Is Australian Sunscreen ACTUALLY stronger than Asian Sunscreen? I put them to the test!

[@CurrentlyHannah]

I didn’t realise at the time of filming but the Bondi Sands Mineral Face Fluid is NOT a water resistant sunscreen which explains why it didn’t perform well in the water test but offered great protection in the dry test. I removed some comments from the video as I don’t feel it’s fair to compare its results to other water resistant sunscreens. Bondi Sands has undergone the same regulated tests as all sunscreens in Australia and when used as directed it offers the protection written on the label. This is 100% my fault and something that I'm absolutely KICKING myself for :( Bondi Sands recommends you try their SPF 50+ Fragrance Free Body Sunscreen Lotion (which I've also heard great things about) and you can find it here: geni.us/afdov5

As a scientist, I commend your dedication to accuracy and reducing sources of error, but most especially to your dedication to *finding* the remaining sources of error and reporting them. I think your experiments still have a lot of value despite the problems you list -- no one can ever eliminate all error anyways. Also idk exactly what the issues you had with your scales were, but just know that with the very precise lab scales, you can literally watch water evaporate in the weight measurement, so if you couldn't get your scale to settle down, you may have just been seeing evaporation!

[@terryjohnsen1689]

I worked as an industrial chemist for 40 years and was impressed by your honesty and hard work in determining and overcoming the shortfalls in your testing method. I think you’d make a great chemist but as you learnt it’s not easy work and people don’t appreciate the extra work required for a reliable result compared to a made up one. The only way to make conclusions on the results is to do multiple tests and use statistics to determine the variance for each tested product. You can then apply a statistical confidence level that one sunscreen is better than the other. For your test scheme you have to do the experiment at least 10 times to get enough data for the statistical testing of the data, and that’s assuming good testing methodology and low variance between each test. Anyway, well done you won my respect.

[@katyc.8663]

I like the take-away that (almost) any sunscreen is better than none. I like your flawed testing. It captures the real world better than lab testing. Like the expired sunscreen. I'm sure many of us have used expired sunscreen because it is what we had on hand. The skin stretching? That is a natural consequence of moving. Higher temps? I live in Texas, my sunscreen gets left in the car. It gets rather toasty in the summer. These are real world things. Thanks for the tests. Mad props to actually exposing yourself to the sun like that.

[@gigibeal]

yes to this. I think that's what makes this more enjoyable despite the fact it isn't as scientific as lab tests!!

[@WiseFamin]

Yes! I appreciate Hannah's transparency very much indeed, but I was also thinking that her results are much closer to real-world results that most of the rest of us would get! One of my physicians is always saying that results acquired in the lab rarely apply to regular humans in the clinic because regular humans don't live in labs. So you have to compare like with like--in this case, square X performed better than square Y on Hannah's back/leg on that particular testing day. Another flaw to consider is that Hannah's skin type isn't the same as my skin type (hers is most likely drier than mine), and the different formulations will stick to different skin types differently. Does that have an effect on efficacy? Who knows? (I was thinking formulations that pill will rub off more easily, thus possibly giving less coverage, and many formulas pill on my very oily skin.) And we didn't take into consideration how sweat affects efficacy, which I'm sure it does, and for many of us in the real world, is a factor completely out of our control in summer! My big takeaway is that covering your skin (with clothes/hat/duct tape) is probably the best sun protection possible! And when that's not possible, some sunscreen is always going to be better than no sunscreen (or just vitamin C by itself)! Hannah, thanks for being our guinea pig!! Now if only I could get someone to do this sort of testing with the sunscreens we get in US drugstores, since our regulations are so very different from the rest of the world!

[@godminnette2]

Okay, but in order for those results to mean anything, they would need to be compared against ones that hadn't been exposed in that way. Was the sunscreen ineffective because it was worse as baseline or because it was expired? Which sunscreens were left in a hot environment, and if so, which of those if any faced any degradation?

[@DannyChen712]

Agreed, tons of upvotes for the original comment but all of those things should be individual variables, like which sunscreen does the expiration date matter and which are better at resisting movement related wear. Having a bunch of variables in your test means that the results are incomplete, not that they are useless but it certainly doesn't make the results better. We can appreciate the original results without claiming that inconsistencies make science better.

[@koookeeez]

I feel like all the little "mistakes" that you made in your first back test just makes the results more important because its things we all do when we're traveling with sunscreen. Were not hyper focused on application or packaging or anything like that, we're just enjoying our vacations. Thank you so much for sharing this information!

[@braria9855]

I will add to this that spray sunscreen actually has much worse results in many tests (that just do "apply as you would" and check through an UV light or similar) exactly since spray application is quite inefficient and spotty!

[@nerolia_gaming8030]

@@braria9855 i've heard for the spray products, you spray it on the skin and then spread it evenly with hands. So "spray" is just a way the product comes OUT of the package and not the way the product gets ONTO the skin, which is also a thing that should be considered there.

Don't forget to carefully exfoliate your skin once or twice a week to remove dead skin cells and reveal a more radiant complexion. Choose sunscreen with effective and correct filters.

What I find very nice with your test, is that -> ''yes ok, they aren't lab tests'' - but they are surely closer to IRL situations than a lab can be when they test the spf. So knowing that, it's super interesting from a consumer standpoint because we have a flawed use of sunscreen even if we are super cautious about it. We can't 100% guarantee the conservation, how it interacts with our skincare, or the chemicals in the pool, our sweat, the rubbing etc. so it's super cool that you did those tests and shared it with us.

Lab tests vs field tests!

[@Sarah-cq1vb]

This is exactly what I thought as well. It’s all well and good to do lab testing but real world testing is what is really needed. Especially for the waterproof test. If you’re going to go to the beach and spend the day you are doing more than just one thing at a time. You are walking on pavement, then sand, then swimming then sitting on sand or a towel or maybe a chair you may or may not have a lot of shade. You might have to go to the bathroom ext. Even if you reapply as directed the results you will get from your sunscreen will vary on you and what you are doing and your body. Because the one thing I don’t recall her talking about is the absorption rate of these sun screens. Which is actually the main reason you have to reapply sunscreen even if you are not sweating or getting wet or anything. Your body absorbs the lotion eventually and then the outer layers of your skin are no longer protected. I learned this when I was doing my own research into sunscreen a few years back. Because I couldn’t find a good sunscreen to save my life I moved to Alabama and though I am not ginger my father was and I inherited his sun sensitivity. And Alabama sun is murderous. I resorted to clothing as my best option in conjunction with the highest spf sunscreens I could find. It’s worked out for the most part but I think it’s due to my ability to be ok with wearing pants long sleeves and a hat in the middle of summer when I do yard work more than the use of sun screen. It can be miserable but it is doable

[@CurrentlyHannah]

I really WISH I’d mentioned these in the video cuz there are a lot of questions about them: -The reason Australian sun is “harsher” than elsewhere has nothing to do with the ozone layer. The earth is actually physically closer to the sun in the southern hemisphere’s summer than the Northern Hemisphere’s summer, accounting for approximately 7-10% extra UV. -The sunscreen I used on my lower back/arms/shoulders in the water resistance test was the Aus Nivea, but generously reapplied throughout the test. +10 points for reapplication! -Bondi Sands did have a batch of their zinc sunscreen that got recalled recently but my bottle was not in that batch. -La Roche Posay is obviously French but it’s sold in Australia, has passed all the regulations there and was tested in a TGA approved lab… but for simplicity, it’s just easier to call it “Australian sunscreen” -Some people have pointed out that my ponytail covers the top square when lying on my stomach 😓 I wasn’t lying in that position for very long so I don’t know how big a difference it could’ve made but yeah, just another reason to not take my results for granted 😂

I could be wrong, but being physically closer to the sun has zero effect whatsoever on "harshness". Earth orbit the sun in an ellipsis, some times 2 million miles closer or further away. I highly doubt that the extra distance from north or south hemisphere is a contributing factor. It's likely, due to the thinner atmosphere depending on elevation.

Hi, in the industry, milligram scales (and often centigram) are _always_ operated under a glass bell or inside a special enclosure to avoid any air draft or even respiration fooling the result - temperature and light conditions also must be kept under control. One thing is very important though, as for other creams never ever have the bottle nozzle touch your skin, it could contaminate the whole product with your skin germs. On such creams, expiration dates only have a very little effect on the result, as it is more a matter of emulsion falling apart and possibly bad smell - the anti-UV compounds being quite stable, they do not change significantly in such a short time. And remember that the industry always find whatever arguments are necessary to get shorter dates, so it can sell more to gullible persons, just like with canned food, except if it can be opened by hand, which is another way to reach this goal because faster corrosion of the top semi-cutting could admit air in. La Roche-Posay is pronounced like : La Roche-Pozay (in French, only one 'S' is equivalent to the 'Z' sound).

I work at a dermatology office and that means I see a LOT of patients with skin cancer. I want to reiterate something she said: the best sunscreen is the one that you use!!! The fact of the matter is if you picked the highest quality but grossest/gardest to apply sunscreen and DONT wear it, that sunscreen is useless. Covering your body with clothing is one of the best ways to protect yourself, but if you wear sheer clothing, apply sunscreen underneath! You CAN get skin cancer even without getting burnt/without pain. And lastly, your best option is to get screened yearly, as in have your body physically looked over by a dermatologist, if you have not had a skin cancer before, when you hit around 35 years old. If you have been diagnosed with a skin cancer or have a lot of moles or spots, or you have a family history of melanoma, talk with your dermatologist about getting seen every 6 months. You would be surprised how much can happen in 6 months.

Gentleman who watched the whole video here, this was a huge effort to go to, but in my opinion absolutely worth it. This is one of the most informative videos I've ever watched, in that there's portions of this video that I'm actually going to get to use to correct mistakes in my sunscreen practice. I definitely took for granted all this time that I knew what I was doing, just because I grew up in Australia. This also definitely soothed a lot of anxieties I've picked up about making the right choice for my skin, when I hit my late 20s and started taking my skincare seriously I think I picked up a lot of worries about sunscreen, never sure I was getting a good sunscreen or that I was using it the right way even, trying to answer those questions by wading into the bullshit that is the cosmetics industry only made it worse for me. So thank you for making this and the excel sheet, this is one of those projects that's just a pure public good and it's always a nice little gift to stumble across something like this.

As a desert-dweller in the U.S. Southwest, I have noticed a difference in sun intensity between my region and where my mom's family comes from, about 800 miles directly North. Your 7% greater sun intensity makes sense to me. Due to sunscreen melting off of my forehead and stinging my eyes, I only apply it to below eye level and wear a baseball cap, usually. I have an SPF 15 or 30 facial moisturizer I use daily for protection while driving. Thank you for your hard work on this video!

Many people here, despite the intensity of the sun still underestimate the long-term effect and would apply too little too late. Seeing your video and also having watched LabMuffinsBeautyScience's video a few weeks ago is such a nice thing.

[@Misakigi]

I swam most of my life and was a swim instructor as well. I am convinced that people don't know how to apply sunscreen or keep it on. When people spray, more sunscreen goes into the air (and my lungs) than on themselves. People tanning on the beach think the less sunscreen they put on the more golden their tan will be, meanwhile they just look lobster red. The first thing kids do when they jump in the water is rub the water off their eyes, instantly wiping off their sunscreen (and into their eyes, and then they cry). As you said Hannah, the best solution is to just wear a sunscreen and wear it correctly (other than don't go outside or cover up). You may also be interested to know that synchronized swimmers (at least in the U.S.A.) use baby rash cream as a thick sunscreen on their faces during 6+hr summer practices and it does work. We can't put it anywhere else though because then it would get everywhere-as "dancers" we link arms, legs, or stand on each other for "lifts" like cheerleaders. Sunscreen on the shoulders is too slippery for the "flyer" to jump off.

[@RestorativeRenaissance]

Yes! I have used Sudocream for nappy rash as sunscreen in a pinch because it contains so much zinc. It definitely works but I look like a ghost 😂

[@aldergreen]

Baby rush cream does usually contain quite big amount of zinc oxyde, which are indeed part of the sun filters list. Not a very orthodox way, but I can see why it works. The other part of the cream consist in fats (such as petroleum jelly), which are very water resistant.

[@JillCao]

What a fun fact and I’m not surprised. Diaper cream contains a huge amount of zinc, the primary ingredient in sunblock, and the cream is formulated to be water resistant so it’s stay on the baby’s moist skin. I was in fact joking with my husband on a recent rafting trip that if we ever forget to bring sunscreen while out in the sun, we could just steal our kids’ butt cream. Glad I found proof! 😂 Side note: I’ve also used La Roche Posay’s cicaplast cream in place of sunscreen when I had forgot to bring one. It also contains zinc and is water resistant.

[@Scriptadiaboly]

Baby rash creams usually contain lots of pink oxide, it's very reasonable

[@kalisworl]

I started using diaper rash cream as a replacement for products that mainly claim to be barrier healing (such as the LRP cicaplast baume b5) and I find it both more affordable and more effective!! I just cannot use it any time other than at night and if I have to be seen I use a very small amount and always rub it between my hands because it is so thick!
