Sunscreen is a crucial part of protecting our skin from sun damage, but with so many options available, choosing the right one can be overwhelming. To ensure that sunscreens live up to their SPF claims, rigorous testing is essential.

Where the sunscreens were tested

While we conduct many product tests in-house, we sent 20 sunscreens to an external laboratory in Sydney accredited to test sunscreens according to the Australian/New Zealand Sunscreen Standard. This lab has the expertise and equipment necessary for SPF testing to determine which sunscreens provide the best protection.

How we choose which sunscreens to test

Our selection process involved retail data, buying behavior expertise, and consumer trends to choose a variety of sunscreens available in Australia. We aimed to include popular brands, different price points, and products suitable for various demographics, including kids.

How we test sunscreens

Sunscreen testing is done to verify if manufacturers meet their SPF claims according to the Australian/New Zealand Sunscreen Standard. The testing process involves a panel of volunteers with specific skin types and follows a strict protocol of product application, solar simulation, and result reading.

Product application

• Precise measurement of sunscreen applied
• Even application and drying

Solar simulation

• Calibrated solar simulator mimicking sunlight spectrum
• Incremental light doses applied to test areas

Reading of results

• Results recorded after 24 hours
• UV exposure needed for burning determined

Why are sunscreen testing results variable?

Testing results can vary between labs, which can impact SPF ratings. CHOICE applies a 20% allowance to account for this variability. Despite this, many sunscreens still did not meet their SPF claims, indicating a potential issue in the Australian sunscreen market.

Scoring criteria explained

The CHOICE Expert Rating is based on the measured SPF compared to the label claim, with a pass result at 80% or higher. A score of 100% indicates that the product meets its claimed SPF.
