What it is
A natural extract derived from the flowers and leaves of Metrosideros excelsa, a tree native to New Zealand. It contains polyphenols and flavonoids, which are plant compounds known for their antioxidant activity.
How it works
In a cosmetic product, it works by donating electrons to neutralize free radicals (unstable molecules that can damage skin cells). This helps reduce oxidative stress on the skin, which is linked to premature aging. It may also calm minor irritation due to its anti-inflammatory compounds.
Pros
Gentle antioxidant
Provides a mild antioxidant boost without common irritation, making it suitable for sensitive skin types.
Natural origin
Derived from a sustainably harvested plant source, appealing to those seeking natural 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 botanical extract, it may cause allergic reactions in people sensitive to related plants, though this is rare.
Best for
- Anyone looking for a gentle antioxidant to add to their routine
- People with normal to combination skin who want extra environmental protection
Use caution if
- Individuals with known allergies to Myrtaceae family plants (e.g., eucalyptus, tea tree)
