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.
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?

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.
