01 The score breakdown
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.
No
Formulation & feel
Texture How it feels going on — milk, gel, cream, spray, stick, essence, lotion, powder, or cushion.
Lotion
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.
Yes
Verdict Is it worth it?
Same lotion base as the SPF 30 with homosalate raised to 10%, lifting endocrine-load concerns. Methylisothiazolinone and fragrance remain in the formula, so sensitization risk and ingredient flags are the main trade-offs for the higher SPF figure.
Pros
- Higher labeled SPF for extended outdoor exposure
- Free of denatured alcohol
- Easy-spread, familiar lotion texture
- Tocopheryl acetate adds antioxidant support
Cons
- Homosalate at 10% raises systemic-absorption concern
- Methylisothiazolinone is a potent contact allergen
- Fragrance adds further sensitization risk
- Legacy filter set without modern UVA boosters
Who it's for: Outdoor users prioritizing SPF number over filter modernity who are not reactive to methylisothiazolinone or fragrance.
