I have been using every product of the ProX line for 3 months now. Not only have I seen no improvement, but my deep wrinkles are worse, and I use the Deep Wrinkle Serum 2 x a day! I first used the starter kit for the 30 days, didn't like it and returned it and got my money back. I then thought maybe I needed to give it more time, and bought every product in the line. The products are very greasy, so not good under make-up, and the eye cream is also not good under my shadows. I expected more from Olay, but I have never been happy with any of the Olay products, I guess I just fell for all the hype...
