Honestly, the first week I was kind of disappointed and eventually stopped using it because it made my skin itchy and gave it a burning sensation. and a month later while I was still using the other products from the line, I decided that I would give it another try before I throw it away. And My God, I am so happy that I didn't throw it away. I guess my skin adjusted to it and I don't know how to put this in words but this treatment is a tube of miracle when it comes to fighting blackheads and acne. It literally prevents the acne from happening and lightens the previous dark spots on your face. I have been using this every day for a few months now and I can't even imagine not having it in my face care routine. I don't usually write reviews but I realized some people might have experienced it the same way that I did the first time and gave up on it so I'm here to tell you if that's the case do yourself a favor and give it another try and maybe use it less frequent until your skin is adjusted to it. You won't be disappointed.
