Verdict Should you buy it?

An essence-textured chemical SPF using a five-filter modern EU stack (Uvinul T 150, Mexoryl SX and XL, Bemotrizinol, DHHB) in a clean fragrance-free, alcohol-free base with ectoin and niacinamide. Few sunscreens in this catalog combine this filter system with this base.

Pros
  • Five-filter modern EU stack with no octinoxate or homosalate
  • Fragrance-free and alcohol-free
  • Ectoin and niacinamide support hydration and tolerance
  • Lightweight essence texture with adenosine and tocopherol
  • Botanical extracts kept to soothing, low-risk choices
Cons
  • Chemical-only system may not suit those preferring mineral filters
  • Polymer-rich formula may pill under heavy makeup
  • No tint, so no built-in tone correction

Who it's for: Sensitive and acne-prone users wanting an essence-light, fragrance-free chemical SPF with a current EU filter system.

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.
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.
Yes
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.
