I spent over 12 years in the cosmetic industry working with all the big guys. It’s a bunch of BS, there is little to no science, and Marketing rarely pays heed to the limitations of the products except when a claims lawyer tells them they need it. Water is the key ingredient, followed by nutrients, which are absorbed best through the intestines. I still use basic moisturizers for comfort (I mean who wants to deal with dry hands and rough itchy skin?) but the idea that this stuff enhances appearance is a joke.
