It evens out two-toned lips, on its own
Darker on top, pinker underneath. Most of us have it, and no nude from the counter has ever covered it without going flat and chalky. The pigment in TrueShade is pH-reactive: it goes on almost clear and settles into one even, rosy-berry tone that is built from your lips, not painted over them.
Top lip and bottom lip, one shade. That is the whole point.
