Close shave and razor burn fix?

Hello! Apologizes if this doesn’t belong here.

I shave my face every other day, and even on days when I have a fresh shave, I never feel like I have a fully “clean” shave. That is, I always seem to have some shadow.

I also have razor burn that never seems to disappear. I try shaving with the grain of my hair, against it, rinsing with cold water, applying aftershave, nothing seems to work.

Do you guys have any advice? I appreciate it!
