Well you didn't say if it was your third shave with just the razor or third shave period so I'll assume the latter and if that the case I would say the fact you haven't sliced your face up at this point puts you ahead of the game. If after a month of shaves you still have problems then we can talk but until then its probably just a matter of experience and technique. If you are more experienced then its easier. Either you dulled the edge stopping or your using an improper angle or too much pressure.
