In Japan, Goji berry (Kuko no mi) has been used since ancient times for its immunity-boosting, liver-strengthening, anti-aging properties. The young stems and leaves are edible and can be used in tempura, ohitashi, goma-ae, or cooked with rice. The red berries are dried and consumed as medicinal food.
Goji Berry extract contains a variety of antioxidants like polysaccharides, flavonoids and even vitamin C which are all strong antioxidants. They collectively help to enhance the antioxidant property of the extract, reducing oxidative stress on the skin and preventing free radicals from damaging the skin cells. This helps to maintain healthy skin cells and give skin a youthful appearance. Goji Berry extract also contains fatty acids which help to provide the skin with hydration and a strong barrier.
