Citrus Unshiu (Satsuma mandarin) peel powder is a plant-derived ingredient rich in flavonoids (such as hesperidin and nobiletin) and vitamin C, used in skincare for antioxidant and brightening-supportive properties. It is typically incorporated as a botanical extract for conditioning and free-radical-scavenging effects.
