MAC Star Memoir Lipglass is a medium-dark berry with subtle, cool undertones and fine, violet and pink pearl throughout. It had medium color coverage with a smooth, light-medium consistency that was moderately tacky and felt thicker, but it was very comfortable to wear and smoothed out some of my lip lines. There was a bit of gloss that sank into the deeper lip lines on my lower lip, but all of my lip lines seemed finer. It wore well for five hours and was hydrating over time.
MAC Starfucker Lipglass is a medium-dark purple with subtle, warm undertones and flecks of lighter violet micro-sparkle. It had semi-sheer color payoff that applied unevenly, sank into and emphasized my lip lines, and was generally an unflattering product to wear on its own.
If you apply liner all-over or use it on top of a lipstick, you’ll have much better luck, though I would take care to apply a bit less as the heavier, tackier formula can sometimes cause satin and cream-finish lipsticks to have too much slip! It lasted for five hours and felt moisturizing while worn.
