Verdict Should you buy it?

A chemical SPF 31 PA+++ gel with octinoxate, octocrylene, and DHHB as the only UVA filter. Alcohol sits second on the list and the base adds fragrance, mineral oil, methylparaben, and BHT, leaving thin UVA coverage and an irritation-prone profile.

Pros
  • Lightweight chemical-only gel
  • Includes squalane and sodium hyaluronate
  • DHHB provides some UVA-I support
Cons
  • Alcohol is the second ingredient
  • Contains fragrance and methylparaben
  • Only one dedicated UVA filter at SPF 31
  • Mineral oil and BHT in the base

Who it's for: Tolerant skin that prefers a thin gel for short casual sun exposure and does not mind ethanol or fragrance.

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.
Chemical
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.
Gel
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.
