Hydrogen peroxide forces open dentinal tubules
Hydrogen peroxide at 6–35% concentration forces open dentinal tubules

The Science
Every Twinkle White kit is built around four principles: activation, safety, speed, and NZ craftsmanship.
Hydrogen peroxide at 6–35% concentration forces open dentinal tubules
LED light at 460–490nm activates gel with very little heat and no acid
Carbamide peroxide whitening gel, not high-concentration hydrogen peroxide
Sessions are capped at 10 minutes — not 30+ like some whitening kits
Heat from UV lamps activates peroxide too aggressively
Sessions stop automatically after 10 minutes, so contact time stays short
If you have experienced sensitivity from high-strength whitening strips, this section explains why it happens, and how the gel and short sessions are designed to minimise it.
Blue light at 460–490nm shines from the mouthpiece onto the tooth surface.
The light activates the carbamide peroxide gel on the tooth surface. No acid, no abrasives.
Surface and sub-surface stains (coffee, wine, tannins) are lifted as the gel activates.
A subtly brighter surface, designed to minimise sensitivity.
Traditional whitening strips use high-concentration hydrogen peroxide or acid, held against the teeth for long periods. Twinkle White® pairs a carbamide peroxide whitening gel with blue LED light at 460–490nm in a 10-minute session, so contact time stays short.
Our gel is a carbamide peroxide whitening gel with no citric acid and no abrasive microbeads. Blue LED light activates the gel — the same wavelength principle used in dental settings, adapted for home use. The full ingredient list is below.
Blue LED light produces very little heat at the tooth surface, which helps keep each 10-minute session comfortable.

Full Ingredient Transparency
The active whitening compound. Releases slowly, and the 10-minute session keeps contact time short.
Humectant that keeps the gel evenly hydrated across the full 10-minute session.
Cosmetic-grade viscosity agent. Holds the gel in even contact with every tooth surface.
Purified base solvent, free of minerals that could interfere with formula stability.
Cosmetic thickening polymer that gives the gel its smooth, brush-on consistency.
Cellulose-derived stabiliser that keeps the formula uniform from first use to last.
Helps the gel adhere evenly to the tooth surface during the session.
Used in trace amounts to balance the gel within the cosmetic pH range.
Provides a clean, cool sensation and contributes to the mild mint finish.
Every mouthpiece touches your mouth for 10 minutes per session. The Signature Kit includes a UV disinfecting charging case: rinse the device, pat it dry, then place it in the case for a 5-minute UV cycle while it recharges.
Self-cleaning between sessions
Rinse the mouthpiece, pat it dry, and place it in the case. A 5-minute UV cycle runs while it recharges. No wiping, no alcohol wipes.
Rare among NZ kits
As far as we've found, we're the only NZ kit with a UV disinfecting charging case.
Included with Signature Kit only
The UV disinfecting case is exclusive to the $129 Signature Kit. Black Edition and Advanced ship without it.
Most people find it comfortable. High-concentration peroxide strips are the usual cause of whitening sensitivity. Our kits use a carbamide peroxide whitening gel with blue LED light at 460–490nm in short 10-minute sessions, designed to minimise sensitivity. If you have existing sensitivity, start with 5-minute sessions and build to 10 minutes over the first week.
Use it as directed: one 10-minute session a day. Enamel damage from whitening is linked to high-concentration and acidic products; our gel is a carbamide peroxide whitening gel with no acid. If you have concerns about your enamel, speak with your dentist before you start.
Dentist trays typically use 10–35% carbamide peroxide, and strips use 6–14% hydrogen peroxide with adhesive that contacts gum tissue. Our kits use a carbamide peroxide whitening gel with blue LED light in a universal-fit tray, in short 10-minute sessions designed for comfortable daily use at home.
7 days with consistent daily use (one 10-minute session per day). Most customers report a clear, visible improvement by day 7. Results vary with starting shade and staining, but the 7-day cycle is what our formula is calibrated for. Top up weekly to maintain the lift.
