Is it acne or in growing hairs causing the acne? Try not shaving against the direction of growth, do across or with the growth. I use a wet alum block sometimes, helps with small cuts and irritation after, however it stings like fuck. One block will last you a life time unless you drop it. Also a face scrub can help the day after, however the wife has an oil based soft one that makes my skin worse, I have to use a more aggressive non oily one
