Curology worked great for me for the first two months. I purchased a bottle in August of this year and it worked well. However I did notice that the bottle ran out. Maybe I was applying too much but when applying half a squirt to each area of my face I quickly ran out. The problem was in November. My skin before Curology was ok. I had consistent acne but nothing so bad I couldn’t hide it, but overall I had smooth skin. In November, I had one of THE WORST breakouts that covered the entirety of my cheeks. In fact, when writing this review in December, I am still reeling from the aftermath. My cheeks are inflamed, and I have the worst acne on my cheeks that I have ever had. The only reason I give two stars, in all honesty it should be one, is the cleanser and moisturizer. Both are amazing.
