Ingredient review
Korean Rowan Leaf Extract
INCI: SORBUS ALNIFOLIA LEAF/STEM EXTRACT
A gentle, plant-derived antioxidant that may help calm skin and defend against environmental stress, though research is still early.
In plain English
This is an extract from the leaves and stems of a tree called Korean rowan (Sorbus alnifolia). In skincare, it's used as an antioxidant—meaning it helps protect your skin from damage caused by things like pollution and UV rays. It also has some soothing properties, so it may help calm redness or irritation. Because it's a natural extract, its effects can vary depending on how it's processed and formulated in a product.

What it is
A botanical extract derived from the leaves and stems of Sorbus alnifolia, a tree native to East Asia. It contains flavonoids and phenolic compounds that act as antioxidants.
How it works
The extract donates electrons to neutralize free radicals (unstable molecules that can damage skin cells), thereby reducing oxidative stress. It may also inhibit certain inflammatory pathways, helping to soothe irritated skin.
Pros
Gentle antioxidant
Provides a mild shield against free radicals without irritating most skin types, making it suitable for daily use.
Soothing potential
Early research suggests it may help calm redness, which is a plus for sensitive or reactive skin.
Cons and cautions
Limited research
Most evidence comes from lab studies, not large human trials, so its real-world benefits are not fully confirmed.
Variable potency
As a natural extract, its active compound levels depend on growing conditions and processing, leading to inconsistent results between products.
Best for
- Anyone looking for extra antioxidant protection in their routine
- People with normal to oily skin who want a lightweight, non-greasy ingredient
