I would've rated higher (maybe a 2 since ik it worked for some people) but I thought the 4.3 rating was too generous haha If you're looking for an easy place to get tretinoin I would recommend, but there are other (cheaper) places to get tretinoin without having to go to the dermatologist. I personally didnt see a difference (if anything it got worse) after using it for a year. I've been on tretinoin before and it worked wonders so I'm still confused why curology didn't work :// Could be because they're lacking in their inactive ingredients??? Like I haven't seen centella asiatica or niacinamide even after asking for it (which I used after curology and they seem to be helping more than curology tbh) I would often ask questions to my assigned skin expert but it did feel like they would share basic info unless I asked extremely specific questions to me and even then it felt like they were just trying to sell more curology products to me Lastly, as other reviews said, the customer service is TERRIBLE!!!!! One of the main reasons I stopped (beside it not working after a year haha)
