Photostability is essential to ensure that sunscreen products maintain their protective properties after UV exposure. With global regulatory requirements constantly changing and the UV filters being scrutinized, formulators need to try new UV filter combinations and confirm that their UV filters are compatible or that their photostabilizers are working efficiently.
Our laboratory evaluates:
- UV Filter stability under Natural sunlight
- UV Filter stability under simulated sunlight
- Loss of SPF or UVA protection after irradiation
- Compatibility of active and inactive ingredients in finished formulations
This testing helps confirm that your formulation provides consistent and durable protection for consumers whether tested indoor or outdoor.
