What is the primary purpose of a hydrogel dressing?

The primary purpose of a hydrogel dressing is to provide moisture to the wound. Hydrogel dressings are made up of water or glycerin, giving them a high moisture content that helps maintain a moist environment, which is crucial for wound healing. A moist environment can promote cell migration and facilitate the healing process by preventing the wound from drying out and forming crusts, which can hinder healing. Moreover, these dressings are particularly beneficial for wounds with low to moderate exudate, as they can also help in pain relief and may cool the area upon application.

While other types of dressings serve different functions, such as keeping the wound dry or absorbing excess discharge, hydrogel dressings specifically prioritize hydration as a means to support and enhance healing.
