I received this product free and complimentary from the brand itself and 0.8 liter. I already have the cream and the serum for this same line of products so I got the patches which is made of the same ingredients now there is a lot of decent ingredients or low risk ingredients in this product and I have seen a lot of good reviews and this is a new innovative technology I hear that there is some controversy about the main ingredient DW-EGF, which I have to do more research on it myself but I have no complaints after using this line of products
