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.
No
Formulation & feel
Texture How it feels going on — milk, gel, cream, spray, stick, essence, lotion, powder, or cushion.
Lotion
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 pared-back mineral lotion built around titanium dioxide with a short, fragrance- and alcohol-free INCI. SPF28 PA+++ keeps protection modest, but the minimalist base is friendly to reactive skin.

Pros
  • Very short INCI minimizes reactivity risk
  • Fragrance-free and ethanol-free
  • Titanium dioxide as the sole UV filter
  • Hydroxyapatite and glycerin for gentle hydration
  • Lotion texture suits daily indoor wear
Cons
  • SPF28 PA+++ is lower than peers at SPF50
  • Titanium-only filter limits UVA breadth
  • Untinted mineral base can leave a light cast

Who it's for: For sensitive or reactive skin needing a minimalist Japanese mineral lotion for daily, lower-exposure use.
