I'm very much the same as the first review, was a smoker for years ( am 29) and started taking my skin care seriously a few years ago after noticing wrinkles on my forehead which I guarantee are from stress. I started noticing the wrinkles under my eyes when smiling about 3 or 4 months ago and panicked. I tried a few other products with no results except irritation.
I actually bought a sample size from eBay after hours of research and reading reviews. I have been using it about 3 weeks now.
Only within the past week I started to notice how much firmer the skin around my eyes were, dark circles diminished and fine lines significantly gone down. I use it morning and night and always wear sunscreen in the day and also use a antioxidant eye cream over the serum before bed. I am so far very happy and impressed, so much so that I bought the regular size product from Sephora.
Yes the price is high but you use so little of the product each time that it lasts a significant length of time, and to me my skin care is something I will never sacrifice on again. This product is so far worth every penny. I'm going to continue using it and see how things are in a couple months and maybe do a update review! Hope this helps :)

I am only 30 years old but have pretty deep wrinkles under my eyes when I smile from years of smoking (quit 2 years ago) and lack of good skin care. When I finally took skin care seriously, I started looking for an eye cream that could help reduce the appearance of these wrinkles. I first received this cream as a deluxe sample from Sephora. I wasn't expecting miracles or instant results. But after using it for less then 2 weeks, I saw significant results. The fine lines were gone, deep wrinkles less defined and the skin became more firm. The price is insane (on Sephora it is $102 cad for 0.5oz) but I believe it is worth it for the results that you get.
