Ingredient review
Korean Rowan Branch/Leaf Extract
INCI: SORBUS ALNIFOLIA BRANCH/LEAF EXTRACT
A gentle plant extract with antioxidant potential, but research on its specific benefits in skincare is still limited.
In plain English
This is an extract made from the branches and leaves of the Korean rowan tree (Sorbus alnifolia). In skincare, it's used mainly for its antioxidant properties, which means it can help protect your skin from damage caused by environmental stressors like pollution and UV rays. It's considered a mild, soothing ingredient, but because it's not as widely studied as some other plant extracts, its exact benefits are less certain.

What it is
A natural extract derived from the branches and leaves of Sorbus alnifolia, a tree native to East Asia. It contains various plant compounds like flavonoids and phenolic acids that have antioxidant activity.
How it works
The extract works by donating electrons to neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. This antioxidant action helps reduce oxidative stress on the skin, potentially calming inflammation and supporting the skin's natural repair processes.
Pros
Gentle antioxidant
Provides a mild antioxidant boost without common irritation, making it suitable for sensitive skin types.
Natural origin
Derived from a plant source, appealing to those who prefer naturally-sourced skincare ingredients.
Cons and cautions
Limited research
Most evidence comes from lab studies, not human clinical trials, so its real-world benefits are not fully proven.
Potential allergen
As a plant extract, it can cause allergic reactions in people sensitive to related botanical families.
Best for
- People looking for a gentle, natural antioxidant ingredient
- Those with normal to dry skin who want extra environmental protection
Use caution if
- Individuals with known allergies to Rosaceae family plants (e.g., apples, pears, roses)
