Science
Mechanism of Action
This compound acts as a UV absorber, shielding cosmetic formulations from degradation caused by UV light. Its primary mechanism on skin involves a ring-opening reaction triggered by UVA, UVB, and/or UVC rays, generating colored merocyanine dyes. This dynamic color change provides a direct, visual indication of UV radiation exposure.
