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.
Chemical
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.
Essence
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.
No
Alcohol-free No drying short-chain alcohols (alcohol denat., SD alcohol, ethanol). Doesn't mean fatty alcohols like cetyl or stearyl — those are emollients.
No
Verdict Is it worth it?

A watery chemical essence built on octinoxate plus three modern boosters (Uvinul T 150, Uvinul A Plus, bemotrizinol) for high SPF and PA++++ coverage. The lightweight, fast-absorbing finish comes at the cost of ethanol high in the list and fragrance, which limit comfort on sensitive skin.

Pros
  • Four-filter system delivers full UVA-UVB coverage at SPF 50+ PA++++
  • Watery essence texture absorbs fast with minimal residue
  • Modern UV boosters Uvinul T 150, A Plus, and bemotrizinol
  • Hyaluronate and glycerin add lightweight hydration
  • Natural, non-tacky finish suitable under makeup
Cons
  • Ethanol second on the INCI can sting or dry sensitive skin
  • Contains fragrance, a common irritant trigger
  • Includes octinoxate, an older UVB filter some buyers avoid
  • BHT present as a synthetic antioxidant

Who it's for: Oily or combination skin in humid climates who want a featherweight, high-SPF daily chemical sunscreen and tolerate alcohol and fragrance.
