Revlon Colorburst Lip Butter in Pink Truffle is a glossy pinky-brown lipstick. Most of the Lip Butters start out sheer but their coverage can build, but I get decent coverage from Pink Truffle with just one coat.
Pink Truffle is the closest to a rosy shade there is in the current Lip Butter line.
Pink Truffle will be a good MLBB option for a wide variety of tones, I would think. I'm very pale and cool-toned and must be very careful with browns, and this isn't the most flattering with a thick application. If I dot it on lightly, though, it looks glossy and pouty and everything MLBB products are supposed to be. The texture is shiny and very emollient. The tint and feel fade evenly but fairly quickly. There's a mild sweet scent that is barely noticeable. I love the magnified window cap but am not fond of the packaging... only an aesthetic quibble that would bother me more if I had to pay more for it.
