Most physical uv filter ingredients share a general approach. Zinc Oxide is more targeted than most. Physical barrier scatters UV; anti-inflammatory via zinc ion activity; antimicrobial.
The scientific name is Zinc Oxide. Physical barrier scatters UV; anti-inflammatory via zinc ion activity; antimicrobial. This mechanism is consistent across properly formulated products, which means the real variable is concentration and delivery system.
Typical working concentration is 5–25% (sunscreens); 0.1–2% (skincare). Best suited to all skin types, especially sensitive skin. Primary applications: broad uv protection (uva/uvb), anti-inflammatory, anti-acne.
Works well with: Titanium dioxide, niacinamide.
Best UVA blocker among physical filters; non-irritating; white cast reduced by micronisation.
