Dermologica overnight clearing gel is great! I read about this product on Makeupalley.com and it got rave reviews. I had been suffering from mild acne, not bad but I would constantly break out on my chin and sometimes my forehead. SO I was in search for a "miracle" product. While this hasn't performed miracles it has cleared up my skin and without leaving it dry. The active ingredient in this product is Saliyic acid, most other anti-acne products were too drying on my sensitive skin. The first night I used this I washed my face and put a thin layer of this on (don't put moisturizer on!) and I swear I could see results overnight, my whole face just looked clearer and brighter and my pores seemed much much smaller. I read somewhere that you should not put anything on over this, like a night cream or moisturizer but since this is not drying I dont see it an issue, in the morning I wash my face and then apply my moisturizer. The only thing about this product is the price. It is about $40 at the store (I ordered mine off e-bay for a cheaper price) but I must say it works great and seems to last for a while. I bought my bottle about 2 months ago and I still have over half left. You only need a dime size for the whole face and if your just spot treating you will need even less. I totally recommend this product to anyone suffering from acne with sensitive skin.
