PROBLEM TO BE SOLVED: To provide a skin external preparation having a high moisturizing effect, a synergistically improving effect on skin aging symptoms such as wrinkles and an improvement in skin roughness. SOLUTION: Skin is obtained by using mock extract and one or two or more kinds selected from commonly used cell activators such as various crude drugs, plant extracts, ceramides, yeast extracts, nucleic acids and hydroxy fatty acids. By containing the composition in an external preparation, an excellent moisturizing effect can be obtained, and a synergistic improvement in the effects of improving skin aging symptoms such as wrinkles and improving skin roughness can be obtained. The mock extract is obtained by removing a low-polar fraction from a polar solvent extract of mock by supercritical extraction using carbon dioxide as a solvent, or is obtained by removing a low-polarity fraction by supercritical extraction using mock in carbon dioxide as a solvent. After removing the polar fraction, it is preferable to use a purified mock extract obtained by extraction with an aqueous solvent. |
