Strengths
- + Three-way brightening stack: niacinamide second in the INCI (5%, retailer-stated), turmeric root extract sixth and kojic acid ninth

Worth knowing
- - Kojic acid % is not disclosed
- - Not fragrance-free — contains Chamaecyparis obtusa wood oil, an essential oil
- - Glycolic acid is the last ingredient, so this is not an exfoliating serum
- - Thin, new review base (116 reviews on YesStyle)

| Ingredient | What it is | What it does for skin |
|---|---|---|
| Niacinamide (5% retailer-stated) | A specific active or extract in this formula. | Not yet independently verified against general dermatology sources. |
| Curcuma Longa (Turmeric) Root Extract | A specific active or extract in this formula. | Not yet independently verified against general dermatology sources. |
| Kojic Acid | A specific active or extract in this formula. | Not yet independently verified against general dermatology sources. |
| Thioctic Acid | A specific active or extract in this formula. | Not yet independently verified against general dermatology sources. |
| Adenosine | A compound naturally present in skin cells, used in skincare as an anti-aging active. | Recognized by South Korea's MFDS as a functional anti-wrinkle ingredient at 0.04% concentration, based on clinical studies showing measurable fine-line improvement; a real but modest effect, not a retinoid substitute. |
| Panthenol | Pro-vitamin B5, which converts to pantothenic acid once absorbed into skin. | Hydrates as a humectant, supports wound healing, and has anti-inflammatory, soothing effects on irritated skin. |
| Squalane | A stable, skin-identical oil, usually plant-derived (from olives or sugarcane) in modern formulas. | An emollient that softens skin and helps prevent moisture loss without feeling heavy or greasy. |
| Allantoin | A soothing compound, naturally occurring in some plants and also made synthetically. | Calms irritation and supports skin healing, often paired with other barrier-focused ingredients. |
