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.
Stick
Finish How it looks once dry: matte, natural, dewy, or glowy.
Matte
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?

A wax-based stick using homosalate, octocrylene, octisalate, and avobenzone rather than modern EU filters. The format is fragrance-free and alcohol-free, but the organic filter load is heavy and older-generation.

Pros
  • Fragrance-free and free of denatured alcohol
  • Panthenol and tocopherol added as soothers
  • Portable matte stick for reapplication
  • Silica and silicones blur and mattify
Cons
  • Heavy load of legacy organic UV filters
  • UVA depends on avobenzone, not modern long-UVA filters
  • Waxy base can drag and leave residue
  • Lower filter-modernity than the brand's cream/serum

Who it's for: NIDA fans wanting a portable matte stick for reapplication who accept legacy filters in exchange for the format.
