This is the OP.

I got a medication from my dermatologist - it's an antibiotic, I think? I use Cetaphil cleanser, rinse it off, pat my face dry gently with a towel (I only use this towel for my face), and then apply the antibiotic. It's on a roller type of thing, so I just dab it lightly on the affected areas. After that I put moisturizer on it.

If you see anything wrong with this routine, please tell me. D:
