As I said before I will get irritation with whatever I shave with if I do a third pass. What I've discovered since I am only doing the one pass now is that my face feels better than it did when I was doing two. Not that two made it feel bad .... but there were days where I felt like I ought to skip a day but I never would because I didn't want to miss the shave. Now I never have that feeling that skipping a day might be good. The one pass + touch up is a lot easier on me.
