Gorilla Glue is toxic to your skin and can burn your skin if left on your skin too long.
But if you get Gorilla Glue on your skin for just a few minutes and then remove the Gorilla Glue as soon as you can then the glue should do no harm to your skin.
If you do get Gorilla Glue on your skin you can use acetone nail polish remover to remove the gorilla glue from your skin.
Then you just use regular soap to wash your skin to remove the nail polish remover and gorilla glue residue from your skin.
I always try to wear some rubber gloves when using adhesives including gorilla glue to prevent it from getting onto my skin.
But sometimes I forget to put on the gloves and then use acetone nail polish remover to easily remove any adhesives or gorilla glue on my skin and other surfaces.
