Double White: Efficacy Testing for Teeth Whitening
Discover Double White's Efficacy Testing in action! This video scientifically proves how our teethwhiteningstrips deliver remarkable, long-lasting results. Achieve a visibly brighter, more confident smile.
In our lab, we don't just hope our teeth whitening products work. We prove it with data.
Our efficacy test uses exogenously stained bovine teeth, replicating common enamel discoloration. After applying samples, we:
- Take high-resolution photos over time
- Use a colorimeter to detect precise shade changes
- Measure both appearance and color difference
This controlled testing helps us evaluate how effectively and consistently our products whiten teeth.
