The ingredient narratives reshaping clean beauty.
Zinc Oxide
aka zno · non-nano zinc oxide · mineral spf
The mineral SPF backbone — and the only sun filter the FDA classifies as GRASE (generally recognized as safe and effective) without further data, alongside titanium dioxide. Broad-spectrum (UVA1, UVA2, UVB), photostable, low-allergen, and pregnancy-compatible. The 2025 challenge is sensorial: non-nano zinc at protective concentrations leaves a white cast that even tinted formulations struggle to mask on deeper skin tones. Marie Veronique and Tower 28 lead clean SPF innovation.
- broad-spectrum UVA + UVB protection
- photostable — does not degrade or generate ROS in sunlight
- pregnancy- and reef-safe; dermatologist default for sensitive skin
- mineral SPF
- tinted daily SPF
- post-procedure sun protection
- baby and pregnancy SPF
Non-nano (>100 nm) particles for environmental and absorption-concern reasons; coated zinc (silica, dimethicone alternatives) for dispersibility and feel. Effective at 10–25%. Pairs with iron oxides in tinted SPF for visible-light protection.
White cast remains the unsolved formulation problem on deeper skin. Rub-in feel is improving but still trails chemical filters. 'Mineral SPF' that is actually a hybrid (chemical + mineral) should be disclosed.
Strongly trusted — the clean SPF default, with the open caveat about cast.
