UV protection How hard it blocks UVA + UVB across the spectrum at the stated SPF/PA. 82
Filter modernity Dings legacy filters (octinoxate, oxybenzone); rewards photostable next-gen ones. 80

Reef / env. safety Reef toxicity plus how biodegradable the UV filters and surfactants are. 100
Cosmetic elegance Spread, finish, white-cast, and how it actually feels on skin. 74

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?

A zinc-only mineral tinted in a silicone-blur base with niacinamide, squalane, and bisabolol. Fragrance-free and broadly benign, with tint offsetting the typical mineral white cast.

Pros
  • Single-filter zinc oxide system, no chemical filters
  • Fragrance-free formulation
  • Niacinamide and bisabolol support a calm base
  • Iron oxide tint reduces mineral white cast
  • Silicone-blur finish smooths skin texture
Cons
  • No declared PA rating on this US listing
  • Silicone- and PEG-heavy base may not suit all preferences
  • Tint shade range limits deeper skin tones
  • Zinc-only filter can feel heavier than modern hybrids

Who it's for: Sensitive or reactive skin wanting a fragrance-free mineral SPF with a blurring, tinted finish in a light-to-medium range.
