I have seen so many bad reviews and honestly I'm shocked. I've used curology for years and went on a 6 months break due to finances and ended up signing back up but to agency this time. I've been using their products for about a week and I'm already super happy with the results. A little bit of dryness is normal the first few days to a week while your skin adjust. I had very little of that but I also use Hyaluronic acid with it and a good moisturizer to help. My skin feels and looks amazing. I think the bad reviews stem from people using the tretinoin that have never uses it before or they have super sensitive skin. It works great for me and many others. One thing to keep in mind is to make sure after you purchase your free trial go to your dashboard and make sure you only click the stuff you want sent to you or else they will send you everything and the charge is quit steep. I only use the formula. I use my own moisturizer and other skincare I like. If you are new to tretinoin make sure you only use it every other day or every 2 days until your skin adjust. Using it everyday will of course cause issues. It's a strong antibiotics aging active but an essential one imo. Love the product and always super happy with the results.
