LISTERINE® Antiseptic 30-Second Exposure

LISTERINE® Antiseptic 30-Second Exposure

Why rinse for 30 seconds?

For maximum efficacy, the dosing of LISTERINE® Antiseptic rinses is 20mL for 30 seconds, twice a day. What happens in those 30 seconds, and why is only 30 seconds of rinsing necessary?

In just 30 seconds of a full strength rinse, the technology behind LISTERINE® Antiseptic damages the cell surface of bacteria, interferes with growth, and increases the amount of time it takes for the bacteria to regrow11, 12, 15-18 as well as yields greater bacterial kill, and greater plaque reduction.19
