Recently I've heard from people my eyelids had a very dark tint, giving the impression I have make-up on. I decided to try if a white tone up eye serum would maybe help with the darker skin there. I must say I've been using this for only a week now, and I'm quite happy with the results. My eyes do look brighter, or maybe it's a placebo effect and I'm just imagining it all, and feel more refreshed in the morning. 1 pump is more than enough for both eyes, especially if like me you layer it with an eyecream afterwards. The product doesn't sting to the eyes. My only complaint is that is has a floral scent, that is kind of remindful of a "pot-pourri" scent.
