Is this really true?

I don't know about that, but I have been using CA glue to seal up cuts for years. I used it when I raced mountain bikes, as it was good for sealing tires and sealing boo-boos.

My wife actually got cut about a year ago. Could used a couple of stitches. I washed and prepped the wound and sealed it up with some CA. Looks better than it would have coming from the hospital. No scar or anything.

Just be sure to wash the area first, and use the CA within 1-2 hours. Press the skin together, and place the CA on top. It will bond the skin to itself and form a protective barrier that is better than a Band-Aid. Its also waterproof. If it starts to come off, just reapply and your good to go.
