SPF 40 · PA++++
Our score 79.8 / 100

Fragrance-free; octocrylene and chamomile add modest allergy potential. Humectants, silica and polymer support a gel-like feel; makeup compatibility is untested and health screening remains baseline.

Invisible No white cast — chemical/hybrid filters that straight-up disappear on skin. Taiwan
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.
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.
