This worked pretty nicely. For the price, it may or may not be worthwhile. Didn't have any negative side effects, wasn't very drying, did seem reduce pimples/clogged pores. Doesn't leave any weird residue on skin. I only purchased it once. Have been using products from Skoah since then which are about the same price and equally effective but last much, much longer. If I hadn't found Skoah I would probably have repurchased the Help Me. It's a good product. It's not a cure-all but it really does help.
