Lab Muffin beauty scientist slams viral sunscreen toast test as a complete lie
An Australian scientist has labeled the viral ‘sunscreen toast test’ a complete lie and wondered why anyone would want to put skin care on bread anyway.
The test claims to show how well a particular brand of sunscreen works by spreading it on half a piece of bread before placing it in the toaster.
When it comes out, the side with the sunscreen is still white and doughy, while the side without is golden brown.
But the video is based on a clever lie, Michelle Wong, a qualified cosmetic scientist and doctorate in organic medicinal chemistry, explained in a video about her Lab Muffin Beauty Science Instagram.

The 34-year-old claims the video simply proves that “beauty standards have gotten out of hand.”
‘This just shows that water absorbs heat. Browning bread is the Maillard reaction. It uses heat, water is great at absorbing heat.
“This would work with a moisturizer.”
Michelle posted the short clip on Tuesday with a cheeky question about why we are texture shaming bread.
And others agreed that the toast video, and skincare food videos in general, are “ridiculous.”
“This is worse than the vitamin C serum on apple slices,” said one woman.
‘Skin care for food, food for skin care…not sure where it all leads,’ said another.
Michelle claims the result of the test is due to a chemical reaction – and a moisturizer would have some effect
“This is the stupidest test. Obviously this is a marketing tactic, but still very stupid. Sunscreen is not meant to work on bread and even if it did, it wouldn’t tell us anything about how it works on the skin,” added a third.
But there were also a worrying number of people who believed the first demonstration.
This isn’t the first time the popular beauty science social media star has turned to sunscreen.
She recently revealed why you should never buy aerosol sunscreen — and even the TGA is taking another look at them.
She said each can of aerosol sunscreen contains only enough SPF for two or three full-body applications.
Michelle Wong, a scientist obsessed with beauty products, posted a video on her Lab Muffin Beauty Science Instagram explaining the problem
“This study found that a standard aerosol sunscreen contains about a third of propellant,” she said, citing a study from the University of Technology in Queensland.
“But it could be as much as 60 percent,” she added.
She explained that the propellants are pressurized gases that help push the sunscreen out of the can.
“SPF testing is done on the sunscreen without the propellant, so you’re actually taking in about a third less product than it says,” she said.
“Some of the propellant also ends up on your skin as a liquid, so it’s hard to say how much sunscreen you actually applied.”
The aerosols usually use: butane, propane, isobutane and hydrocarbon – which are on the can label.
“The Australian TGA is currently evaluating aerosol sunscreens because of this study…stay tuned,” she wrote in the caption.
And her video struck a chord with many of her followers.
‘This is so wild! No wonder I’ve always thought these weren’t effective,” wrote one makeup artist.
Some revealed that they were burned after using the sunscreen, not knowing it was off.
†Can confirm from personal experience. Which also meant explaining to a burn surgeon colleague why my back was bright red,” said one doctor.
She also explained the common gases used in the aerosol sunscreens
“My poor man has literally just come home from a fun day of golf on the golf course… SUNBURN. When asked if he had applied sunscreen, he answered yes…and yes, it was spray. I just showed him this video, and it sold. No more spray cans for us. Just lotion…blobs of it,” one woman wrote.
Others were stunned by the results of the study.
‘I’ve never thought of this before. I liked using them because they are faster but luckily they sold out at the propellant anthelios so I didn’t get it this year,” one woman wrote.
Michelle said that while they were handy, she couldn’t get around the volume issue.
‘They sure are handy! I think they’re okay if you spray a ton on them, but the 2/3 value is just disturbing to me.”
She added that pump sunscreen has its own problems, but is not affected by the aerosol problem.
