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.
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.
Yes
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?

A tinted mineral serum using zinc oxide as the sole UV filter with allantoin, bisabolol, niacinamide, and a polyglyceryl-based emulsion system. The formula is light on flag ingredients and delivers solid coverage for a single-filter zinc.

Pros
  • Zinc oxide as the sole UV filter, no chemical filters present
  • Fragrance-free with no PEGs or denatured alcohol in the INCI
  • Niacinamide, bisabolol, and allantoin support sensitive skin
  • Iron oxide tint helps offset mineral cast
  • PA++++ rating for strong UVA coverage
Cons
  • Single-filter zinc system may feel heavy on some skin
  • Tint payload limited to a single shade range

Who it's for: Suits sensitive or reactive skin wanting a tinted zinc-only mineral with a clean preservative and emollient system.
