Hydrocolloid wound dressing is a wafer type of dressing that contains gel-forming agents in an adhesive compound laminated onto a flexible, water-resistant outer layer. This transparent hydrocolloid dressing is one of types of medical dressings designed for a wide range of lightly to moderate exuding wounds, such as pressure ulcers (stage I and II), leg venous ulcers, first and second-degree burns, skin grafts and donor sites, post-operative and traumatic wounds. The hydrocolloid bandages for scars also can be used on cavity wounds when used as a secondary dressing.
