152 Evaluation of the SkinCam, a Connected Portable Camera Device, for the Analysis of Skin Microrelief

Silicone replicas and non-contact methods are effective in analysing the micrometric scale of plateaus furrows that forms skin microrelief. Yet, a major drawback is obligation to capture data research facilities. Therefore, capacities connected portable camera device, SkinCam, was evaluated analyse microrelief real-time while subjects were living their regular daily life routine. The effect moisturisers on also analysed. From RGB data, 3D depth maps constructed using shape from shading algorithms. Roughness heterogeneity (Spa) computed, profiles extracted calculate furrows/plateaus features: numbers, depth/height area, as well Ra roughness parameter profiles. inner forearm 18 (23-60 years old) evaluated. While life, they self-performed triplicate acquisitions at various times. vehicle cream containing moisturisers, either saccharide isomerate, urea or xylitylglucoside-anhydroxylitol-xylitol, studied, untreated reference. Considering 102 series, results show sound coefficients variation. We find known correlation between age evolution Eight hours after single application, all induced 1.6 2.1 folds decrease Spa. Only isomerate xylitylglucoside-anhydroxylitol-xylitol decreased (-2.4/-2.3 folds). In terms microrelief, area reduced by 1.3 1.9 active ingredients, highest being for xylitylglucoside-anhydroxylitol- xylitol. height diminished -1.5 (urea) -2.1 (xylitylglucoside-anhydroxylitol-xylitol). SkinCam enables analysis, even under nomadic conditions. It allows monitoring changes upon application.
