A truly customizable skin care plan. I love that it was based on my skin care concerns, and I had someone who was able to see photos of my skin and recommend a plan. And the follow up with me to make sure everything is working well. Always having someone to answer my questions is wonderful. The only con I have is the bottles the formula comes in is terrible. The first month trial they both broke within the first week. The second month full size was better, but still had to pump it a few times to get product. But overall a wonderful subscription that I plan on keeping.
