Boutique Whitening Hybrid 4.25% 4x3ml kit

Unique to Boutique is the Hybrid Pro formula. A secret blend of 4.25% hydrogen peroxide and 4.25% carbamide peroxide.

This is a dual-action gel delivering the best of both worlds. The hydrogen starts to whiten immediately and is compounded by the slow release

carbamide, to give a gentle action but powerful results. Ideal for those that cannot tolerate overnight wear but struggle with sensitivity.
