Stunning When It Works
I tried this with my friend. Either not our color or formula, or both. We had a third friend try it, and it was perfect. The effect was completely different on her than on us. Her kibbie type is soft classic, while I'm a classic and my friend (who didn't look good with it) is a dramatic classic. Usually I can pull off a wide range of styles, colors, and so on, but not so with this product. Usually my dramatic classic friend looks good with matte lipsticks. For some reason it looked flat, cheap, and something less exciting, like a balm instead of a liquid lipstick on us. Whereas on our soft classic friend, it was everything we'd expected and wanted it to be.
To summarize, it's definitely not a one-size-fits-all product, but I wouldn't say it isn't worthwhile, since when it fits it fits just right.
Side note: the cap is top-heavy; my friend doesn't seem to prefer using it, and the packaging completely works like every other product without it, so it's not entirely necessary of a feature.
5 stars for the product because it is great on certain people.
