What is Yuja?
Yuja (yuzu in Japanese) is a sour, tangerine-sized citrus grown in Korea and Japan. Koreans know it best from yuja tea (yujacha). Most of the fruit's vitamin C is in the peel, which is also rich in flavonoids such as hesperidin. In cosmetics, yuja extract is added to brightening products to help skin look livelier and more even. It is not as strong as a pure vitamin C serum, which is why many formulas pair it with niacinamide or vitamin C derivatives.
How it works
The vitamin C and flavonoids in yuja extract act as antioxidants and may slightly reduce melanin production. Over time this helps dullness and dark spots look less visible.
