Skin Care Review: Sudden Change Under Eye Serum

I am a 35 year old African-American woman. In January of 2002, I purchased Sudden Under Eye Serum because I'd noticed puffiness. That was the first time I had to be concerned with any skin problems.

After about a month of using the product, I'd developed dark rings under my eyes. The rings are so dark they look black. Also, one claim for this product is you can apply it and wear makeup over it. Well after I applied the serum, it dried with a white crust.

I'd like to know what went wrong. Is this product not made for women of color? Is there something else on the market for us? And,is there something I can use to get rid of the dark rings now?
