Answer: MAC's Lusterglass lipstick fits in a specific category. MAC calls it a Lipstick Luster while other brands refer to it as “glossy” or “shiny.” The formula is semi-glossy and usually has a subtle color payoff. Most of these lipsticks have hydration benefits, so these lipsticks are ideal for those who want a lipstick but struggle with constantly dry lips.While I think the Lusterglass lipsticks have a great color payoff, it's not as bold as some of their other lipsticks.
