Kakadu plum is an Australian story: a small green fruit from the Top End that holds the highest recorded natural vitamin C concentration of any food — measured at roughly fifty to one hundred times that of an orange by weight. Aboriginal communities have harvested it for millennia as both food and medicine; the skincare industry arrived considerably later.
How it works
The extract delivers vitamin C in its natural matrix, accompanied by gallic and ellagic acids — two polyphenol antioxidants with their own published records on oxidative stress — plus flavonoids. In a formula it functions as a botanical reinforcement to lab-made vitamin C: the same brightening and antioxidant direction, arriving with a complementary polyphenol escort that pure ascorbic acid lacks.
Why formulators reach for it
Beyond the chemistry, stability: vitamin C in its native fruit matrix, protected by co-occurring antioxidants, degrades more gracefully than the free molecule. And provenance — sustainably wild-harvested Kakadu plum supports Indigenous enterprise in northern Australia, a supply chain worth knowing about.
In formulation
Appears in brightening and antioxidant serums, usually supporting a primary vitamin C. Well tolerated, non-photosensitising, suitable in pregnancy. For Australian skin especially, there is a quiet satisfaction in a world-class active that grows at home.
