It's very effective for acne and I've noticed that it'll get rid of acne in a much smaller space of time. It doesn't have a pleasant smell, but that fades after application. Sometimes I just use it as a spot treatment because it stings a little bit over open spots or sensitive areas of my face. If you decide to use this product, I would only recommend using it a few times a week (not as an every day product) and don't forget to use a good moisturizer!
