Why Our Strips Are Different

Standard whitening strips can slide, peel, or irritate gums. Ours use an elastic gel consistency and advanced mould technology for better adhesion and more even coverage — developed by the same dental professional behind Colgate Total and Philips Zoom.
Elastic gel stays in contact with enamel throughout each session
No carbamide peroxide — formulated for sensitive teeth
No rinse needed — simple, low-effort daily routine

How Whitening Strips Work

Each strip is coated with a whitening gel that adheres directly to the tooth surface, holding the active ingredient in consistent contact with the enamel throughout the session. Unlike LED kit systems where activation is immediate, strips work through sustained, gradual contact — delivering consistent daily improvement over the course.
