I have been using the product exclusively at night now for the past 3 weeks. I have some stubborn wrinkles on my forehead and some big smile lines. I do love the way the night cream goes on and I will continue to use until I finish the bottle to make my final determination as to its efficacy. I still have those stubborn lines, but I think they have diminished a bit, not sure.
Bottom Line: Yes, I would recommend this to a friend
