I got this a couple of months ago as a freebie when I bought another Trilogy product and have been enjoying it.
The packaging is attractive, and the roller ball makes it really easy to use.
I apply a few swipes under and over my eye area every night after cleansing, toning and applying serum. It feels instantly cool and refreshing and seems like it does brighten the whole eye area up a bit.
To be honest I have not noticed and really obvious benefits since using this product, but I really like using it and will continue to do so.
I LURVE this eye concentrate. The rollerball applicator is fantastic - allowing you to gently and accurately apply and smooth the liquid on without pulling the delicate skin around the eyes with your fingers.
For me it's the wonderful cooling and soothing feeling when you first apply it that's the best part. A wonderful reviver.
Tips: Be careful around the lash line - I accidently got some in my eye and it was a little stingy.
