Hydrocolloidal dressing is commonly known as artificial skin; easy to tear, has non-adhesion to the wound, will not cause secondary damage, and reduce pain. Hydrocolloid dressings are wafers, powders, or pastes of gelatin, pectin, and carboxymethyl-cellulose. They provide a moist environment favourable for wound healing and a barrier against exogenous bacteria.
Compared to wounds treated with 1% silver sulfadiazine, wounds treated with hydrocolloid occlusive dressings demonstrate faster healing, reduced pain, and require fewer dressing changes, resulting in lower overall care costs. Hydrocolloid dressings are particularly effective for small-area partial-thickness burns, especially during the final stage of spontaneous healing in minor burns. These dressings can absorb limited wound exudate; excess fluid may leak out, known as 'strike-through.' Due to their quick absorption, these dressings are best suited for rehydrating dry necrotic tissues and wounds with dry yellow slough.
