I used Curology for over a year and saw no change in my skin. That part is whatever. I understand products don't work for everyone- even thought it is "customized" lol lol. My beef with Curology, and the reason I NEVER recommend them, is that the company clearly is only out for profit and couldn't give less cares about the health of your skin. They made it unbelievably difficult to cancel my subscription, and even after I did, I received thirst emails from them begging me to come back for three months. I had to block their emails. And there's also a reason they make it so difficult to review their products. Anyway, don't subscribe with Curology. I wasted SO much money on a product I could've picked up from the drugstore.
