Kakadu plum is an Australian fruit that is a very rich source of Vitamin C. This vitamin can be useful to clear pimple-causing bacteria on the face. It can be mixed with clay to soothe the skin and flush off the impurities for an even complexion.
So, what exactly is kakadu plum? "It's a fruit grown in northern Australia that's rich in Vitamin C " says Joshua Zeichner, an assistant professor of dermatology at Mount Sinai Hospital in New York City. "It's been shown to fight off cancer cells and may be helpful for UV-damaged skin," he adds. Though Zeichner stresses that there hasn't been much research on the efficacy of the ingredient yet, data from Food Chemistry and the U.S. Department of Agriculture suggests that kakadu plum contains 55 times more vitamin C than a Florida orange. In addition to brightening and protecting skin, "it might provide some Free Radical protection to make the scalp healthier and benefit your hair," says cosmetic chemists.
