I have combination skin that leans toward the oily side. I use this right after cleansing as a toner before my "first treatment essence" and during the first month of using this, I didn't see much difference in my skin. However, during the second month, I noticed that my face was much less oily, I didn't break out anymore, and my whiteheads/ blackheads decreased, although they didn't disappear. Just to see how big of a difference it would make, I went without this for two weeks and by the second day, I had started breaking out with small red bumps on my face and especially in the chin area. Overall, this product definitely clears pimples, brightens complexion, and decreases sebum.
