The dressing is non-prescription semi-permeable occlusive biosynthetic material derived from an acetobacator xylinum, a non-pathogenic bacterium found in nature.

The cellulose product is approximately .05 mm in thickness and when dry has the consistency of very thin tissue paper, but upon wetting acquires significant resistance to both sheer and tear force. Microbial cellulose acts as a scaffold covering the granulation tissue and will help to attract fibroblasts to the wound base which in turn, lay down collagen and growth factors enhancing the healing process.

Because the material acts like epidermis (semi permeable) and allows for transpiration of fluid and gases, the contact surface remains moist, TcP02, so that epithelialization occurs over the granulating tissue.
