What's Your Favorite Ingredient Complex for Acne?

I like the combination of benzil peroxide and lypo hydrox acid. I just love the combination for acne. The main humetant used in that product is glycerine. Is just such a simple product, but it is super effective for acne,. So that's combination of benzel peroxide and Lypohydrox acid. But lypohydroxic acid is only specific to laureal. That's something that i find to be quite a fascinating combination of ingredients for acne.
