Verdict Should you buy it?

A lighter serum hybrid with octisalate, bemotrizinol, DHHB, amiloxate, and titanium dioxide, supported by niacinamide, panthenol, and cica. SPF45 PA++ is lower than peer offerings, and added fragrance limits suitability for reactive skin.

Pros
  • Modern DHHB and bemotrizinol filters
  • Niacinamide and panthenol included
  • Cica and madecassoside support calming claims
  • Alcohol-free essence texture
  • No octinoxate or oxybenzone
Cons
  • SPF45 PA++ is lower protection than most peers
  • Added fragrance present in a calming formula
  • Tea tree leaf extract can bother very reactive skin
  • Lighter texture may not last full sun-exposure days

Who it's for: Buyers wanting a lightweight calming SPF for moderate daily exposure; not for high-UV days or fragrance-sensitive skin.

03 At-a-glance facts
Protection
Filter type Mineral filters (zinc oxide, titanium dioxide) sit on skin and reflect UV. Chemical filters absorb UV. Hybrid blends both.
Hybrid
Broad spectrum Protects across both UVA and UVB ranges. UVA causes aging and deeper damage; UVB causes burns.
Yes
Formulation & feel
Texture How the formula feels at application — milk, gel, cream, spray, stick, essence, lotion, powder, or cushion.
Essence
Finish How the formula looks on skin 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' differs — may contain masking fragrance. Botanical oils still scent.
No
Alcohol-free No drying short-chain alcohols (alcohol denat., SD alcohol, ethanol). Does not refer to fatty alcohols like cetyl or stearyl alcohol, which are emollients.
