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.
Mineral
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.
Cream
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?

The global version leads with zinc oxide and butyloctyl salicylate as a solvent booster, paired with birch juice, hyaluronic acid, and saccharomyces ferment for hydration. Clean and fragrance-free, with the typical chalkiness of a mineral cream.

Pros
  • Zinc oxide for broad-spectrum mineral coverage
  • Butyloctyl salicylate improves filter solubility and feel
  • Birch juice, hyaluronic acid, and ferment for hydration
  • Fragrance-free and alcohol-free per the INCI
  • PA++++ for strong UVA rating
Cons
  • Mineral cream can leave a chalky finish on deeper tones
  • Chamomile and pine essential oils may sensitize reactive skin
  • Silicone-heavy base may not suit those avoiding dimethicones

Who it's for: Buyers who prefer a zinc-based mineral cream with hydration support and tolerate trace essential oils.
