Listerine for Blisters
While Listerine works as an effective breath freshener, it can also help with those pesky blisters. Take a clean cotton ball and get it moist with some of this mouthwash. Simply dab your blister a few times with the moist cotton ball, three times daily. Do this until the blister is no longer painful. The coolness of Listerine helps to soothe your blister and alleviate the pain. The alcohol present in the Listerine works to dry out the blister so it goes away.
