FAQ
The full Platinum Kit — a wireless BLK Light 2.0 LED mouthpiece and two Platinum Gel Pens — plus a 14-pack of Platinum Strips in your chosen flavour. Everything you need to whiten at home, and save $29 vs buying separately.
Most people notice visible whitening within a few sessions, with optimal results after 7–10 days of consistent daily use.
Yes — our 6.9% hydrogen peroxide formula is dentist-developed and enamel-safe. If you experience sensitivity, use every second day and build up.
Both! Use the Kit at home for the most powerful results, and grab the strips for quick top-ups or whitening on the go. They use the same 6.9% formula.
Charge via USB-C (~3.5 hours) for around 6 uses. It has a built-in 25-minute timer and powers off automatically.
Whitening only works on natural teeth — it won't change the colour of veneers, crowns or fillings, and won't damage dental work.
Rinse the mouthpiece after each use and store the kit, pens and strips somewhere cool and dark — the fridge is great for keeping the gel at its best.
