The native Australian fruit with the world's highest natural concentration of vitamin C. Brightens. Antioxidant-protects. Gentle enough for sensitive skin.

What it is.

Kakadu plum grows wild in the savannah woodlands of northern Australia. For tens of thousands of years it has been a food and medicine plant for the Indigenous communities of the region.

It contains up to 100 times more vitamin C than oranges. By weight, no other natural source comes close.

In skincare, this matters because vitamin C is one of the most clinically proven actives for brightness, tone, and antioxidant protection — but synthetic vitamin C (L-ascorbic acid) is famously unstable and often irritating. Kakadu plum delivers the same benefits in a form skin actually tolerates.

What it does.

Brightens and evens tone

Vitamin C interrupts the production of excess melanin, reducing the appearance of pigmentation, sun spots, and post-inflammatory marks. Consistent use brings tone into balance.

Antioxidant protection

Environmental stressors — UV, pollution, blue light — generate free radicals that age skin prematurely. Kakadu plum's antioxidant load neutralises them.

Supports collagen

Vitamin C is a cofactor in collagen synthesis. Without it, your skin literally cannot make the collagen it needs for firmness and elasticity.

Gentle on sensitive skin

Unlike synthetic ascorbic acid, which can sting and irritate, Kakadu plum's vitamin C is delivered in a botanical matrix with co-occurring polyphenols that buffer and soothe.

Who it's for.

Dull, uneven, or pigmented skin. Sensitive skin that hasn't tolerated L-ascorbic acid. Mature skin seeking visible brightness. Anyone living with sun exposure or environmental stress — which is most of us.
