Have you ever been burnt while wearing sunscreen?

Many people get caught out because they don’t slop enough on to start with or forget to re-apply every two hours. Research shows 85% of Aussies don’t apply enough sunscreen.

For maximum protection, apply SPF30 (or higher) broad spectrum, water-resistant sunscreen to any exposed skin. No sunscreen blocks out 100% of UV radiation so sunscreen should be used as the last line of defence after clothing, a broad-brim hat, sunglasses and shade. Apply 20 minutes before going outside and reapply every two hours (or more frequently if swimming or sweating). Use the sunscreen calculator to find out how much you need to apply.

The calculator is also a function on the free SunSmart app.
