Quercus (Oak) Root Extract
What is Quercus (Oak) Root Extract?
Quercus (Oak) Root Extract is obtained from the roots of oak trees belonging to the Quercus genus, which are deciduous trees found in temperate zones across Europe, Asia, and North America. Botanically, it is valued for its high content of tannins, polyphenols, and flavonoids, natural compounds extracted through water or solvent methods. In cosmetics, it falls under skin conditioning and astringent categories, commonly featured in toners, cleansers, serums, and hair care products. Functionally, the tannins create a subtle tightening effect on the skin surface by binding to proteins, aiding in pore refinement and oil control, while antioxidants combat environmental oxidative stress. This makes it a staple in natural formulations seeking gentle, plant-derived performance without synthetic additives.
