do raw potatoes help with facial scars?

i heard that if you cut a thin slice of raw potatoes, and rub it for ten to fifteen minutes on the facial scar, then let the juice from the potatoe dry, that the scar will dissapear in about two weeks. is this true. because if it is, i will try it.

yep potatoes work on scars
or you could try using lemon ,cucumber, pure aloe vera and tomatoes
