What it is
An extract derived from the leaves of Tetragonia tetragonoides, a succulent plant native to New Zealand and parts of Asia and Australia. It is rich in flavonoids, polyphenols, and other antioxidant compounds.
How it works
The extract provides antioxidant activity by neutralizing free radicals, which are unstable molecules that can damage skin cells. It may also help reduce inflammation by calming certain skin pathways, and it contributes to overall skin conditioning by providing moisture and nutrients.
Pros
Gentle antioxidant
Provides a mild shield against free radicals without the irritation that some stronger antioxidants can cause, making it suitable for sensitive skin.
Soothing potential
Early research suggests it may help calm redness and irritation, offering a plant-based option for reactive skin types.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use, not large human trials, so its exact benefits in skincare are not fully proven.
Low concentration use
Typically used at low levels (under 2%), so its effects may be subtle and not as dramatic as more potent antioxidants like vitamin C.
Best for
- People with normal to dry skin looking for antioxidant support
- Those with sensitive skin seeking a gentle, soothing ingredient
Use caution if
- Individuals with known allergies to the plant family Aizoaceae (rare)
