Use a mild antiseptic to help prevent infection during the 15 to 30 minutes that it takes for the skin to heal after shaving and try not to touch your face at this time, however tempting it might be.  An excellent and easy option is a splash of Witch Hazel which will tone as well as protect the skin.  If you want to smell great then try Vetyver Aftershave balm from Fragonard; but only use it on the neck.
