DescriptionHaloSmile is a new way to instantly get a whiter smile. Inspired by nature, the second product ingredient, after water, is the naturally occurring calcium mineral found in your teeth. It is a unique cosmetic that creates a light and tasteless layer over the surface of your teeth—covering stains instead of removing them, for an instant white smile without sensitivity. An application is as quick as drying your teeth, evenly brushing on the product and waiting 1-2 minutes for it to dry; and within 8 minutes, you can have an instantly whiter smile! This Natural White formula is for those with darker teeth or just want a subtle boost.
