I had to try this product despite the cheesy Twilight-esque marketing. The new Just Bitten lipstains from Revlon are supposed to leave your lips stained with rich color. The double sided lipstains look like a marker on one side and packs a balm on the other side. I love the way lipstains are meant to look (a simple, sheer wash of color) but done wrong and you end up looking like you've been sipping on Kool-Aid all day. I've had a pretty sour experience with the Cover Girl lipstains, which were poor in pigment, drying on the lips, and tasted like a Sharpie marker, so I approached this product with a bit of cynicism.
I applied the Revlon lipstain in Passion on exfoiliated lips and was surprised at its rich color. Without the balm applied, the lipstain gave me a great matte finish of color on my lips and the balm added just a small bit of shine. I like the lipstain more than I thought I would, but to be honest, I'd rather put on some lipstick or lipgloss. If an affordable lipstain is what you are looking for then this is a great one to start out with. Be warned though- the darker colors are very pigmented and will stain your lips for hours!
