Retinoids are one of the best treatments if scrubs and standard acne approaches have not worked.
Antibiotics are a possibility, but for many reasons I find this to be an inferior treatment.
I am assuming you have tried benzoyl peroxide along with a daily scrub, and that this has not worked.
This requires a prescription however.
