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 US-market reformulation pairs zinc oxide with a silicone-heavy elegance system and a birch-juice hydration story. It avoids fragrance and alcohol but includes essential oils, which carry mild sensitization risk.

Pros
  • Zinc oxide as the sole UV filter for broad-spectrum coverage
  • Silicone system improves spread and finish for a mineral
  • Birch juice, hyaluronic acid, and panthenol for hydration
  • No fragrance or denatured alcohol per the INCI
Cons
  • Chamomile and pine essential oils may sensitize reactive skin
  • Single-filter mineral typical of US FDA constraints
  • No PA rating disclosed for the US version
  • Tone-up finish may read pale on deeper tones

Who it's for: US buyers who want a mineral sunscreen with a smoother silicone feel and don't react to chamomile or pine oils.
