I've always been a fan of MAC and their products. This primer is no exception. It glides on smoothly and doesn't take long to get tacky enough to apply your lip liner and color. Online other lip primers, it doesn't make your lips too tacky that your lip color doesn't glide on your lips. I'm a red lip color lover and this primer keeps my lipstick from feathering. I've tried others for the past few years but I ALWAYS go back to MAC.
My lips tend to be very dry and sometimes chapped during the cooler months. I am always on a campaign to keep them hydrated for lipstick application. While I've only tried the face primer from MAC (I like it) and own just one of their lipsticks, I thought I'd give this a try. So far, I've found it works well. The color of my lipstick on my lips is more true, feathering of red colors (my favorite) has been corrected, and my lipstick stays on longer. Thumbs up.
