If you’re on the hunt for a blacker-than-black mascara that leaves lashes looking tinted and fabulously flirty, M·A·C Haute & Naughty Too Black Lash, $48, hit counters this week. They say: “The velvety formula coats from root to tip, and leaves lashes silky-soft with conditioning ingredients that prevent dryness, spikes and hardening.”    We say: Thank you MAC for dishing up another great lash groomer.
