I thought I was getting the hang of shaving with my new DE razor. Three great shaves with none of those annoying little white-head bumps that crop up between the lower lip and chin after a bad shave. One possible explanation might be that the blade was dull. I was trying to stretch a Wal-mart Persona into it's 4th shave. (I have some better blades on order) Do you think it was a dull blade? or do I still need to improve on my technique? And lastly, what are those little white-head bumps anyway? Does anyone else get them?
