70% green tangerine extract (stable vitamin C) + niacinamide targets pigmentation through dual tyrosinase inhibition pathways.
Goodal Green Tangerine Vitamin C Dark Spot Serum combines 70% green tangerine extract (a stable vitamin C source) with niacinamide and adenosine for synergistic tyrosinase inhibition — targeting hyperpigmentation through both the vitamin C inhibition pathway and the niacinamide melanin-transfer inhibition pathway simultaneously. The fermented formulation improves compatibility for sensitive skin. At $30 for 30 mL, it's the mid-range choice that delivers a multi-ingredient approach to pigmentation that pure niacinamide products cannot. Honest weakness: green tangerine vitamin C has less peer-review data than L-ascorbic acid, and the combination formula makes it harder to isolate which ingredient is producing the brightening result.
Pros
- Vitamin C + niacinamide combination targets pigmentation through two pathways
- Green tangerine vitamin C is more stable than L-ascorbic acid
- Fermented formulation for improved skin compatibility
- Lightweight serum texture suits all skin types
Cons
- Less peer-reviewed evidence for green tangerine vitamin C vs standard L-ascorbic acid
- Combined formula makes results attribution to individual actives difficult
