I am a long time wet shaver but new to DE shaving and getting horrible results. My old shaving system was a Mach 3 blade, Anthony Logistics shave gel, Anthony Logistics balm, shave in the shower. I used to get really good results with this, very close shave, little to no irritation. You might ask why I switched and the reason is I always wanted to try DE shaving, maybe even straight edge at some point. I also am intrigued by brushes, diff creams and soaps and just the "old fashion" way of shaving. So my first shave was 4 days ago and it was with a Merkur HD, Derby blade (out of my sample pack), L'Occitane Cade soap, L'Occitane Cade ASB, Pennworks silvertip brush. I showered before the shave and decided to shave after the shower at the sink to get a better view in the bathroom mirror. I have watched Mantic's videos on Youtube so I had an idea as what to do. The lather was pretty good for my first time and I did 3 passes. Two WTG and 1 AGT. When I was done I had a really bad burning sensation all over my face even after a cold water splash and applying the balm I also had a lot of red bumps on my cheeks and throat which is very rare for me. The burn lasted for a few hours and was very uncomfortable. I went to splash some cold water on after awhile just to try and soothe it. Today I decided to try again. Same products as the first time but I shaved in the shower with my fog free mirror. I made a very conscience effort to use NO PRESSURE. I did only two passes, 1 WTG and 1 XTG. When I was done I had little to no burning sensation, thank god, but I did have a few red bumps on my throat area. The closeness of the shave is horrible. I mean I have spots that look like I didn't even touch it. I would have gone for another pass but decided to quit while I am ahead and try to get it next time. I am really at odds here over what is the issue other than I am new to this which could be the biggest factor. Could it be the soap I am using, the blade, all of it? I am almost tempted to try the Mach 3 with the soap to see if that is the problem. I also have a tube of C.O. Bigelow that I could try and some Tabac I received but unfortunately it arrived with a cracked bowl. It is just hard going from smooth comfortable shaves with the Mach 3 to bad razor burn and patches of hair left on my face. What is the advantage of the DE razor?
