are a type of wound care product designed to promote healing in a moist environment while providing a protective seal around the wound. Hydrocolloid dressings are composed of gel-forming agents, such as gelatin or carboxymethylcellulose, which absorb wound exudate (fluid) and form a gel-like substance. This gel helps to maintain a moist environment conducive to healing and facilitates autolytic debridement, where the body’s own enzymes break down dead tissue.

The border is made of an adhesive material that sticks to the surrounding skin which helps to protect the wound from external contaminants and friction, reducing the risk of infection and promoting comfort during wear.

Hydrocolloid dressings with borders are particularly suitable for low to moderately exuding wounds, such as pressure ulcers, minor burns and superficial wounds.
