The Allevyn Wound Dressing provides a barrier between your skin and your surrounding environment. Bacteria, among other infectants, will not be able to permeate the dressing. However, because this dressing is semi-permeable, it does allow oxygen and water vapor to pass through it. In effect, this will hasten your healing time.
Featuring highly pliable, self-adhering material, the dressing will conform and tightly hug the contours of your body. This dressing will even securely stay in place over bony areas. Although this product is an adhesive, it will not adhere to your wound.
Bandage does not seem to adhere to skin as well as regular Allevyn. I have a wound on buttox and any shifting or other movement makes the bandage unravel. On the any other body part, it might be a different story.
