objectives In view of the lack of studies about the morphological and structural changes caused by solar radiation in young people, the aim of the present study was to evaluate the photoageing‐related changes in the skin of different age groups by biophysical and imaging techniques. Methods Forty‐four healthy female subjects were divided into two age groups: Group 1 (G1): 18–35 years old and Group 2 (G2): 40–60 years old. The skin of malar region of the face was evaluated in terms of mechanical properties, disorder in the pigmentation pattern, morphological and structural changes using the Cutometer®, Colorimeter®, Visioface® and Dermascan C® devices and reflectance confocal microscopy (Vivascope®). Results The results showed that the main changes in the skin of G1 were related to the pigmentation pattern, the papilla format and depletion of thin collagen fibres. These alterations were also observed in the skin of G2, but with more pronounced effects. Conclusion The knowledge about the skin changes caused by photoageing obtained in this study is very important for the development of dermocosmetic products for more effective treatments particularly focused on this type of skin. Finally, objective characterization of photoageing showed the importance of photoprotective habits since the first years of life in order to retard the appearance of skin changes caused by solar radiation.

“… 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 . …”

“…It is possible that the dorsal surface of the upper extremities is also exposed to similar levels of UV exposure. While exposure of skin to UV radiation promotes Vitamin D synthesis, chronic exposure causes photoage‐related degenerative changes that impact cellular, fibrous, and vascular skin structures . The cumulative effects of UV radiation on exposed skin surfaces have been shown to clinically manifest as elastotic skin changes, purpura, uneven skin pigmentation and melanoma and non‐melanoma skin lesions …”

The objective of this study was to construct a predictive model to identify aged care residents at risk of future skin tears. Extensive data about individual characteristics, skin characteristics, and skin properties were gathered from 173 participants at baseline and at 6 months. A predictive model, developed using multivariable logistic regression, identified five variables that significantly predicted the risk of skin tear at 6 months. These included: a history of skin tears in the previous 12 months (OR 3.82 [1.64-8.90], P = 0.002), purpura ≤20 mm in size (OR 3.64 [1.42-9.35], P = 0.007), a history of falls in the previous 3 months (OR 3.37 [1.54-7.41], P = 0.002), clinical manifestations of elastosis (OR 3.19 [1.38-7.38], P = 0.007), and male gender (OR 3.08 [1.22-7.77], P = 0.017). The predictive model yielded an area under the receiver operating characteristic curve of 0.854 with an 81.7% sensitivity and an 81.4% specificity. This predictive model could inform a simple but promising bedside tool for identifying older individuals at risk of skin tears.
