Watch: how our LED whitening system works without the sensitivity
Our clinically-proven whitening systems use Sodium Percarbonate instead of harsh high-peroxide formulas — releasing oxygen to break down stains effectively while keeping sensitivity low.

A permanent knowledge base to help you choose the right whitening method, understand the ingredients, and get the most from your results.
Gentle whitening systems using Sodium Percarbonate or PAP-based ingredients are typically the lowest sensitivity options. Gradual methods like whitening strips are also well-tolerated. Controlled whitening kits using Sodium Percarbonate are designed to balance results with comfort for most users.
Many people prefer alternatives like Sodium Percarbonate-based systems, which release oxygen to break down stains while aiming to reduce discomfort compared to high-peroxide treatments. PAP-based products are the gentlest option for daily use.
The best method depends on your goals. Whitening kits provide the fastest results — typically visible within 7–10 days. Strips are easier to use daily and suit gradual whitening. For the best long-term outcome, combine an initial kit treatment with a consistent daily maintenance routine.
Whitening kits generally deliver faster and more noticeable results, while strips are more convenient for daily use and have a lower sensitivity profile. For most people, the strongest long-term approach is to use a kit for initial treatment and strips or maintenance products to sustain results.
Yes — modern whitening products are safe for most healthy adults when used as directed. Whitening works on stain molecules rather than the enamel structure itself. The most common side effect is temporary sensitivity, which typically resolves within 24–48 hours after a session.
Results typically last 3–12 months depending on the method and maintenance routine. LED whitening kits tend to deliver longer-lasting results (6–12 months) than strips alone. A consistent daily maintenance routine significantly extends brightness between treatment courses.
