Zinc Oxide: The Sun’s Worst Enemy (and Your Best Mate)

If you spend your days surfing, fishing, or working under the sun, zinc oxide is a hero you need to know about. Unlike chemical filters that sink into your skin, zinc oxide is a physical blocker - it sits on top of your skin and reflects both UVA and UVB rays. That means long-lasting coverage that’s gentle on your skin and reef-friendly too.

Zinc Percentage and SPF - What You Need to Know

Not all zinc is created equal. The percentage in a formula is a key factor in how much protection you get:

  • 20% Zinc Oxide – Covers the basics, roughly SPF 30–40. Perfect for everyday outdoor fun.

  • 25% Zinc Oxide – Steps up to SPF 50. Ideal for longer days in the sun.

  • 30% Zinc Oxide – Maximum coverage, SPF 50–60+. For hardcore sun warriors who live outdoors.

But here’s the kicker: formulation matters too. Oils, waxes, and other ingredients affect how easy it spreads, how long it stays on, and whether it gives even coverage. A high percentage of zinc won’t do much if it’s hard to rub in.

Why Zinc Oxide Stands Out

  • Broad-spectrum: Blocks UVA & UVB like a pro.

  • Durable: Stays strong in the sun, unlike some chemical sunscreens.

  • Gentle on skin and reefs: Tough on rays, kind to the environment.

Zinc oxide is a reliable, versatile option for anyone spending serious time outdoors. Knowing the percentage helps you pick the right level of coverage for your day in the sun - whether it’s surf, tradie work, or just soaking up the great outdoors.
