Cost too much as the same ingredients products in the market are far cheaper. They tout a real derm doctor helping you through the journey but it's a pretty standard template they use that isn't as customized as they market. Also, there is no bi-directional communication with the derm doctor. You get only 2 messages to them every so often and you can't reply to any of the answers they give you so need to use your message credits to clarify an answer. Lastly, they cycled me on and off some prescription strength ingredients but you still pay the same subscription price. What I found is that the non-prescription ingredients didn't do anything at all to help remove dark spots (my dark spots got worse during that time) so they are basically just trying to keep you on a subscription even though they should have just stopped during the period to give your skin a rest from the strong prescription ingredients. Lastly, their customer service is horrible and take days to get a response. Also, their portal doesn't work well so their technology is bad too.
