- Use the sunscreen with the highest
possibleSPF. This is currentlySPF50+ in Australia.

be protected, often missing entire areas of our bodies. When too little sunscreen is applied, it reduces the sun protection factor significantly, e.g. SPF30+ may only work as SPF10.
- Ensure that all exposed skin
is thoroughly coveredwith sunscreen.
- If you are in the water, ensure you use a water-resistant variety of sunscreen and re-apply regularly, at least every two-hours.
