I received a deluxe sample of this product through Glossybox back in May 2014. I have always been very skeptical of serums that claim to offer anti-aging capabilities. After two months of using this product on a daily basis, I'm comfortable in saying that I do see a change in the appearance of my skin. I apply a small amount under my eyes and all over the lid. After I few weeks, I noticed a difference in the appearance of the darker areas under my eyes. It appeared lighter, and looked smoothr. The price tag on this product seems excessive, but if you plan to spend a similar amount on another product, I'd recommend giving this serum a try.
