To take a bandage off with out it hurting pour water on the bandage while s-l-o-w-l-y peeling it off. About three centimeters at a time. ( if the body part that the bandage is on is small (like a finger or a toe) put it under the sink to make it easier) Hope it helps!
by soaking it in water until your skin get all pruny. However, it is not the most hygienic way to get it off. The best thing to do is just yank it. It may still hurt, but it will hurt for a shorter amount of time.
