Vitamin C botanical extract
Green Tangerine
INCI: Citrus Nobilis (Tangerine) Peel Extract·Limited evidence
An extract of unripe green tangerine, a Jeju-grown citrus naturally high in vitamin C and flavonoids, used in K-beauty vita C dark-spot serums. It is a whole-fruit botanical source of vitamin C, not a purified or stabilised ascorbic acid, so it behaves gently and its evidence is thinner than a true vitamin C serum.
Studied for
- ·The appearance of a brighter, more even-looking tone
- ·The look of reduced dark spots
- ·Radiance and antioxidant support
How it’s thought to work
Green tangerine supplies vitamin C, hesperidin and other citrus flavonoids as part of a whole-fruit extract. It is studied for antioxidant and brightening-appearance support, but because the vitamin C is not isolated or stabilised, its strength and stability are not comparable to a dosed L-ascorbic acid or a purified derivative.
Questions
- Is green tangerine the same as a vitamin C serum?
- Not really. It is a natural source of vitamin C, but the vitamin is not isolated or stabilised the way it is in an L-ascorbic acid or a THD ascorbate serum, so it is gentler, less concentrated and less proven. Treat it as a pleasant brightening botanical, not a substitute for a dosed vitamin C.
- Why do these serums add niacinamide and arbutin?
- Because those two are usually the actives doing the measurable tone work. In most green tangerine serums the disclosed niacinamide and alpha arbutin are the real engine, with the citrus extract adding a glow-and-antioxidant halo on top.
- Is green tangerine extract safe to use with retinoids or acids?
- Generally yes. It behaves as a gentle antioxidant botanical rather than an exfoliant, so it is commonly layered into routines alongside retinoids or acids without the same spacing precautions that stronger vitamin C derivatives sometimes need.
