Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
An extract derived from the leaves or bark of the Machilus japonica tree, a species in the laurel family. It contains flavonoids and other polyphenolic compounds that have antioxidant properties.
How it works
The extract provides antioxidant activity by donating electrons to neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. It may also have mild anti-inflammatory effects, helping to calm redness or sensitivity.
Pros
Gentle antioxidant
Provides free-radical protection without the irritation that some stronger antioxidants can cause, making it suitable for sensitive skin types.
Soothing potential
Early research suggests it may help calm inflammation, which can benefit those with redness or mild irritation.
Cons and cautions
Limited evidence
Most studies are lab-based or on animals; there are few well-controlled human trials proving visible anti-aging or brightening effects.
Rare allergen risk
As a plant extract, it carries a small chance of allergic contact dermatitis, especially for those with tree-related allergies.
Best for
- Anyone looking for a gentle antioxidant boost in their routine
- Those with sensitive or reactive skin who want extra protection
Use caution if
- Individuals with a known allergy to plants in the Lauraceae family (e.g., avocado, cinnamon)
