Why Stability Matters：
Imagine a teeth whitening strip that loses its potency after a few weeks. That's why stability testing is paramount.
It helps us determine if our product properties remain stable over an extended storage period, mimicking real-world conditions from warehouse to consumer.
To ensure consistent quality and safety, we strictly test all our teeth whitening products at different temperatures (30°C, 45°C, -8°C and room temperature) for a period of 1 to 3 months.
This crucial step in our new product development and formula reform ensures you always receive a consistent, high-performing product.
Stay tuned as we continue this series and unveil the essential tests behind every product we make.
