I have been using this product for about 6 months, I primarily use this when I am having a breakout, not to prevent them. I dab a little bit directly on the problem area after I have washed my face, and within a day the breakout is usually less noticeable. On days when I need to use this product, and I must wear make up, I still use my regular face cream after applying the product, because it can be slightly drying if you over use it, it does say this right on the label, so I know this may happen beforehand. Overall this product does work, just watch for drying and it will work for you. I do not have sever acne, only an occasional break out, so I cannot say whether or not it would work for a severe case of acne.This is especially helpful when I get a that time of the month breakout.
