For Busy Schedules & Instant Radiance
Perfect for those on the go or prepping for a last-minute event, our Express Whitening delivers visible results in just 30 minutes. This quick yet effective session gently removes surface stains and refreshes your smile — ideal for first-time clients. And those with sensitive teeth, looking to ease into the whitening experience.
Results: Up to 6 shades lighter in one session.
Our most requested service — The Premium Whitening experience — is a full-session treatment offering deeper stain removal and more dramatic results. Using a professional-grade formula and customised application, we help you achieve a visibly whiter smile that lasts. This session includes pre-treatment care, LED-activated whitening, and a post-treatment enamel protection finish.
Results: Up to 12 shades brighter in a single visit.
For existing clients only (Within 3 months) Smiles this luminous are worth preserving. Our Maintenance Whitening sessions are designed to extend your results and maintain brilliance over time. These shorter appointments help prevent stain buildup from coffee, wine, or everyday life — keeping your smile fresh, clean, and camera-ready.
Ideal For: Clients who’ve completed a full whitening treatment and want to maintain their results all year round.
