Identification of senescence rejuvenation mechanism of <i>Magnolia officinalis</i> extract including honokiol as a core ingredient.

ABSTRACT: Reactive oxygen species (ROS) contribute to aging by mainly damaging cellular organelles and DNA. Although strategies to reduce ROS production have been proposed as important components of anti-aging therapy, effective mechanisms to lower ROS levels have not yet been identified. Here, we screened natural compounds frequently used as cosmetic ingredients to find substances that reduce ROS levels. Magnolia officinalis (M. officinalis) extract significantly lowered the levels of ROS in senescent fibroblasts. A novel mechanism by which M. officinalis extract restores mitochondrial function to reduce ROS, a byproduct of inefficient electron transport, was discovered. The reduction of ROS by M. officinalis extracts reversed senescence-associated phenotypes and skin ag
