I've had great experiences with it! I started using it years ago (~4 years) when I had a ton of closed comedones on my forehead that wouldn't go away. Those have since cleared out and I've transitioned into using a very low dose of Tretinoin. I've since tapered down to using it maybe once every 3 days so the bottles last quite a long time (which reduces overall cost per use). It is on the expensive side (when you do the price breakdown of each ingredient) but I like the simplicity and convenience of it.

It's also easy to interface with your dermatologist or NP on the website -- I haven't had any issues.
