If you've ever gotten any on your skin you know the clear adhesive drys fast and stays put. That keeps air and dirt out of the wound and that helps small skin cracks or small cuts, like a paper cut, heal. Eventually the glue wears off.
It's thought that the chemical cyanoacrylate in the glue not only stops bleeding quickly but also lead to less scarring. Although, using super glue might work in a pinch, experts say it can irritate the skin, and should never be used on deep wounds.
For a safer wound-healing glue consider Dermabond. This anti-bacterial form of the substance 2-octyl-cyanoacrylate is approved by the FDA (Food and Drug Administration) for skin wound closure.
You can also use a semipermeable dressing (Tegaderm, Bioclusive or Second Skin, or New Skin for instance) to cover the wound and attach the dressing to dry healthy skin with adhesive tape. The dressing should be changed every few days. Keep the wound moist until it has healed. A moist environment promotes healing, improves tissue formation and protects the area from infection.
