I've been using Mac lipstick products for some time now but I had no idea why sometimes my lips would dry out or the lip color would crack. I was told by a sales rep that I should apply the prep and prime first followed by my lip color I purchased two. This product is amazing it keeps my lips moisturized throughout the day no cracking or peeling. Goes on smooth and eliminates that white residue! This is a must have when wearing your favorite everyday lip color !
Maybe I used it wrong, but I bought it due to all the positive reviews about stopping lipstick feathering and making color go on smoothly. When I used it, it seemed to make the lipstick slide around more and look messier? I have lips on the smaller size and don't use bright colors. So for me I returned.
