Do not expect this cream to make your under eye circles disappear. This is a great cream for moisturizing the eye area and I find with daily use it combats puffiness and sometimes, slightly improves the purple/blue tone under my eyes. Not a magic bullet by any means.
I have tried so many high-end eye creams over the past 10 years, and nothing comes remotely close to this product. I saw a difference after just a few weeks of using it and results continue to be amazing. The price is hard to swallow, but I promise you, it is worth every penny.
I'm 35 and have been using this product for several years now. I've gone back and forth with other eye creams, and La Mer is the only product that I've actually seen results. Highly recommend! It really is worth every penny.
