Absolutely. We actually use the same process and whitening ingredient that dentists use. Peroxide-based ingredients (such as carbamide peroxide and hydrogen peroxide) are scientifically proven to whiten teeth.
Of course. We make sure all our products are safe for you and your teeth. Our active whitening ingredient is what dentists use for whitening procedures, and is scientifically proven to be safe for teeth whitening. The Holo formula also contains potassium nitrate (the active ingredient in Sensodyne!) to prevent sensitivity.
The Holo mouthpiece uses LED light (no harmful UV!). If you have any questions or concerns prior to use, please consult your dentist.
