I've have been using this for about a week and a half. It's currently only available through QVC, but it's supposed to hit other venues in February of next year. This is, so far, the only Rare product I have not reacted negatively to.
I'll do a more thorough review in a few weeks, once I've seen if it does anything for my dark circles. But I have noticed that right away, the skin around my eyes is much more moisturized. I have another eye cream from Basq that is great for puffiness, but not so moisturizing. In the desert winter, I need all the moisture I can get!
