In times of a quickly changing environment due to global industrial growth, the burden of pollution is growing. A high degree of pollution, associated with industrialization, has an impact on our skin health Therefore, to remain a functional barrier for the body, our skin needs additional protection.

The effects of pollution are widespread, though common factors include ROS (reactive oxygen species) and RNS (reactive nitrogen species). These reactive species are known to increase stress and cause damage to the skin resulting in a weakened defense and increased risk for infection.

Plant polyphenols such as naringin and chlorogenic acid have been identified as beneficial for the integrity of this defense. Therefore, in this study we aim to determine whether Grapefruit and Green Coffee extracts can diminish ROS and RNS levels and support cellular defences.
