Well... Plasters keep dirt and bad stuff out of it and to stop blood going everywhere. But cuts mostly need oxygen to heal. Plasters do give cuts scabs after a while. I normally put a plaster on for about a day and take the plaster off to let the oxygen get to it. Giving it air makes it heal quicker. It really depends on the size of cut.
