I have a heavy beard so it is pretty much necessary for me to go ATG but I find one of the harder spots for me to get is my upper cheek. I have no idea why this is but what ends up happening is multiple passes resulting in razor burn in that area. I am inclined to think that my technique is somewhat at fault but most everywhere else I go ATG is generally a one and done with great results. I tried blade buffing the areas but over the course of the week, it produced razor burn too. I am wondering if the hair in that area grows at a slower rate and that is why I am only able to get a decent pass a day after I skip shaving.
