[en] Tensile properties of skin determine some important physical attributes of skin. They may be conveniently assessed using recent technologies. The aim of the study was to compare ex vivo the tensile properties of normal looking skin and striae distensae. The Cutometer was used with 2 and 4 mm diameter probes. Skin distensibility values were dependent on the suction force and area of the skin tested. Conversely, tensile ratios yielding elasticity parameters were not affected by the same variables. Although tensile properties of excised normal skin resembled those previously reported in vivo, striae distensae showed markedly different properties in vivo and ex vivo. The ex vivo and in vivo evaluations of the tensile properties and functions of skin are complementary particularly when the connective tissue is abnormal.
