Ranks #1514 of 1558 in the current catalogue. Same base as SPF30 with homosalate 10% — higher endocrine load. MI preservative and fragrance are major sensitizers.
Verdict Should you buy 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.

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.
No
Formulation & feel
Texture How the formula feels at application — milk, gel, cream, spray, stick, essence, lotion, powder, or cushion.
Lotion
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.
No
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.
