What it is

A natural extract obtained from the flowers of Phormium tenax, also known as New Zealand flax. The extract contains flavonoids and other polyphenolic compounds that act as antioxidants.

How it works

The antioxidant compounds in the extract neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. By doing so, it helps reduce oxidative stress on the skin. Some compounds in the extract may also have anti-inflammatory effects, which can calm redness and irritation.

Cons and cautions
