I have only been using these products for two weeks, but I am already very impressed with them. My skin hasn't cleared up drastically yet, but my understanding with these products is that you will see steady improvement over time, unlike many drugstore acne products that promise "overnight improvement" but do little for the health of your skin over time. I love the quality of all the products so far and though I haven't seen overnight improvement, my skin feels much healthier! I only gave it a four out of five stars because it took nearly three weeks for me to receive my products because they were backordered. However, their customer service was great and they stayed in communication with me about when my products would arrive and even gave me a discount because it took so long. So far, I'm very impressed!
