Backed by "science"? HA
This company says it's backed by science and they gloat about their Harvard and Stanford "scientists". When you start the product you take a quiz so it's "formulated" for you. They also gloat that they are the only ones to take your environment into consideration. I took the quiz and it came back saying my location has a low UV index. Well I live in Colorado which has the most sunny days in a year of any state, plus it's high altitude . . . I mean, you can google it but the index is definitely not low and actually it's HIGH. Lost total credibility right off the bat. Backed by "science", I don't think so, this company is a total scam. I hope you don't get skin cancer from them "formulating" a low UV index.
