Verdict Should you buy it?

A zinc oxide-only baby lotion built on coconut oil, shea and cocoa butters with bisabolol and sodium hyaluronate for soothing slip. The formula is fragrance-free and alcohol-free, but a single mineral filter at SPF 50 means a visible cast on deeper skin tones.

Pros
  • Zinc oxide as the sole filter, simple single-active system
  • Fragrance-free and free of denatured alcohol
  • Shea and cocoa butter plus bisabolol for sensitive skin
  • Sodium hyaluronate adds light hydration
  • Phenoxyethanol/ethylhexylglycerin preservation, no MIT
Cons
  • Zinc oxide alone tends to leave a white cast
  • Heavy butters and waxes may feel rich on oily skin
  • No tint to offset the mineral finish

Who it's for: Parents seeking a simple fragrance-free mineral lotion for fair to medium skin who can tolerate a noticeable mineral finish.

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.
Mineral
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.
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.
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.
