It is a very plesant product - makes the skin around your eyes comfortable and "rested". It is not a concealer and won't camouflage any imperfections or dark circles but I'd rather skip my concealer than this eye stick. If you prefer hydrating make-up primers this product could perfect as an eye primer.
This product really awakens the eye, I keep mine in the fridge. I use it under my concealer and I think it helps my concealer go on smoothly and stay put, plus it feels amazing! I treat this as my AM eye moisturizer. It doesn’t last long, 3 months top, which in my opinion makes it quite expensive.
