Alginate dressings are derived from seaweed and are highly absorbent, capable of absorbing large amounts of wound exudate. This promotes a moist wound environment while preventing maceration of surrounding skin. Their ability to form a gel upon contact with wound fluid helps maintain optimal moisture balance, facilitating effective wound healing. Additionally, alginate dressings are suitable for wounds with moderate to heavy exudate, making them ideal for surgical and chronic wounds with significant drainage.
