I've been using this product around 2 weeks now, and I noticed definite changes in the skin by my eyes. After applying in the morning and night, fine lines seem to disappear. I have already recommended this product to others and will definitely buy again. It is a great value, and it has worked better than any department store product I have used to date. I have noticed, however, that the effects wear off over time...by the end of the day I notice the fine lines have returned again.
