Swish for 30 seconds, spit, and watch the yellow tones visually disappear.

VIO is a purple color-correcting mouthwash in single-use sachets. It works on the same color science as purple shampoo: violet sits directly opposite yellow on the color wheel, so when you swish our violet rinse, it deposits optical brighteners that visually neutralize warm, yellow tones — leaving a cooler, brighter-looking, high-gloss smile in 30 seconds.
