I have been using the Patricia Wexler M.D. Undereye Brighening Cream for about two years now and I am so very satisfied with this product. You can find it at your local Bath & Body Works Store or on their website. It took at least one week before I started to see results. I had very dark circles underneath my eyes. I always looked very tired and the dark circles weren't complementing me at all. When I would put my make up on, my eyes would like I had a bruises underneath them until I started using this eye cream. I use this product once in the morning and before I go to bed at night. When I wake up in the morning, I look like I've had a good night's sleep. No dark cirlces anymore thanks to this great product. I am very dedicated when using this product. I don't miss an application whatsoever. One of the things that I like about this product is that it absorbs quickly and I can proceed with my makeup application. There's no greasy feeling and my eyes look younger. I would recommend this product to anyone who is battling with the dark cirlce situation.
