If you saw headlines about Australia's sunscreen SPF test results this year, you probably did what most people did: went and checked the bottle sitting on your bathroom shelf. Spring in Australia means UV levels are climbing again, and the product most of us treat as a set-and-forget step in the routine just had a very public credibility problem.
Here is what the sunscreen SPF test results actually found, what they do not mean for your skin, and what is worth changing about how you buy and apply sunscreen this season, especially if you are also using actives like retinol or vitamin C that make skin more sun-sensitive.
What the testing actually found
In 2025, the consumer group CHOICE sent 20 popular Australian sunscreens to an independent, accredited lab and tested each one against its labelled SPF claim. Sixteen of the twenty did not meet the number on the bottle. Only four performed as advertised.
The most extreme result came from an Ultra Violette product marketed at SPF 50, which tested at SPF 4 in the initial round. CHOICE sent a second, unopened batch to a separate lab in Germany to check the finding, and that result came back at SPF 5. Three sunscreens sold under the Cancer Council brand were also flagged, and one of them, a Cancer Council kids' SPF50+ sunscreen, was recalled. Naked Sundays paused sales of one of its own products while it waited on new testing and guidance from the Therapeutic Goods Administration, and Ultra Violette pulled its Lean Screen product from shelves.
Several of the brands involved disputed the findings and said their own internal testing showed compliance with their SPF claims. That disagreement is part of why the story has not closed out with one tidy list of "safe" and "unsafe" products. SPF testing itself relies on human volunteers and can produce different results between labs, and that variability is now as much a part of the conversation as any single brand.
Why this is landing right as spring starts
September marks the start of spring in the southern hemisphere, and Australian UV exposure climbs quickly from here, well before summer temperatures make it feel urgent. Sunburn and sun damage do not wait for a heatwave, and Australia's skin cancer and melanoma rates are already among the highest in the world. That combination is exactly why a story about SPF claims falling short lands harder here than it would somewhere with a milder sun season. The timing is unfortunate, but it also makes spring a sensible moment to actually rebuild sunscreen habits rather than wait for the review to finish.
Why the regulator got involved
The CHOICE results pushed the Therapeutic Goods Administration to open a public consultation in 2026 titled "Improving the regulation of sunscreens in Australia." The proposals on the table include tighter accreditation for the labs that test SPF, more reliable and transparent testing methods, room for newer testing technologies, and clearer SPF labelling so a claim on a bottle is easier to verify after the fact.
By the middle of 2026, the TGA told a Senate Estimates hearing it had received well over a hundred submissions and was still working through the review, with changes to testing methods flagged as the first priority and any changes to labelling further down the track. This is an active regulatory process, not a finished one, which is worth knowing before you assume this year's headlines are the end of the story.
Why SPF numbers are harder to verify than they look
Part of what made this story land so hard is that most people assume an SPF rating is a fixed, lab-verified fact, like the volume printed on a bottle of milk. In practice, SPF is measured using human volunteers, a set application amount, and a comparison of how long skin takes to redden with and without the product. Small differences in application thickness, skin type, or lab protocol can shift the result, which is part of why two accredited labs can test the same batch and land on different numbers.
A product tested at SPF 4 and sold as SPF 50 has no excuse. The TGA's fix is aimed at tightening the testing and accreditation system itself, not just telling brands to try harder.
What this does not mean for your skin
It is tempting to read "sixteen of twenty failed" and decide sunscreen is not worth bothering with. That is the wrong conclusion. Even the underperforming products in CHOICE's test were still filtering UV to some degree, just less than the label promised. Going without sunscreen remains the bigger risk to Australian skin, not wearing one that tests a few SPF points under its claim.
What the results actually expose is a gap between the number on the front of a bottle and how far you can rely on that number by itself, and that is what changes how you shop and apply sunscreen this year.
Every sunscreen sold in Australia still has to be listed with the TGA before it can legally go on shelves, so there is a baseline of oversight in place even while the testing and accreditation system around SPF claims gets tightened. The CHOICE report is a prompt to shop more carefully within a system that already has that oversight.
How to protect your skin while this gets sorted out
Stop treating the SPF number as the only signal worth checking. Broad-spectrum protection, a texture you will actually reapply without avoiding it, and a brand that responded transparently to the CHOICE findings are all more useful filters than chasing the highest number on the shelf.
Apply more than feels natural, then reapply. Most people put on a thin, uneven layer, which means even a sunscreen that tests exactly at its labelled SPF is under-delivering the moment it goes on too sparingly. Topping up every couple of hours outdoors, and again after swimming or heavy sweating, does more for your actual protection than switching to a different bottle.
The TGA review is still open, so a product that looks fine today could be reassessed later in the process. Checking in on TGA or CHOICE coverage once a season is a more realistic habit than memorising a running list of approved brands.
Retinol, vitamin C, and exfoliating acids all make skin more reactive to UV, which makes spring exactly the wrong season to loosen up on sun protection, whatever is happening with any one brand's test results.
When you do buy something new, the label still tells you plenty even after this year. Look for "broad spectrum" wording, a water resistance rating that matches how you actually use it (swimming, exercise, an ordinary day at a desk), and the AUST L listing number that confirms it is registered with the TGA. None of that guarantees the exact SPF on the front is accurate, but it rules out the products with the least oversight behind them, and it is a better use of your attention at the shelf than reading five different brand marketing claims against each other.
Where antioxidants fit in, and where they do not
Sunscreen is still the frontline defence here, and nothing above changes that. A vitamin C serum worn underneath sunscreen adds a different kind of protection: it helps the skin manage the free radical damage that UV exposure causes at a cellular level, work that sits alongside what a sunscreen's UV filters do. Lustelle's Plump & Glow Serum combines vitamin C with niacinamide and hyaluronic acid, and applying it in the morning before sunscreen adds that antioxidant layer as one companion step in a routine where sunscreen still does the UV filtering.
Two habits worth fixing this spring
The biggest gap is rarely which brand sits on the shelf. It is how much product goes on and how often it gets topped up. Most people apply a thin, patchy layer once in the morning and do not think about it again until they notice they are pink. Fixing that single habit protects your skin more reliably than swapping brands ever will, and it costs nothing.
The second habit is easy to forget: ears, neck, hands, and the part of the scalp visible through hair are the areas people skip most often, and they are just as exposed to spring UV as your face. If your morning routine already includes a vitamin C step for your face, spend the extra ten seconds carrying sunscreen down over your neck and the backs of your hands too. It is a small addition that closes one of the more common coverage gaps, independent of anything the CHOICE report found.
Old sunscreen is worth a second look as well. A bottle that has spent a full summer rattling around in a beach bag or a hot car can lose effectiveness before its printed expiry date, so spring is a reasonable checkpoint to open a fresh one rather than assume last year's leftover is still doing its job at full strength.
The easiest place to start this week is the bottle already in your bathroom: check how old it is, apply more than feels natural, and put it back somewhere you will actually reach for it again at reapplication time rather than only on the way out the door.
