I have extremely dry skin and lips. I’ve tried so many different lip balms like YSL, Dior, Fresh, Bobbi Brown, Chanel...you name it. Some of them were good and some of them were disappointing. But, none of those could make my lips moist aeven for a few hours. Mac Prep + Prime Lip actually keeps my lips moist for a long time and of course my lips look so nice when I put any kind of lip color on it. I love it so I’ve bought another one to give it to my sister. She loves it too. I’ll definitely get this again.
Works for me. Per saleswoman's instructions, I put on and wait a little bit and then apply lipstick. No smudge on a drinking glass. Color lasts a long long time.
