Ingredient review
Biota Orientalis Leaf Extract
INCI: BIOTA ORIENTALIS LEAF EXTRACT
A gentle plant extract with antioxidant potential, but research on its cosmetic benefits is still limited.
In plain English
Biota orientalis leaf extract comes from the leaves of a tree also known as Chinese arborvitae. In skincare, it's used mainly for its antioxidant properties, meaning it can help protect your skin from damage caused by environmental stressors like pollution and UV rays. It's considered very gentle and unlikely to cause irritation, making it a nice addition for sensitive skin types. However, most of the evidence for its benefits comes from traditional use and lab studies, not large human trials.

What it is
Biota orientalis leaf extract is a natural ingredient derived from the leaves of the Biota orientalis (also called Platycladus orientalis) tree, native to East Asia. The leaves contain compounds like flavonoids, tannins, and essential oils that are believed to have antioxidant and anti-inflammatory effects.
How it works
In a cosmetic product, the extract works by donating electrons to neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. Its flavonoids may also help calm redness and irritation by reducing inflammatory signals in the skin.
Pros
Gentle antioxidant
Provides antioxidant protection without common irritation, making it suitable for sensitive skin routines.
Soothing potential
Contains flavonoids that may help calm redness and minor inflammation, offering a dual benefit in one ingredient.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use; there are few high-quality human trials confirming its cosmetic benefits.
Allergy risk
As a plant extract, it can cause allergic reactions in people sensitive to tree pollen or conifer plants, though this is rare.
Best for
- Anyone looking for a gentle antioxidant ingredient
- People with sensitive or easily irritated skin
Use caution if
- Individuals with known allergies to conifer trees or related plants
