Great product! I have used many a skin care product and this was by far the best one. But because its so expensive i have to buy it sparingly. (Im not a high roller) I have ordered this product twice in the last year and it works right away. The problem is you really have to use them all in 30 days or the pads will dry up on you. This is dissapointing since i really dont need to use them everyday. Nonetheless this product works...if i had the money i would keep a ready supply in my cabinet.
Positive
