I just started using this product about two weeks ago so I can't speak to the long-term results.  I will update this review when the bottle is empty and address that issue.  So far, I don't see a huge impact on my undereye circles.  What I can say is that the eye cream is very soothing to my 47-year-old skin.  It absorbs quickly and one pump does the entire eye area on both eyes.  I have sensitive eyes but this cream has not made me itchy or irritated.  The only negative I have is the odd fragrance, which is not perfumey but not as fresh smelling as you might expect something labeled "green apple" to be.
