When I was in medical school on my dermatology rotation, we joked that all skin treatments boil down to three decrees: If it’s wet, dry it. If it’s dry, wet it. And if in doubt, use steroids.

Skin is our first line of defense against disease. Bacteria, viruses, parasites – dangers lurk everywhere. But our epidermis (the outer layer of our skin) blocks them almost always. When people have inflamed skin, the epidermis becomes disrupted and infectious particles can enter their body.

It is designed to be sprayed into wounds where it expands and adheres to tissues in order to slow or stop bleeding. The company is also working on a novel chitosan-based wound dressing which uses “nano-hooks” in order to better adhere to bleeding tissues. Read more »
