I purchased this gloss in Belissima. My skin is light and pink, and I thought this would be a nice shade. It is- but it's very light and natural. It enhances the natural color of my lips, rather than making them a darker color. I've already ordered Rouge Velotre to see if that one will show up a bit more.
I love the way it goes on- smooth, not sticky, and with just a little shine- not that tacky glossy look. It almost feels like a balm once it's on, rather than a gloss.
As for staying power, it doesn't transfer to my teeth, and it doesn't create that sticky line on my inner lip. It doesn't last incredibly long, but I don't expect a gloss to.
