• A photoprotective and antioxidant agent. Palythine absorbs ultraviolet radiation (UVR) energy and dissipates it as heat. It also has antioxidant mechanisms, such as direct chemical quenching and Nrf2 pathway activation. Palythine reduces cell death, DNA damage, inflammation, and oxidative stress, and is promising for research on skin-related diseases like skin cancer, photoaging, and photosensitivity disorders.
