Mario Badescu's Drying Cream (and Mask) are lifesavers.  This is a great basic acne cream that works fast.  It can be worn under makeup and has a bit of a concealing factor too.

This is a sulfur based drying cream.  If you have problems finding products that work on your skin, try this one.  Salicylic acid products do not work for me.  They are too irritating. 

The sulfur stinks a bit, but it really is not too bad and goes away pretty fast.  

It works on whiteheads the best, but is good for cystic acne and blackheads as well.

The silver powder is better for blackheads and buffering lotion...
