Your response has prompted me to ask if anyone knows whether a barrier ring is necessary for skin health. We have had so many problems with leakage. My husband’s stoma is irregular in shape and slightly recessed. What has finally worked is a convex wafer and no barrier ring. We have begun to use the “Y” shaped barrier strips around the outside edges as well as the elastic belt and the pouch is good for three or four days. Now my concern is the irritated skin. I’m sure that if he gets even one lesion it will be difficult to heal.
