Try a loofa or "buff puff" promptly after shaving to exfoliate the skin. It's super sensitive, so don't use much pressure, but it seems to elieviate any rash or bumps left by the razor. Then, I recommend some serious moisturizer. Anything good enough for your face should be perfect for your lips!

Good luck!

And like Tigress said...use a FRESH razor~!

PS. My girlfriend likes the brazillian wax. She says after 3 or 4 times, it doesn't really hurt anymore! Yeah...I don't believe her either.
