Citrus Tangerina (Tangerine) Extract

Citrus Tangerina (Tangerine) Extract is derived from the fruit and peel of the tangerine (mandarin orange, Citrus tangerina). It is notable for its polymethoxylated flavones — nobiletin and tangeretin — which are potent antioxidants with additional anti-inflammatory activity. The extract also provides hesperidin (a citrus bioflavonoid), carotenoids, and vitamin C precursors. Used as the headline active in Korean 'Vita C' skincare formulas (notably Goodal's Green Tangerine line) for antioxidant protection and skin brightening.
