Boutique Whitening by Day is a 6% hydrogen peroxide gel. Hydrogen peroxide is inherently unstable and will break down immediately once you place the whitening trays in your mouth. The majority of the peroxide will be spent within the first 20 minutes of wear, but to experience the full effect of the gel, we recommend at least 1 to 1.5 hours of wear time.

Boutique by Night has several different protocols, all designed for a minimum of 4 hours’ wear time, but best results will manifest from keeping the trays in overnight, so you can whiten as you sleep. Wearing for 6 hours or more at night will typically yield better results.

We have a 10% carbamide peroxide gel, or a 16% carbamide peroxide gel – both designed to be worn overnight. These are the equivalent of 3.5% hydrogen peroxide and 5.7% hydrogen peroxide, respectively.

Both gels will give you a fantastic white smile, but the 16% will get you there a little faster. If you suffer from sensitivity, the 10% is a better option for whitening your teeth.

Boutique also manufactures a 4.25% Hybrid Pro teeth whitening gel. This is a blend of 4.25% hydrogen peroxide and 4.25% carbamide peroxide. This gel is designed to be worn overnight and delivers a gentle nudge with the hydrogen to get things started, whilst the carbamide slowly ramps up overnight. This is a powerful formula, delivered gently to ensure excellent whitening, whilst minimising side effects.
