What is the best acne medication that a dermatologist would recommend?

That depends...: ...On what kind of acne you have, what skin type (oily or dry), how old you are, your gender, what medicines you take, and a host of other factors. The point is that there is no one "best" acne treatment, only the best one for your particular circumstances. And your dermatologist needs to examine you and ask a lot of questions to determine what that treatment is.

Depends: The best medication is determined by the type of acne. In general, good over the counter medications are those containing salicylic acid or benzoyl peroxide. For a good prescription regimen, see your local dermatologist. Good luck!
