I don't really have a lot of cystic acne or large noticeable skin issues so honestly, I didn't see very obvious results or large differences. But, however, I have noticed my skin feeling smoother, the skin tone feeling more even, and a lack of newly developed acne after using this every day for 3 weeks. This product is a good preventative measure and overall well formulated however you have to keep using it for a good while to start seeing long-term skin benefits.
