Skin aging is caused by various causes other than aging, and photoaging due to ultraviolet rays is also known in recent years. Among ultraviolet rays, UVA causes a blackening phenomenon and promotes production of reactive oxygen species (ROS) through activation of NADPH oxygenase and the like. ROS causes photoaging of the skin such as causing DNA damage. In such a background, studies on components having an inhibitory effect on ROS production induced by ultraviolet rays have been advanced, and external preparation compositions for skin or hair care have been developed, but the effects thereof are not necessarily satisfactory.SOLUTION: To provide a new external preparation composition for skin or hair care, suppressing ROS production by NADPH oxidase activity inhibition and preventing photoaging by formulating trimethoxybenzylidene pentanedione.SELECTED DRAWING: Figure 1
