Everyone in my family suffers from dark undereye circles. Even my son has had dark circles since he was young. I have tried so many products and had just about given up on finding anything that made a difference for me. I heard about Olay Definity Eye Illuminator from a friend who raved about it and I had noticed a change in her appearance. I purchased it thinking it wouldn't work for me but to my amazement it has made a big change for me. I think one of the best things about this product is it doesn't take forever to notice a change. I really started to see a difference within a couple of weeks....
