This product should come with a warning: prepare to drown in compliments! I use it to open up the arch beneath the eyebrow, and to dab in the dark inner corners of the eyes. It makes the eye open and brighten. I tried it on my sister-in-law, and her neighbour asked her if she'd had a face lift! Even though the effects are dramatic, it is light and easy to blend. It can be so subtle that you wouldn't know it's there, except that you simply look lighter and brighter.
