In many places, I read that it's best to avoid any scab formation when someone gets Dermabrasion or laser treatment. When I was little, I always thought that the best way to preserve a wound was with it's own crust and wait until it fell of by it's own.
So the question is: why is now the standard in dermabrasion and laser treatments to keep the scabs from forming? Why not let the body heal by it's own? Isn't it more dangerous to keep any wound open?
