An ostomy faceplate and its method of application are disclosed in which the faceplate comprises an annular adhesive wafer (15) of soft, moisture-absorbent, memory- free, essentially non-elastic and finger-mo ldable adhesive skin barrier material, the wafers distal surface (17) having an outer zone terminating at the outer periphery of the wafer and an inner zone extending inwardly from the inner limits of the outer zone to a stoma-receiving opening at the inner periphery of the wafer. The faceplate also includes a flexible backing layer covering the outer zone and a removable cover member (25) having a smooth surface releasably covering the proximal bodyside surface of the wafer. The distal surface of the inner zone has undulations defined by a plurality of concentric ridges (28) and valleys (29) with the ridges progressively diminishing in thickness, when measured by the distance between the distal and proximal surfaces at each ridge, as the series progresses inwardly from the maximum thickness of the wafer towards the stoma-receiving opening. The method of application includes both a preliminary molding step and a secondary molding step.Linvention concerne une plaque frontale de stomie et son procédé dapplication, la plaque frontale comportant une rondelle adhésive annulaire (15) constituée dun matériau adhésif de barrière cutanée, ledit matériau étant mou, hygroscopique, sans mémoire, essentiellement non élastique et façonnable avec les doigts, la surface distale (17) de la rondelle comprenant une zone extérieure se terminant à la périphérie extérieure de la rondelle et une zone intérieure sétendant vers lintérieur à partir des limites intérieures de la zone extérieure jusquà une ouverture recevant la stomie à la périphérie intérieure de la rondelle. La plaque frontale comprend également une couche-support souple recouvrant la zone extérieure et un élément amovible (25) de couverture présentant une surface lisse recouvrant de façon détachable la surface proximal
