Literally was covered in acne for about 4 months and nothing from the doctor, pharmacy or natural remedies had any impact at all in stopping it. It was so bad I went to the doctor for some other problem and the first thing he did was comment on my acne and book me an appointment with a dermatologist for accutane, but decided to have one more attempt at stopping it with some other products online that I hadn't tried as I have really bad ezcema with dry skin so the accutane would have literally destroyed me. Within 1 month, my cystic acne with at least 40+ active pimples turned into about 5 pimples, and 2 months on it literally COMPLETELY cleared. Now about 4 months in, haven't had a spot for about 2 months. can't believe how well this has worked, saved my skin from that poisonous shit that wouldn't have even worked as well, if you're struggling with acne 100% give this a go. *Note: I had / have severe eczema, had it all over my face and this surprisingly didn't have any negative impact at all, can't recommend this enough!
