My review is for the shade Parisian Passion (005).
I'll admit I thought the name "Moisture Stain" was a little funny at first, but I'm glad I bought it regardless!
It's basically a stain, but it feels very "cushiony" and almost like a mix between liquid lipstick and a good, non-sticky gloss.
The product almost feels like a gel when you first apply it, especially when applying a good layer of product. Once it's actually distributed over the lip and has a moment to set, it seems to sink in and feels pretty natural. The colour is very saturated and rich, with no streakiness, and it's very easy to apply as little or as much as you want. I apply this with a lip brush sometimes, for a lighter stain, or use the original applicator to get a more full-on colour. Either way the colour always looks even, with a beautiful shine that lasts much longer than I expected. The stain also lasts for a couple of hours I'd say, or less with drinking/eating.
I love the shade I got - it's a gorgeous plum/berry shade that leans more purple. There isn't any shimmer in this one, but there is some in other Moisture Stain shades. Overall, I am very impressed and definitely want to pick up at least one more of the shades in this line!
