Verdict Should you buy it?

A US-FDA stick that combines avobenzone, homosalate, octisalate, and octocrylene in a silicone-wax base, with 3-O-ethyl ascorbic acid and panthenol layered in. The clear cast and fragrance-free profile are friendly but the filter set is the older US slate.

Pros
  • Clear silicone matrix avoids the white cast of mineral sticks
  • Fragrance-free and alcohol-free per the INCI
  • 3-O-ethyl ascorbic acid adds an antioxidant note
  • Panthenol and sodium hyaluronate soften the finish
Cons
  • Avobenzone, homosalate, octocrylene set is the older US standard
  • No declared PA rating for UVA depth
  • Wax base can drag over dry skin

Who it's for: A US buyer who wants a clear, fragrance-free stick and is comfortable with the older US chemical filter stack.

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.
Stick
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.
