An arctigenin derivative used for anti-aging treatment, including protection of the skin from the sun and recovery of skin elasticity. A variety of fatty acid ester derivatives, alcohol ether derivatives and alkylated derivatives are used as the arctigenin derivatives. Agents for controlling ET-1 production, elastase inhibitors, and anti-inflammatory agents are prepared. Such arctigenin derivatives are particularly useful as an external agent for the skin, such as an anti-inflammatory external agent, a sunscreen external agent, or an external agent for recovering elasticity.
