I have had moderate to occasional acne throughout my twenties. I tried Curology out for 6 months to give it a shot. After the first month, my skin got worse, and I was advised that I was simply experiencing this "purging" stage. However, my skin continued to get progressively worse every month instead of better. I wish I had just gone back to a proper dermatologist - over the counter "prescriptions" just aren't going to cut it with someone with moderate to severe cystic acne like myself. My face has suffered severe acne scarring over the last few months that I'm not sure it would have had I just gone to a proper dermatologist in the first place. I grant that the cleanser and moisturizer are very easy on my sensitive skin, but potentially not very effective for my situation.
