03 The facts, at a glance
Protection
Filter type Mineral filters (zinc oxide, titanium dioxide) sit on skin and reflect UV. Chemical filters absorb UV. Hybrid runs both.
Hybrid
Broad spectrum Covers both UVA and UVB. UVA drives aging and deeper damage; UVB gives you burns.
Yes
Formulation & feel
Texture How it feels going on — milk, gel, cream, spray, stick, essence, lotion, powder, or cushion.
Essence
Finish How it looks 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' is different — it can hide masking fragrance. Botanical oils still scent.
Yes
Alcohol-free No drying short-chain alcohols (alcohol denat., SD alcohol, ethanol). Doesn't mean fatty alcohols like cetyl or stearyl — those are emollients.
Yes
Verdict Is it worth it?

A Korean hybrid serum stacking zinc oxide, titanium dioxide, BEMT, DHHB, and Uvinul T 150 for full-spectrum coverage without octinoxate. Bergamot oil with disclosed limonene, linalool, and citral pull sensitivity down despite the modern filter slate.

Pros
  • All-modern filter stack covers UVA and UVB without octinoxate
  • PA++++ rating signals high UVA protection
  • Alcohol-free silicone vehicle keeps the feel light
  • Niacinamide and centella support barrier and tone
Cons
  • Bergamot oil is photosensitizing under sun exposure
  • Limonene, linalool, and citral are disclosed allergens
  • Hybrid mineral load can cast a slight whiteness

Who it's for: A Korean-skincare buyer who wants modern non-octinoxate filters and accepts essential-oil sensitizers as part of the finish.
