I have enjoyed this product. It provides a nice amount of moisture to the under eye area. I have sensitive eyes and have struggled with finding an eye cream that doesn't give me an allergic reaction, but the all natural ingredients get along well with my eyes. I haven't noticed any change in under eye color or firmness, just moisture. But this eye cream will last you FOREVER. I've had mine for probably 6 months. I use it morning and evening and it still looks like I've barely touched my jar. When I finish this jar, I intend to purchase another Mario Badescu eye cream to see if I can help my darkness under my eyes, firmness, or fine lines.
