What type of wound is hydrogel typically used for?

Hydrogel dressings are commonly used for dry, ischemic ulcers because they are designed to provide moisture to the wound environment, promoting healing. Ischemic ulcers often lack adequate blood flow, leading to dryness and difficulties in the natural healing process. Hydrogel helps to rehydrate the necrotic tissue, making it easier for new tissue to form and for the wound to heal.

Additionally, hydrogel can also serve as a barrier to external contaminants, protecting the wound from infection while maintaining a moist environment. This moisture helps in alleviating pain and discomfort often associated with dry, ischemic wounds, which is another reason why hydrogel is particularly useful in this context.
