Jovan - I had pretty bad razor burn when I shaved too often (like, more than 3 times a week). I was using a Mach 3, sensitive skin gel, and some face moisturizer
I switched to a SensorExcel - it's only got 2 blades, so it's not as irritating, and cartridges are much cheaper. AND I haven't even noticed it cutting any worse, once I learned to stop pressing it into my skin, and instead lightly drag it.
That one switch took care of most of the problem. This summer I started using this Sharps Barber Brigade aftershave gel I got from Target for about $7 (it was by the specialty-type skin-care products, away from other shaving stuff). I think Sharps' regular line is pretty high end but the Target line seems to do fine. Now I hardly get razor burn, even shaving every day, except sometimes on the upper part of my chin.
yeah, I'm sure it would be better if i used a badger brush and all that, but it's fine now...
