The Purple Teeth Whitening Pen is a convenient solution designed for adults to instantly brighten their smiles by removing surface stains from coffee, wine, pasta sauce, and more. This pen uses color-correcting technology, where the purple gel neutralizes yellow stains, making teeth appear whiter. Unlike messy strips, the pen allows for precise application by twisting the tube to release the whitening gel directly onto each tooth. For best results, clean the brush tip with a dry tissue after use and ensure the cap is dry before replacing it. Note that this product offers temporary whitening and is not a permanent treatment. For any questions, customer support is readily available to assist. Your smile is our glory. :)**INGREDIENTS:** Sorbitol, Aqua, Phthalimidoperoxycaproic Acid, Propylene Glycol, Glycerin, Potassium Nitrate, PEG-8, Hydroxyapatite, Cellulose Gum, Hydroxyethyl Cellulose,Xanthan Gum, Saccharin Sodium, Menthol, Methylparaben, Aloe Barbadensis Leaf Juice, Chamomilla Recutita(Matricaria)leaf Extract, Punica Granatum Seed Oil, Sodium Bicarbonate, Propylparaben, Cl17200/D&C Red No.33, CI42090/FD&C Blue No.1.
