As @Dave in KY said, I often deal with post-shave irritation. I have sensitive skin and eczema, so off to a good start there. But, it also feels like my skin has become more sensitive since starting Keto and losing a bunch of weight. We just have to deal with things as they come and try to make each shave better than the last. My shaves right now are much better than they were 3-4 months ago. I have had to rethink my entire approach to shaving. @BarberDave has really helped me with that.
One thing that I think you really need to do, if you aren't right now, is properly wash your face before shaving (either in the shower or at the sink right before shaving). Use a decent bar soap with good glycerin content. Something like the bar soaps from Stirling would work great. (I use this as my shower soap and face soap: CeraVe Hydrating Cleanser Bar) That should help prep your skin and beard for shaving. Once you have done that, proceed to your pre-shave step.
Keep trying. You will find things that work. Everyone has to figure out what works best for them.
