Mechanism: The device works by applying gentle, pulsating vacuum suction to expand the capillaries in your lips, which increases blood flow and causes them to appear fuller.
Design: It typically features a soft, food-grade silicone mouthpiece shaped to fit the lips and a main body housing the motor and control buttons.
Operation: Users select from multiple suction levels (usually low, medium, and strong) via a button on the device.
Results: The plumping effect is temporary, usually lasting for 1 to 4 hours.
