A question about makeup products for LIPS!?

lip liner is just for people that do not have lips that make them a bit more fuller to apply lipstick on perfectly . and you need to put a concealer on the lips i know it may look like your dead and gross but the concealer on the lips cancels out your normal pigment so the color that you pick will show up to its true color on your lips.the concealer will not show after you put on your lipstick but if your wearing a lip gloss you do not need anything.
