I have this product and i have to say i don't really see the difference between when i use it and don't use it. My dark circles were still there but I will say i love the cooling and silky smooth finish it gives you so 3/5!
I don't really have dark circles, more like veins that show... this does cover them up a bit I feel and I then go in with concealer but I love how this feels under my concealer I feel like it makes my concealer last all day.
So I've had genetic dark circles my whole life, and this product perks my whole eye area up! If it wasn't for the small amount of product I would def purchase this again! Maybe when I'm not budgeting for makeup. :)
