It has long been acknowledged that hydration affects the biomechanical properties of the skin. However, this relationship although widely accepted, has not been entirely demonstrated. The new testing equipment CutiScan® CS 100 , recently introduced into the market, corresponds to a new approach on measurement of anisotropy and viscoelasticity, combining mechanical force with imaging in a unique way. This study aims to study the influence of hydration on the biomechanical properties of skin, as well as to observe the discriminative capacity of the CutiScan® CS 100 when compared with more conventional bioengineering equipment. To achieve this aim, a sample of 12 healthy volunteers, male and female, ages between 18 and 25 years old (22.8 ± 1.4) was selected. The study was entirely conducted in the volar forearm, where an occlusive dressing with water and glycerin was applied for 24 hours. The biomechanical properties of skin were measured, both prior and after the occlusion, with the Reviscometer® RVM 600, Cutometer® MPA 580 and CutiScan® CS 100 (Courage-Khazaka Electronics GmbH) devices. Results suggest there is an association between hydration and the biomechanical properties of skin. However, this relationship is based in the technology employed and, in our experience, must be further investigated.
Há muito que se sugere que a hidratação afeta as propriedades biomecânicas da pele in vivo. No entanto, apesar de aceite, esta relação não foi ainda claramente demonstrada com a tecnologia de que dispomos. Recentemente foi introduzido no mercado o Cutiscan® CS 100, utilizando uma nova abordagem de medição da anisotropia e viscoelasticidade, combinando força mecânica e imagem de uma forma única. Este estudo teve como objetivo estudar a influência da hidratação nas propriedades biomecânicas da pele, bem como observar a capacidade discriminativa deste novo sistema, face a outros equipamentos de utilização mais convencional. Foi selecionada uma amostra de 12 voluntários, saudáveis, de ambos os sexos, com idades compreendidas entre os 18 e os 25 anos (22,8 ± 1,4 anos). O estudo foi inteiramente conduzido no antebraço ventral, onde foi aplicado um penso oclusivo com água e glicerina durante 24h. As propriedades biomecânicas da pele foram medidas, antes e após a oclusão, com os aparelhos Reviscometer® RVM 600, Cutometer® MPA 580 e CutiScan® CS 100 (Courage-Khazaka Electronics GmbH) Os resultados obtidos contribuem para admitir a existência de relação entre a hidratação e as propriedades biomecânicas da pele in vivo, embora essa relação dependa directamente da tecnologia utilizada na medição e que, da nossa experiência, precisa de ser melhor compreendida.
