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?

A pure mineral SPF built on zinc oxide and titanium dioxide in a silicone-and-PEG base. Filter choices are clean, but imidazolidinyl urea — a formaldehyde-releasing preservative — and likely white cast hold the formula back.

Pros
  • 100% mineral filter system with zinc oxide and TiO2
  • Fragrance-free and alcohol-free
  • Ascorbyl tetraisopalmitate adds stable vitamin C
  • Lightweight silicones aid blendability for a mineral
Cons
  • Imidazolidinyl urea releases formaldehyde over time
  • Mineral filter density risks visible cast on deeper skin
  • PEG and silicone load may feel heavy on oily skin

Who it's for: Mineral-only seekers on lighter skin tones who tolerate formaldehyde-releasing preservatives and want stable vitamin C added in.
