Quercus Salicina Leaf Extract is derived from the leaves of the Quercus salicina, a species of oak tree belonging to the Fagoideae family. Also known as Japanese Blue Oak, this tree is native to East Asia, particularly Japan and Korea. The extract is rich in various bioactive compounds, including tannins, flavonoids, and phenolic acids, which contribute to its skin-conditioning properties.
Historically, Quercus salicina has been valued in traditional medicine for its anti-inflammatory and antioxidant properties. Its leaves have been used in various folk remedies, which eventually led to its incorporation into modern cosmetic formulations. The transition from traditional use to cosmetic application was driven by scientific research that validated its skin-beneficial properties.
The process of making Quercus Salicina Leaf Extract typically involves harvesting the leaves, followed by drying and grinding them into a fine powder. This powder is then subjected to solvent extraction, where solvents like ethanol or water are used to isolate the beneficial compounds. The resulting extract is filtered, concentrated, and sometimes further purified to ensure it meets cosmetic-grade standards.
