Verdict Should you buy it?
A gel with octinoxate and Uvinul A Plus reaching SPF 45 PA+++, layered with arbutin, dipotassium glycyrrhizate, and a dense botanical blend. Citrus peel oil combined with octinoxate raises the irritation risk for reactive skin.
Pros
- Alcohol-free with no added parfum or fragrance
- Uvinul A Plus adds modern UVA-1 coverage
- Dipotassium glycyrrhizate and aloe for soothing
- Alpha-arbutin for brightening support
- Silica gives a smooth, semi-matte feel
Cons
- Contains citrus peel oil, a known sensitizer
- Octinoxate is a dated UVB filter
- Dense botanical and extract blend raises irritation risk
Who it's for: Suits non-reactive skin wanting a brightening-focused daily gel; skip if you react to essential oils or prefer octinoxate-free formulas.

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.
Gel
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.
