Abstract: Disclosed is a method for applying an adhesive composition to the skin of a user and for removing the adhesive composition from the skin. The method includes the steps of providing an adhesive composition including a switchable adhesive; applying the adhesive composition to the skin; exposing the switchable adhesive to a first switch activator, thereby switching the switchable adhesive from an application state to a wear state; exposing the switchable adhesive to a second switch activator, thereby switching the switchable adhesive from the wear state to a removal state; and removing the adhesive composition from the skin of the user.

Abstract: A convex shell for use in a base plate of an ostomy appliance includes an annular ring with a through-going hole and a plurality of grooves extending transversely across the annular ring. The grooves alter the flexibility of the annular ring as a first portion of the annular ring is folded around a folding axis toward a second portion of the annular ring.
