SPF Testing Explained.
Everything you need to know about how our sunscreen is tested and why you can trust it.

Why We Made This Page

Sunscreen is something you put on your children your own skin and the people you love.
You deserve clear and simple information about how it is tested and what the SPF number really means.


There has been a lot of discussion recently including an ABC article that mentioned zinc sunscreens and lower preliminary test results.
Those tests did not use the official method that regulators rely on for SPF labels in Australia.


This page explains how SPF is actually measured and how our Sunkind formula is validated.

What SPF50 Actually Means

SPF testing is done on real people in a controlled laboratory setting. A small amount of sunscreen is applied to the skin and exposed to measured UV light so the lab can see how much protection it provides.

To legally use SPF50 the test must follow strict rules including:

•  At least 10 people
•  The correct amount of sunscreen is applied
•  A calibrated UV source
•  Checking the skin the next day for redness
•  Strict analysis to calculate the final SPF number

This is the method recognised in Australia and internationally.

What Our Testing Shows

The Sunkind formula was tested by an independent accredited laboratory following the official ISO 24444 method.

The results showed:

•  Average SPF 54.3
•  Label claim SPF50 in line with ISO requirements

This is the same level of testing used by established sunscreen brands and is the method the TGA accepts for validating SPF labels.

Why You Might See Different SPF Numbers Online

You might see posts or news stories retesting sunscreens and reporting lower numbers. Most of these are not full SPF tests.

These screening tests often:

•  Use only 3 to 5 people instead of 10
•  Apply less product than required
•  Do not check zinc film coverage
•  Use different equipment
•  Are not part of the approved ISO method

Because of these limitations these results cannot be used to confirm or dispute an SPF label. Only full ISO testing is accepted for SPF classification in Australia.
