What we found
Based on how this product compares to others in the serums category, cross-referenced against retailer listings and market data.
Strengths
- + Green tangerine extract leads the ingredient list at a genuine 70% concentration, a meaningful inclusion level rather than a trace amount
- + Sustained demand in the Korean market
Worth knowing
- - Brand-reported clinical figures (melanin reduction) are not independently verified
- - Combines multiple brightening actives at once, worth patch-testing if new to actives
- - Contains fragrance via multiple essential oils (lavender, lemon peel, orange peel, bergamot, eucalyptus, ylang-ylang), confirmed across two independent current retailer ingredient listings, despite some marketing implying a cleaner reformulation

Fragrance: this formula contains added fragrance.
| Ingredient | What it is | What it does for skin |
|---|---|---|
| Green tangerine extract (70%) | An extract from unripe (green) tangerines, higher in vitamin C than ripe citrus, at a specified concentration. | Commonly included as a natural vitamin C source for brightening, alongside other pigmentation-targeting actives it's often paired with. |
| Niacinamide | A form of vitamin B3, one of the most studied ingredients in cosmetic dermatology. | Strengthens the skin barrier by boosting ceramide production, helps even out tone by limiting pigment transfer to skin cells, and can reduce the look of enlarged pores. |
| Glutathione | An antioxidant naturally produced by the body, also used topically in some brightening formulas. | Helps neutralize free radicals and is marketed for brightening, though topical absorption and efficacy are less established than oral or injectable use. |
