Instead of plastic rings, a foam adhesive securely couples the pouch to the skin barrier's clear plastic Landing Zone." The result is a low profile, flexible, secure system, with the convenience of a one piece and the versitility of a two-piece. Esteem synergy skin barriers feature Stomahesive or Durahesive technologies and are designed to be gentle yet durable to protect sensitive peristomal skin.
