Our score 88.3 / 100

10% niacinamide, parfum and octocrylene raise tolerance concerns. Esters, silicones and silica suggest light slip; wear is uncertain, with no specific health concern established.

Invisible No white cast — chemical/hybrid filters that straight-up disappear on skin. South Korea
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.
Chemical
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.
No
Alcohol-free No drying short-chain alcohols (alcohol denat., SD alcohol, ethanol). Doesn't mean fatty alcohols like cetyl or stearyl — those are emollients.
