Kakadu plum (Terminalia ferdinandiana) is an Australian fruit extract best known for its exceptionally high vitamin C and polyphenol content.

In skincare it is mainly used for its antioxidant and skin-brightening effect.

It also contains gallic acid, ellagic acid and related phenolics, which add to its antioxidant activity.

The vitamin C component can support collagen synthesis and is therefore attractive in anti-ageing, photodamage and dull-skin formulations.
