MAC Life's Blood Liptensity Lipstick ($21.00 for 0.12 oz.) is a bright, medium red with neutral-to-cool undertones that has a lightly glossy, cream finish. It is the combination of brightness and undertone that seems to appear a bit warmer on me, though to my eye, it is neutral-to-cool. It had nearly opaque pigmentation, and the color went on evenly and smoothly while the consistency seemed to fill in lip lines and made my lips appear fuller and smoother. This shade wore well for six and a half hours and was neither drying nor hydrating. Hourglass Icon (P, $32.00) is darker (95% similar). Givenchy Heroic Red (321) (LE, $36.00) is warmer (95% similar).
