Its a nice product and does help make you look more awake however it doesn't take the place of concealer. I moisturize my face and then put this on under my eyes and then do my makeup. I have noticed that my dark circles aren't as visible after using it for a few weeks but it wasn't a noticeable difference after the first or second use at all. I like the metal tip applicator because it provides a cooling effect that feels really good. Hope that helps a bit!
