I just wanted to add that I like the mattene formula more than the prolongwears. Mattene is slightly thicker, less creamy and less slippery, so they apply nicer. Prolongwears are thinner and creamier so it has more slip on the lips. It is harder to apply evenly. I also hate the packaging on the prolongwears >_< Now if they did it in a slimmer tip, I would be buying more. Mine would scroll up but wont come back down, so you have to be careful. If you scroll up too far, it's over. lol
Not a stupid question at all. They are a long-lasting formula, but they're more of a satin than a matte finish. They're not drying- in fact they're fairly comfortable, assuming your lips are in reasonably good shape. The colour tends to be very pigmented. The colours tend to be creams- a little bit flat but nicely pigmented. They remind me a little of the satin-finish MUFE lipsticks.
