They support you in achieving white, beautiful teeth and brightening your everyday life. 【A New At-Home Whitening Care: Lift and Remove】The high-concentration cleansing agent, sodium bicarbonate, adheres to and lifts stains and yellowing on teeth. Brushing afterward restores your teeth's natural shine. 【Easy 3-Step Care】Easy at-home whitening care with just three steps: apply, wait, and brush. Simply apply the sheet to your teeth, wait about 20-30 minutes for it to settle, and then brush. This is a simple care routine, with 28 sheets (14 sets) to help you maintain it consistently. 【Precautions for Use】1. After using the sheets, some paste may remain on the tooth surface. Brush thoroughly with a toothbrush to remove any remaining paste. 2. When applying the strips, if air gets trapped or if parts don't adhere due to saliva, the whitening may appear uneven. With continued use, the color will even out, but it's recommended to wipe your teeth with a tissue before applying the strip to remove moisture and prevent air bubbles. 3. The sheets are for single use only. Please do not reuse them. 【Safe 12-Free Formula】A 12-free formula designed with your teeth in mind. Free of preservatives, mineral oil, UV absorbers, petroleum-based surfactants, silicones, parabens, foaming agents, synthetic colorants, abrasives, ethanol, animal-derived ingredients, and sulfates.
