LipSense is a liquid lip color that can last from 4-18 hours with just one application. It works as a two part system, part 1 being the color which bonds to the lips and part 2 bring the gloss that moisturizes the lips and protects the color from saliva and the external environment. Together they create a long-lasting, kids proof, smudge-proof, waterproof lip color that won’t dry out your lips and won’t come off until you take it off!
