Hollister HolliHesive - Skin Barrier Seals is a 4" x 4" skin barrier that is gentle on the skin. Hollister HolliHesive protects the peristomal skin from irritating stomal discharge even when heat and moisture are present. This ostomy supply has adhesive on both sides of the skin barrier. Hollihesive is not made with natural rubber latex. The skin barrier can be cut to provide a custom fit around the stoma. This barrier is to be worn under an ostomy wafer to protect the skin from stomal discharge and ostomy wafer adhesive.
