Verdict Should you buy it?

A Korean tone-up hybrid serum carrying the same modern filter slate as the Airy Sun Serum, with extra titanium dioxide for a brightening cast. Bergamot oil and disclosed limonene, linalool, and citral keep sensitivity headroom modest.

Pros
  • All-modern filter stack covers UVA and UVB without octinoxate
  • PA++++ rating signals high UVA protection
  • Tone-up TiO2 gives a soft brightening finish
  • Niacinamide and centella support barrier health
Cons
  • Bergamot oil is photosensitizing under sun exposure
  • Limonene, linalool, and citral are disclosed allergens
  • Tone-up TiO2 risks visible cast on deeper skin

Who it's for: A Korean-skincare buyer who wants a tone-up finish with non-octinoxate filters and accepts essential-oil sensitizers.

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.
Yes
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.
