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.
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?

All-mineral zinc oxide SPF in a tinted, ester-rich base with ectoin and hydroxyectoin for hydration. Iron oxides and an elegant oil phase blunt the mineral cast, but lavender and orange peel oils are the main sensitivity flag in an otherwise clean formula.

Pros
  • Single-filter zinc oxide, fragrance-free
  • Ectoin and hydroxyectoin support hydration
  • Iron oxides reduce visible mineral cast
  • Tocopherol antioxidant included
  • Lightweight ester base for cosmetic feel
Cons
  • Lavender and orange peel oils may irritate reactive skin
  • Mineral load can leave a faint cast on deeper tones
  • Polyhydroxystearic coating may feel heavy in humid weather

Who it's for: Mineral-SPF buyers who tolerate essential oils and want a tinted, hydrating daily face sunscreen with skincare actives.
