Potentially the easiest and cheapest option, "Clay masks help draw out impurities such as dirt and oil at the surface level of the skin which helps with acne breakouts. It will help to dry up the acne," says Dr. Bank. You can usually find a large tube (meant for your entire face) at the drugstore, and using it as a spot treatment will make it last forever. Just look for a mask with kaolin or bentonite clay as the primary ingredient.
Drugs: Some medications may cause or worsen acne, such as those containing iodides, bromides, or oral or injected steroids (either the medically prescribed prednisone [Deltasone, Orasone, Prednicen-M, Liquid Pred] or the steroids that bodybuilders or athletes sometimes take). Other drugs that can cause or aggravate acne are anticonvulsant medications and lithium (Eskalith, Lithobid). Most cases of acne, however, are not drug related.
