The instant whitening wand! Glostik is a pearlescent tooth gloss designed to make your teeth instantly whiter for a picture-perfect glow. How does Glostik work? Similar to lip gloss, tooth gloss works by reflecting light to make your teeth appear whiter and give your smile the glow it deserves. The pearlescent glossing formula that covers your teeth creates an instant whitening effect. How and when should I use Glostik?: Before use, thoroughly dry teeth. Apply a thin layer of Glostik from top to bottom on each tooth, using long, even strokes. Once applied to all teeth, close mouth to smooth the product evenly across the teeth. Glostik can be reapplied as needed and used as often as desired. It is perfect for on-the-go touch-ups and getting ready for special events!
