. But she still hears doubts about them.
It’s a hot topic for content creators too. Australian YouTuber Hannah Price’s year-long “backyard” testing comparing Australian and Japanese sunscreens earned more than 2.5 million views.
“Growing up in Australia, I hated sunscreen,” Price said in the video. “And then when I moved to Japan, I discovered Asian skincare and very quickly realised that actually, I didn’t hate all sunscreen; I just hated Australian sunscreen. But anytime I’d recommend it to someone, I kept hearing that Asian sunscreen isn’t strong enough for the Australian sun.”

Australian cosmetic chemist Michelle Wong, who breaks down complex beauty-related science in her posts and videos, told RNZ their lightweight texture makes them more practical for integrating in daily life than the thicker sunscreens we’re used to slathering on for sporadic beach trips.
But she notes local brands probably design products for how Australians and New Zealanders typically use them — to suit our outdoor summer lifestyle.
“If an Australian brand brings out a sunscreen that’s super lightweight and rubs off easily … chances are people are going to buy it and then burn and then complain.”

NZ Dermatology Society spokesperson AJ Seine says another appeal is they use more advanced UV filters which sit nicely on the skin, but he’d like to see more research on them. He adds consumers should remember that sun-avoidance habits in places like Korea and Japan don’t mirror New Zealand’s love of the outdoors.
Do they protect us just as well?
A Korean sunscreen’s package in Farmers shows an additional sticker applied that says “broad spectrum, very high protection”.

All sunscreens sold in Aotearoa (imported or local) must comply with the Australian/New Zealand standard (A/NZS) , which aligns closely with international ISO testing and includes ‘broad spectrum’ labelling requirements.
Our standard defines “broad spectrum” as having at least a third of the SPF dedicated to UVA protection . Japanese and Korean sunscreens use a different system — SPF for UVB and PA+ for UVA — but both countries still require testing for pre-market approval (depending on categorisation), with Korea recognising international standards including A/NZS and ISO .
Consumer NZ researcher and writer Belinda Castles says it can be a challenge for shoppers to know which standard imported products are actually tested to unless brands and retailers are transparent.
“There’s no register of sunscreens in New Zealand, and that’s one of the reasons we’d like sunscreens regulated as a therapeutic product … at the moment, [retailers are] supposed to comply [with ensuring it meets the A/NZS], but there’s no monitoring of it.”
Korean sunscreen products sold at another store show the original packaging which shows the SPF and PA value, without ‘broad spectrum’ labelling.

Unlike Australia, New Zealand doesn’t have a public online database listing sunscreens that have passed checks and are registered for sale. Australian lawyer-turned-entrepreneur Lauren Lee writes these strict Therapeutic Goods Administration (TGA) rules, including only allowing certain UV filters, is why major retailers there usually can’t stock Korean sunscreens.
Castles’ review of some imported products also found some labelling inconsistencies against the standard. Still, Bhikoo notes that packaging has improved from when she first started buying them, with some brands now including English labelling as Western demand grows.

What about water resistance?
Our standards require the labelled SPF to hold up after immersion, with limits on water-resistance claims. Korean and Japanese labels may indicate 40- or 80-minute durability if the product maintains at least half its original SPF after 20-minute increments of being in water.
Japan’s JCIA uses a voluntary sunscreen standard based on international ISO rules, but it still encourages all brands to follow it so consumers can feel confident in what they buy.
Japan’s sunscreen water resistance rating system is indicated with “Water Resistant” or “Super Water Resistant” with symbols and one or two-star symbol for immersion times (40/80 mins).

But Wong cautions that the lightweight products going viral online were never designed for physical activity outdoors.
“I think one of the mistakes I do see people in Australia and other Western countries doing is buying Korean sunscreens and then using them like they would any other Western sunscreen,” she says. “There are sunscreens in Korea that are designed for that, and they are not the ones that are popular overseas.”
Have there been known issues?
Confidence in Asian sunscreens wavered several years ago when ingredient-database INCIDecoder published lab results showing a Korean product falling short of its SPF claim. Additional findings of more failed sunscreen SPF claims surfaced through a Korean Dermatological Association video .
However, testing wasn’t the only issue here. In another video , Odile Monod, a Korean-based beauty marketer with more than 15 years’ experience who often translates related information and news, said a legal loophole meant companies could resubmit slightly tweaked formulas without needing to retest for SPF.

Consumer NZ’s latest report highlights a broader issue here: no requirement for regular testing. Thirteen products of 169 on their updated database (which doesn’t include Asian sunscreens) were last tested a decade or more ago, while 43 didn’t provide that information.
Several brands also had used a lab which has now been embroiled in controversy . But Castles says some of them told Consumer NZ they would be retesting in a different lab.
It’s worthwhile noting sunscreen tests can produce varied results — equipment, skin type, application and human subjectivity in analysing results can all play a role, Wong says. Even the TGA acknowledges this variability .
So how should you choose?
There’s no fool-proof way to know a sunscreen truly performs — even an expert like Wong says so. But she says it’s important to keep the basics in mind and always use sun protection. She personally reserves the Korean sunscreens for light casual wear and uses the Australian ones when hitting the beach or spending long hours outdoors.

Bhikoo says if these Asian sunscreens get you into the habit of using sun protection more often then that’s encouraging.
Castles recommends looking for products that explicitly state they comply with A/NZS and asking retailers for evidence when in doubt. Wong adds that proper storage during shipping matters too; extreme temperatures can compromise formulas.
If you want to go deeper, Monod notes that Korean sunscreens labelled as “functional cosmetics” are the category that undergo regulated SPF testing, and packaging must list the manufacturer and distributor — details that may help you trace product quality.
By translating the Korean on the sunscreen bottles, people can find out more information, such as if it’s described as a “functional cosmetic” and the name of the manufacturer and distributor.

Find reputable retailers, Bhikoo advises. Some may even show proof of the completed lab testing online, such as where and when it was tested.
And remember, sunscreen is only one part of protection. Seek shade, wear protective clothing — and use common sense about whether your sunscreen is keeping up with your lifestyle.
