Accutane is kinda bad in my opinion. I took it for a while when I was younger and got pretty depressed and stuff, which I know is sometimes a side effect. Plus it didn't eliminate it forever, just when I was on the stuff.
Simply just use astringent. Depending on how sensitive your skin is, pick your astringent. I have very sensitive skin so I just use pure Witch Hazel. A lot of other brands of astringent have witch hazel in them, but others have alcohol which are a lot more harsh on your skin. Just put some astringent on a cotton pad and wipe your face down every night before bed. I had TONS of problems with acne for a loonnnnggg time, and this was finally the solution, as simple as it was. Don't overdue it or your face will be a disaster.
