Several years ago I needed this product after a fall resulting in a laceration. It worked well. Now I suffer from lower leg skins ulcers caused by diabetes. These dressings seem to hasten the healing process.
They are placed directly over the wound, and have an adhesive perimeter that holds them in place. By the way, the dressing itself also seems to contain an adhesive. The dressing keeps the wound tightly sealed from air and water. The chemical inside some how works well to help the wound heal more quickly. It can remain on the skin for up to a week. As healing occurs, the dressing seems to swell and turn white immediately over the would. Great product.
