"I purchased this product along with the AO Wrinkle Defense Creme. They are both going back. I have used a lot of skin care products in my time, and I think I'm pretty knowledgeable about skin care and skin care products, but this stuff is the worst I have ever used. I have nice skin for my age (63), but this stuff did absolutely nothing after using it 2X a day for nearly a month. Used in tandem with the AO Wrinkle Defense Creme, the products made my skin look absolutely lifeless and dull. My complexion has never reacted so negatively in this way to any other skin care product that I've used. It made my skin look definitely worse, not better. Back they go."
