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.
Cushion
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.
No
Verdict Is it worth it?

US mineral cushion built on zinc oxide with ethylhexyl methoxycrylene as a stability booster and a silicone-ester base for spreadability. The formula adds denatured alcohol and pine, chamomile, and rosemary oils that the alcohol-free global version avoids.

Pros
  • Single-filter zinc oxide system, no organic UV chemistries
  • Silicone-ester base spreads more easily than typical mineral creams
  • Cushion delivery suits over-makeup touch-ups
  • Calming aloe, allantoin, and dipotassium glycyrrhizate
Cons
  • Contains denatured alcohol, which can dry or sting reactive skin
  • Pine, chamomile, and similar oils raise the sensitivity floor
  • Zinc-only filter can leave a visible cast on deeper tones
  • No PA rating to confirm UVA grading

Who it's for: US shoppers wanting a non-organic-filter cushion and tolerant of denatured alcohol and essential-oil botanicals.
