NIMA is a teeth-whitening brand offering at-home products designed to help users achieve a brighter smile. Its range includes no-slip whitening strips, whitening pens, LED devices, stain-whitening mouthwash, whitening toothpaste, and product bundles and kits. NIMA says its whitening course involves 30 minutes of use each day for 14 days, with a visible difference often appearing within the first three days and results of up to six shades whiter by day fourteen.

The brand describes its products as enamel-safe, low-abrasion, and formulated for sensitive teeth. According to NIMA, 98% of users report no sensitivity during the 14-day course. Whitening results typically last three to six months, depending on habits such as drinking coffee, tea, or wine, or smoking; the brand recommends whitening toothpaste and mouthwash to help maintain the shade. NIMA products are made and shipped from Europe, and tracked delivery is complimentary on orders over €65. The brand also provides information about its whitening process, along with a journal, company story, and frequently asked questions.
