Quercus Salicina Stem Extract is derived from the stems of Quercus salicina, a species belonging to the Fagoideae family. The extract is rich in various bioactive compounds, including tannins, flavonoids, and phenolic acids, which contribute to its multiple beneficial properties.
Historically, Quercus salicina has been utilized in traditional medicine across East Asia, particularly in Japan and Korea, for its purported health benefits. Its journey into the cosmetic industry is relatively recent, driven by the growing demand for natural and plant-based ingredients. Researchers and formulators have recognized its potential, leading to its incorporation into a variety of skincare and haircare products.
The extraction process typically involves harvesting the stems of Quercus salicina, followed by drying and grinding them into a fine powder. This powder is then subjected to a solvent extraction process, often using water or alcohol, to isolate the desired bioactive compounds. The resulting extract is filtered, concentrated, and sometimes further refined to ensure purity and efficacy before being added to cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Quercus Salicina Stem Extract:
Quercus Salicina Stem Extract has antimicrobial properties, meaning it can help inhibit the growth of bacteria and other microorganisms on the skin.
