Quercus Robur Bark Extract
What is Quercus Robur Bark Extract?
Quercus Robur Bark Extract is derived from the bark of the Quercus robur tree, commonly known as English oak, native to Europe and parts of Asia. This plant-based ingredient is obtained via aqueous or hydroalcoholic extraction, concentrating bioactive polyphenols such as tannins, including ellagitannins and gallotannins. In skincare formulations, it belongs to the category of botanical extracts used mainly in toners, cleansers, and astringents. The tannins interact with skin proteins, producing a protective film that temporarily tightens the surface, refines texture, and balances oiliness. Its polyphenolic content also supports microbial balance on the skin. As a multifunctional agent, it conditions the skin while imparting a matte finish, making it suitable for water-based products where it enhances sensory feel without residue.
