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.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

emerging

The ingredient may be promising, but claims should be treated more cautiously.

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)

Usage tips

Use in combination with other antioxidants like vitamin C or E for enhanced protection.
Apply in the morning under sunscreen to help defend against daytime environmental stressors.

Safety summary

Generally recognized as safe for topical use in cosmetics at typical concentrations. As with any plant extract, there is a low risk of skin irritation or allergy, especially for those with plant sensitivities.

Research notes
