I love "one&done" eyeshadows, and being a firm supporter of Jouer in general, and owning a great many of their products, this eyeshadow is everything for me.
Their shimmers are all "one&done" shades, I just use a fluffy brush all over my lid. But, for when I do want to glam it up, I have several-all interlinked into their own little palette, made by me-that I use to highlight, a matte one for use in the crease, and dark, shimmery one to line with.
These aren't the most pigmented shadows I've ever tried, but the brand ambassador and creator, Christina, created them that way to be foolproof so women off all makeup walks of life can use it. However if you like a stronger look, they're easy to build and blend.
