Concave is the first product specifically designed to fit bulges, hernias and curves. The curved star-shaped skin shield fits snugly around bulges, hernias and curves. The star-shaped petals hug the body without creasing or bending. The ring stabilizes the central part, in order to offer the stoma the necessary support, then it acts as a guide to know where to exert the pressure during the adjustment. Finally, the stretch adhesive and the adjustable zones follow the movements of the body. All these advantages taken together ensure better contact between the adhesive and the skin.
