I normally use Shiseido Men Hydrating Lotion after shaving and so far it has done a pretty good job. If I get any cuts during shaving I'll use a drop of pure Tea Tree Oil on the cut.

if u constantly getting cuts, razor burn or bumps after shaving I recommend u try a better pre shave regiment. wash face wit cleanser b4 shaving n use a good shaving foam. sometimes those 3-4 blade razors r overkill if u dun have much facial hair...not to mention expensive. i use my grandfather's 40 yr old double edge razor and the shave is almost perfect. a pack of 5 razor blades cost RM 4.50.
