I have to say, in addition to how great the product works, I am really liking the customer service. If I forget to halt a delivery (I switch between Curology and my Korean nighttime skincare routine, so don't need a delivery every month) I can always email customer service to skip a month, which I do every now and then. But every time, they have, no questions asked, made sure my delivery was halted, and credited me back my payment. I also like how I can email the doctor and discuss my skincare needs. I would like my next curology formula to be more for dark spots, as my acne has cleared up, but the dark spots linger! Also, the product works! My acne has cleared up, something that had not happened since my twenties!
