What Is Zinc Oxide?

Zinc oxide is a mineral compound that provides the most comprehensive physical sun protection available. It offers true broad-spectrum coverage, protecting against both UVA (ageing) and UVB (burning) rays across the entire UV spectrum.

Unlike chemical sunscreens that absorb UV rays, zinc oxide creates a physical barrier that reflects and scatters UV radiation away from the skin. This mechanism makes it photostable and less likely to cause skin irritation or allergic reactions.

Beyond sun protection, zinc oxide has soothing and anti-inflammatory properties that make it beneficial for sensitive, acne-prone, and rosacea-affected skin. It can help calm irritation and has mild antimicrobial effects.

Modern micronized and nano zinc oxide formulations significantly reduce white cast while maintaining protective efficacy. For best protection, apply liberally and reapply every 2 hours during sun exposure.
