Which brush are you currently using?
Without wanting to understate the previous messages, an adittional possible cause may be the wrong (for your skin) brush that you are using. I mean that a more gentle brush (synthetic knot maybe?) may help you reduce the irritations you are having.
+1 for Body Shop Maca Root.
Although I have not yet used the Baume.be cream, so that I could express a personal opinion, it also has quite a lot of good reviews from shavers with sensitive skin.
