This extreme-formula, lip-plumping gloss is filled with scientifically proven plumping microspheres that explode in volume, up to 10 times, when they come in contact with water. This plumping technology is activated by powerfill®, with a trade-secret main ingredient. Sexy Mother Pucker is also formulated with a rare circulation-enhancing ingredient that gives your lips a little "electric" buzz to move more blood around the area, creating the aforementioned swelling effect.
