I've used Olay Definity for a couple years now. It's a part of my daily routine (which is not obsessive.) It was a slow progression of change, but I can clearly see diminished lines in my face and smoother skin. The creases in my forehead have lessened as well. A bit of advice: put a little extra in your hand each day and rub it on the backs of your hands. Even my hands have improved from this product!

 Be sure to check labeling. This is available regular or in an SPF15 formula.
