What it is
An extract derived from the leaves of Phormium tenax, a flowering plant native to New Zealand. It is rich in antioxidants (flavonoids) and moisturizing polysaccharides.
How it works
The polysaccharides in the extract form a light film on the skin, helping to retain moisture and reduce transepidermal water loss (water escaping from the skin). The flavonoids provide antioxidant protection against free radicals from UV and pollution, while other compounds may help calm inflammation and redness.
Pros
Gentle soothing
Helps calm redness and irritation without harsh chemicals, making it suitable for sensitive skin types.
Antioxidant support
Provides flavonoids that help neutralize free radicals, potentially reducing signs of environmental aging.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use; there are few peer-reviewed human trials confirming its skincare benefits.
Potential allergen
As a plant extract, it may cause allergic reactions in very rare cases, especially in those with plant allergies.
Best for
- People with sensitive or reactive skin
- Those looking for a gentle antioxidant boost
Use caution if
- Individuals with known allergies to Liliaceae or Asphodelaceae plants (rare)
