Honestly, I had a lot more expectations from this product due to a lot of hype. In 30 days, I did not see much change in my skin. Though, my skin does not have a lot of acne, only here and there. After using this product, I noticed my skin had acne that popped up here and there. Perhaps it is my skin reacting to the product? Regardless, it did not improve the acne on my face. However, I did notice that my face was brighter. I am pretty sure it was due to the chemical exfoliation, since this product contains AHA and BHA. I think that this toner performs like any other AHA/BHA toners. If you have more troubled skin, you probably will see more results. Though, I doubt the 30-day results. I think you will start seeing noticeable results after about 60 days.
