This allows for effective application of the gel to specific areas of the teeth, ensuring that every visible part of the smile is treated and whitened, leading to a more uniform and bright appearance. 1. The Dazzling White No Sensitivity Advance Natural Instant Whitening Pen is designed to provide a safe and gentle teeth whitening experience. With just one minute of daily use, users can achieve noticeable results, with teeth becoming up to 4 shades whiter in just one week, making it an effective solution for brightening smiles. 9. After applying the gel, users should keep their smile for 30 seconds to allow the whitening gel to dry on the teeth. It is recommended to rinse the mouth after half an hour and to avoid eating or drinking for at least one hour post-application to maximize the whitening effect. 8. To use the whitening pen effectively, users should shake it well for 5 seconds and twist the base several times until the gel covers the brush tip. A thin layer of the gel should then be applied to the teeth, avoiding contact with gums or lips, ensuring a precise application.
