Everyone has different skin types but coming from an old guy who has always had slightly sensitive skin, I offer the following advice.
Always shave after you shower. Shower for at least 10 minutes in comfortably warm water or as warm as you can handle it. Then shave immediately after.
There'* a lot of truth in the old saying SSS. Sh.it, shower and shave.
The best after shave I have found...and I have tried them all...is Old Spice after shave. Forget the Cologne, it'* too strong Ya ya I know what you're thinking, but heh, it works. It helps after applied to rinse off your face to remove most of the very strong odour. The burning sensation cools your skin and prevents razor burn. Ya gotta try it before you knock it.
Women love the smell as long as it'* not over powering.
