Thuja Orientalis Extract

What is Thuja Orientalis Extract?

Thuja Orientalis Extract comes from the leaves and twigs of Platycladus orientalis, an evergreen conifer tree native to East Asia, also called Chinese arborvitae. This plant-based ingredient contains bioactive elements like flavonoids, tannins, and volatile compounds, making it suitable for skincare products such as toners, lotions, and serums. In formulations, it functions through multiple mechanisms: as an antimicrobial to curb microbe proliferation, an astringent to temporarily constrict skin proteins for a refined feel, an emollient to smooth surface irregularities, a humectant to bind atmospheric moisture, and a skin conditioner to promote softness and flexibility. These properties allow it to contribute to product stability and enhance skin's sensory qualities without heavy residues, fitting well in routines focused on balanced hydration and protection.
