What Is Superox-C?
Superox-C is a trademarked extract from Terminalia ferdinandiana, the Kakadu plum native to Australia. This fruit contains the highest natural concentration of vitamin C of any fruit in the world - up to 100 times more than oranges.
The vitamin C in Kakadu plum is exceptionally stable and bioavailable, making it highly effective for topical application. The extract also contains ellagic acid and other polyphenols that enhance its antioxidant properties.
This Australian native ingredient represents the intersection of indigenous knowledge and modern skincare science.
