I've been buying Stila Convertible color products for years. They're versatile and some can be used as blush and lipstick. Illium really just works on my cheeks, it is far too light for my lips (red hair, fair skin). Others, like Poppy need to be applied carefully to cheeks or they'll give that "Baby Jane" look. Poppy is a better color for lips although it is somewhat drying and doesn't last long in lips. I wouldn't call it a stain, but it does last for a while - just not THAT long. For that reason, I always need at least one or two in my makeup bag. I've struggled to find a color that works well on lips and cheeks.
