Whitening Gels Effect:

1. With the whitening effect of the active ingredient Hydrogen Peroxide, achieve dental-level self-care at home.

2. As an OTC (Over-the-Counter) medicine certified by the Ministry of Food and Drug Safety Korea, it safely whitens teeth by bleaching stained substances, making them brighter and whiter.

Whitening Gels Usage Method:

1. Apply the gel evenly to the teeth.

Tip: If you have concerns about specific areas, you can target those areas with the gel instead of applying it to the entire teeth.

2. After applying the whitening gel to the teeth for 30 seconds to 1 minute, dry it, then wear the mouthpiece and wait comfortably for 30 minutes while whitening occurs.

3. Rinse thoroughly with water to finish.
