Sun Zapper Zinc Sticks and Sunscreens are 100% Australian made and have been tested to meet the harsh conditions of our sun, snow, wind and waters. Zinc oxide is a natural sun blocker that stays on your skin for hours when in the water and is a prominent ingredient in our range. It won't burn your eyes and is great for people with sensitive skin conditions. Proud to say the Sun Zapper suncare range is also nano-particle free and not tested on animals!
