651: Your Judgement About Pockets
00:03:48
out in the afternoon i like i i have been i have worn more sunscreen in the last two weeks than i have
00:03:43
to sunscreen like now i am putting it on every day i'm reapplying if i put it on in the morning i go
00:03:37
since i have been using the japanese sunscreen it has like it has radically changed my relationship
00:03:24
yes we know but mineral sunscreen that has its own trade-offs we talked about it a few episodes ago
00:02:40
you every sunscreen available in the u.s will have exactly the same problem i know i know it's i mean
00:02:30
i've ever felt in my entire life from sun it's the same sunscreen i've been using for like a decade
00:01:52
relevant to this show marco cursed me uh with all of the eye stinging sunscreen thing because i'm like
650: Whatever It Takes to Get the Laundry Folded
00:14:02
This is another one of those things that's like was probably true at one point, but technology marches on and it sounds like they're making the stuff, the like the metal oxides and stuff smaller and smaller in the sunscreen because that makes for a better product like it's smoother and we we have the technology to make it smaller.
00:13:56
This energy is later primarily dissipated as heat in a manner analogous to chemical sunscreen UV light absorption.
00:13:24
It is important for dermatologists to recognize that the primary mechanism of action for modern physical sunscreen agents is the very same protective mechanism of chemical sunscreens absorption of UV light.
00:13:17
Furthermore, even micro sized physical sunscreen formulations have been increasingly replaced by nanoparticle formulations.
00:12:52
However, this mechanism is at best a historic artifact from when physical sunscreen particle sizes were quite large, though such non micronized and non nanoparticulate physical sunscreens may have had a greater proportion of its perfected protective mechanism from reflection and scatter in the past.
00:12:40
So from that letter, many assume that chemical sunscreens absorb UV light and convert the energy to heat, while physical sunscreens such as zinc oxide and titanium dioxide reflect and scatter UV light.
00:11:57
Prodan Stetev writes or points us to a academic research paper, Improving Patient Communication on Sunscreen Choice, Updating Mechanistic Misconceptions.
00:11:39
And I had summarized it basically as saying chemical sunscreens have chemicals that absorb into your skin and they absorb UV rays, whereas mineral sunscreens use like fine metallic dust to reflect the sunlight off of the top of your skin.
00:11:35
My I quickly gone through the difference between chemical and physical and mineral sunscreen .
00:11:25
Marco, can you summarize for me what your discovery or assertion was last episode with regard to chemical versus physical sunscreen ?
00:11:21
We need to talk about sunscreen and Marco's new thought technology with regard to sunscreen.
649: Prove It With Cameras
01:56:05
Or, yeah, find some, uh, eBay sunscreen .
01:56:04
and sunscreen everywhere else.
01:55:39
Like I honestly, I can't imagine sunscreen with this chemical going into someone's eye
01:55:35
sunscreen .
01:55:06
Like so if it makes a difference whether you're going to wear sunscreen or not, then you're
01:54:50
Whereas, you know, in the modern era, I almost never wear sunscreen because I hate it so much
01:54:49
So I would use sunscreen .
01:54:35
The sunscreen we use was none.
01:54:31
80s and 90s, this is the sunscreen we use.
01:54:21
You know, when you look at the overall risk profile of like, I have not been wearing sunscreen
01:53:40
Did any of your sunscreen smell like cigarettes?
01:52:27
sure US manufacturers would love to sell us a new kind of sunscreen that they can advertise
01:51:58
I mean, there's risk buying, you know, American sunscreen as well.
01:51:16
and we can't get the good Australian sunscreen here.
01:51:12
But because Australia, there's so much sun, they have much better sunscreen than we have
01:51:10
It's about like, oh, a US sunscreen isn't actually blocking the sun.
01:51:05
you'll see very often is like in Australia, you know, they have the real sunscreen that works
01:50:42
I think it's always like the sunscreen that they don't want you to know about.
01:50:34
history about Australian sunscreen , which also has lots of as with all these things for
01:50:23
Yeah, but OK, it's Japanese sunscreen that I'm importing through an eBay seller.
01:49:15
And I also thought like, you know, if I'm going to be ordering like sunscreen from, you know, the EU or Japan or something like it's going to take weeks to get here or whatever.
01:49:09
I'm wearing sunscreen more now because all of those downsides are gone.
01:49:00
It's like it's night and day difference to the point where now I'm actually like wearing sunscreen more, which most of us really should.
01:48:31
And B&A does not sell international sunscreen , unfortunately.
01:47:52
But other countries have solved this problem with newer chemicals that have chemical sunscreen and therefore none of the downsides of mineral sunscreens, but chemicals that just don't sting your eyes.
01:47:44
Apparently, the process of getting them approved in the U.S. for sunscreen is apparently onerous and burdensome and terrible.
01:47:12
As soon as I involved ChatGPT, I very quickly found out, oh, here, like, I basically, I said something like, you know, my eyes burn my sunscreen .
01:47:09
No, you could have just written sunscreen , eye sting.
01:46:43
I'm surprised that you were able to find and purchase 10 U.S. sunscreens without having non-U.S. sunscreens thrown in your face by every algorithm on the entire internet.
01:46:25
Like, that didn't come up in your searches when you're buying 10 U.S.-only sunscreen s?
01:46:19
When you were doing this, you didn't, like, I figured, like, your first YouTube search would have thrown, like, Korean sunscreen in your face.
01:46:10
And so, sure, and this is why I went through every, I must have, especially at the beach house, I have 10 different brands of sunscreen s.
01:45:53
The only sunscreen s in the U.S. that don't contain it are the all mineral ones.
01:45:48
Well, avobenzone is now in every U.S. chemical sunscreen .
01:45:47
Sunscreens when we were kids didn't contain this.
01:45:05
You know what the best sunscreen in the world is?
01:44:35
And I was thinking, like, when I was a kid, I had sunscreen all the time in the summer, and I never remember it burning in my eyes.
01:44:15
And there are tinted ones that, like, a lot of – they're mostly used if you're going to be putting – if you're trying to, like, use it as, like, a foundation on your face and you're going to be putting makeup over it, they have, like, skin tone tinted mineral sunscreen s that come in various shades of brown and tan and stuff.
01:44:10
I mean, to be clear, like, you do get very white with mineral sunscreen , like, because it is just coating you with white dust.
01:43:29
If you are swimming somewhere that requires reef safe sunscreen , like most of Australia, you know, there's a reason why it's out there and it's good for that.
01:43:11
Oh, and also, mineral sunscreen , you know, it doesn't burn my eyes, but because it is a bunch of metallic powder, it does occasionally just get in my eyes.
01:42:48
Mineral sunscreen , yeah.
01:42:43
If you put this stuff, put physically, physical sunscreen , like, physically blocked sun.
01:42:17
I made the mistake of putting sunscreen on my arms and neck and stuff, mineral sunscreen, and then a few minutes later putting a shirt on.
01:42:08
Don't forget about leaving that sunscreen all over the interior of your car, like, your armrest.
01:41:38
The main downside of mineral sunscreen s, which is what I've been using more recently, is, first of all, because it's just putting metallic powder on you, it has to kind of stay a little bit goopy forever.
01:41:21
Mineral sunscreen s basically are lotions that contain very fine metallic particles, usually zinc or titanium dioxide.
01:41:20
Those are called chemical sunscreen s.
01:41:10
You know, the way sunscreen s work is they either have chemicals that absorb into your skin that themselves absorb UV rays so that they don't burn you.
01:41:05
First, I mean, first, I was like, okay, mineral sunscreen was the obvious solution.
01:40:43
So, I've just had a problem for years that, like, sunscreen just always finds a way to burn my eyes, even if I don't even...
01:40:17
Now, you might think, why don't you just not put sunscreen in your eyes?
01:40:06
Alright, so I, for a long time, have had a huge amount of trouble trying to get a sunscreen that doesn't burn my eyes.
01:39:38
European sunscreen that has that chemical we're not allowed to use.
01:39:34
Marco solved sunscreen .

440: The Reality of Magnets
00:03:11
Great, yeah. I'm covered in sunscreen and sweat because it's July and it's very hot and I've had a lot of sunscreen on, so I'm like greasy and hot, and I'm crawling around on this--
