Verdict Should you buy it?

A polished hybrid serum combining tranexamic acid, niacinamide, ergothioneine, and a modern filter blend of zinc oxide, bemotrizinol, Uvinul A Plus, octinoxate, and titanium dioxide. Filter modernity and texture are strong points; ethanol, fragrance, sulfite, and octinoxate are the trade-offs.

Pros
  • Tranexamic acid and niacinamide lead the active list
  • DHHB (Uvinul A Plus) and BEMT add modern UVA defense
  • Ergothioneine and Centella extract layer in antioxidants
  • Serum texture feels light and breathable on application
  • Multiple botanical ferments and extracts in the matrix
Cons
  • Ethanol sits in the upper portion of the INCI
  • Fragrance present alongside synthetic dyes Blue 1 and Acid Red 52
  • Sodium metabisulfite is a known sulfite allergen
  • Octinoxate remains in the filter mix

Who it's for: Buyers wanting a skincare-leaning daytime serum with brightening actives, who tolerate alcohol and fragrance.

03 At-a-glance facts
Protection
Filter type Mineral filters (zinc oxide, titanium dioxide) sit on skin and reflect UV. Chemical filters absorb UV. Hybrid blends both.
Hybrid
Broad spectrum Protects across both UVA and UVB ranges. UVA causes aging and deeper damage; UVB causes burns.
Yes
Formulation & feel
Texture How the formula feels at application — milk, gel, cream, spray, stick, essence, lotion, powder, or cushion.
Essence
Finish How the formula looks on skin once dry: matte, natural, dewy, or glowy.
Natural
Tinted Adds sheer pigment (iron oxides) that masks the white cast common to mineral filters and gives a skin-tone finish.
No
Fragrance-free No synthetic perfume added. Not FDA-defined in the US; the EU requires 'Parfum' + the 26 named allergens on the label. 'Unscented' differs — may contain masking fragrance. Botanical oils still scent.
No
Alcohol-free No drying short-chain alcohols (alcohol denat., SD alcohol, ethanol). Does not refer to fatty alcohols like cetyl or stearyl alcohol, which are emollients.
No
