FORMULA & INGREDIENTS
The kit features a professional whitening complex built on:
- Carbamide Peroxide (35%) — clinical-strength formula that gently lifts surface stains and deep discoloration without causing sensitivity
- 16-LED Whitening Light — medical-grade, waterproof, USB-rechargeable, activates the gel to accelerate whitening
- Aloe Vera & Xylitol — soothes gums and balances oral pH for a comfortable whitening experience
Crafted by NYC dentists — developed by Dr. Jan Linhart and team, backed by 40+ years of cosmetic dentistry expertise.
HOW TO USE
Use the syringe to apply a thin, even layer of gel to your teeth. Turn on the LED light and leave for 10–15 minutes. Remove, rinse, and wipe away excess gel. Brush with LINHART Tooth Whitener Gel and Toothpaste morning and night to preserve results.
For maintenance between treatments, add a drop of Tooth Whitener Gel every time you brush until your desired shade is achieved.
