Quercus Suber Bark Extract
What is Quercus Suber Bark Extract?
Quercus Suber Bark Extract is derived from the thick, outer bark of the cork oak tree (Quercus suber), a resilient species native to the Mediterranean basin. This bark, harvested sustainably for cork production, yields an extract rich in polyphenols, tannins, and suberin-like compounds. In skincare formulations, it serves mainly as a skin conditioning agent and masking ingredient. It works by forming a protective film on the skin's surface to retain moisture and enhance smoothness, while its natural antioxidants help neutralize environmental oxidants. The astringent properties from tannins provide a subtle tightening sensation. Typically incorporated into creams, lotions, serums, and facial masks at low concentrations, it suits products aimed at daily skin maintenance for various skin types.
