I'd hazard a guess that I have the most sensitive facial skin anyone could ever have; shaving has always been a problem when I don't have a few days growth in between. I've tried multiple shaving routines, products and razors and nothing has worked to prevent irritation entirely. I won't go into all the products and razors I've tried. I have finally stumbled upon a solution and surprisingly it is cheaper than most of the things I've tried. I got Proraso shaving soap and The Real Shaving Co. shave oil. I use the oil and apply the shaving soap with a brush. I'm now able to shave back to back days without irritation. I use a Mach 3 and replace the blade every 3-4 shaves. This may seem pretty silly but unless you have really sensitive skin you don't know what its like to deal with a face that feels like it's on fire for the whole day. Just to give you an example, I got a straight razor shave from a guy in Toronto who is lauded in many magazine and newspaper reviews as the best. He said in 30 some years he's never nicked anyone... He nicked me. (I didn't have the heart to tell him, LOL).
