These days, skincare and cosmetics companies are packing SPF into a variety of their products.

如今，護膚品和化妝品公司在各種產品中加入防曬劑。

We're talking lotions, sticks, powders, sprays.

像是防曬乳、防曬棒、防曬粉和防曬噴霧。

It's extensive.

範圍很廣。

And while these products have been tested in the lab to make sure they actually deliver the SPF on the packaging,

雖然這些產品已經在實驗室中進行了測試以確保它們確實達到包裝上的 SPF 值、

they don't always tell you how much you need to apply.

製造商並不會告訴你需要塗抹多少的量。

They tell you to "apply liberally," but what does that actually mean?

他們告訴你要「大量塗抹」。但這到底什麼意思

Does it matter if I use a stick or a lotion or a spray?

使用棒狀、乳液狀還是噴霧狀有任何區別嗎？

So today, I'm going to perform a not-totally-scientific test of some broad spectrum sunscreens using this UV camera.

所以今天，我要做一個不完全科學的測試，使用這款紫外線相機對不同類別的防曬產品進行檢測。

[Sunscreen appears dark in a UV camera because it absorbs UV rays.]

[在紫外線相機中，防曬霜呈現出深色，是因為它吸收了紫外線。]

While this camera isn't a perfect measure of UV protection, it'll be able to show whether I get an even application or not.

雖然這款相機檢測紫外線防護的性能並不完美，但它可以顯示我是否均勻地塗抹了防曬。

Most of the products that I'll be using are what are commonly called chemical sunscreens.

我接下來要使用的大部分產品就是通常所說的化學防曬。

That means they contain ingredients like avobenzone and octinoxate that absorb UV rays to stop them from damaging the DNA in your skin.

它們含有像阿伏苯宗和甲氧基肉桂酸辛酯這樣的成分，可以吸收紫外線，防止其損害皮膚中的 DNA。

That DNA damage is what causes sunburn, skin cancer, and eventually wrinkles.

DNA 損傷是導致曬傷和皮膚癌的原因，最終產生皺紋。

First, I'll be trying a sunscreen stick, which I'm kind of excited about because it seems really convenient and kind of fun to apply.

首先，我要試用防曬棒，我有點期待，因為它看起來真的很方便，塗起來也很有趣。

Oh, that's very effective.

哇，真有效。

That's wild. Look at that.

好誇張，快看看。

You can blend it.

把它抹開。

Solid.

很均勻。

Love it.

我喜歡。

I don't know if I'd want to use this on my whole face. It's kind of greasy.

我不知道我是否願意把它塗在整張臉上，有點油。

Might clog my pores a little bit, but I mean it's surely blocking the UV rays.

可能會有點堵塞毛孔，但它肯定能阻擋紫外線。

Now I'm going to try some powder makeup that claims to have an SPF of 30.

現在我要試試聲稱有 SPF 30 的粉狀化妝品。

I'm a little skeptical of this because dermatologists say you can't really rely on the SPF in makeup.

我對此有點懷疑，因為皮膚科醫生說，化妝品中的 SPF 值並不能依靠。

I'm not really seeing much of anything.

我什麼也沒看到。

Well, maybe a slight, slight darkening, slight blockage, but I guess I was right to be skeptical. It's not very effective.

好吧，也許有稍微，稍稍的變黑，稍微的防曬，但我想我的懷疑是對的，這不是很有效。

See what happens if I keep piling it on.

看看如果我繼續疊擦會發生什麼事。

Yeah, I mean, compared to the stick, it's a little... not great.

沒錯，和防曬棒比起來，這有點... 不是很好。

Not great compared to the stick.

跟防曬棒相比，並不出色。

Next, I'm going to try a relatively new product on the market.

接下來，我要嘗試一種市場上相對較新的產品。

It's an SPF 50 facial setting spray that claims it can protect you from the sun without messing up your makeup.

這是一款 SPF 50 的臉部定妝噴霧。它聲稱可以防曬且不影響妝容。

Oh there.

哦，有了。

That showed up a little bit.

這編有出現一點。

You can definitely see it's not a wide breadth of coverage.

但可以肯定的是，它的覆蓋範圍不是很廣。

It's a little spotty.

有一些不均勻。

Yeah, I'd be wary of using this too.

我也會謹慎使用這個產品。

I guess maybe it would be good if you already used lotion underneath your makeup, and then you can use it as this extra boost perhaps,

我想如果你在化妝前先塗防曬乳，並把它當作額外的防曬，可能會很不錯，

but yeah, I would not rely on a setting spray either for SPF protection alone.

不過，我也不會只依賴定妝噴霧來作為防曬保護。

A lot of it kind of blew in the wind too.

噴出來的很多都隨風飄散了。

Just was, you know, it's not like all of this product went on my face, so maybe it was a little wasteful as well.

並不是所有產品都塗在了我的臉上，所以可能也有點浪費。

Next, I'm going to try good old-fashioned lotion sunscreen.

接下來，我要試試傳統的防曬乳。

I want to do some lotion on this half of my face, and then we'll see what happens.

我想在這半邊臉上塗點防曬乳，然後我們再看看會發生什麼。

Oh, man. That's the stuff.

哦，天啊，就是這樣。

Yeah, that looks about as effective as the gold standard stick.

看起來效果跟表現一級棒的防曬棒差不多。

Yeah, it looks like I missed, I guess I missed around my eyeball.

看來我這邊沒塗到，我想我的眼球周圍沒塗到。

And kind of underneath my nose a little bit,

還有我鼻子下面這裡一點沒塗到，

but yeah, that looks, I mean that makes me feel a lot better if I was going out in the sun for sure.

但是，如果我確定要出去曬太陽，這看起來讓我感覺好多了。

It's definitely blocking a lot of the rays.

它肯定會擋住很多光線。

Oh, and I totally missed my ear.

我完全忘記塗我的耳朵了。

I always forget my ears.

我總是忘了塗我的耳朵。

Don't forget your ears.

別忘了耳朵也要防曬。

I would definitely feel very comfortable going out in the sun with this, as opposed to just some outer spray.

相比只是噴一些外部噴霧，塗防曬乳讓我外出曬太陽會感覺很自在。

This really looks like it's blocking and absorbing those UV rays for sure.

這看起來真的像是在阻擋並吸收紫外線。

I forgot I have this lip balm with SPF 30.

我忘了我有一支 SPF 30 的潤脣膏。

You also have to protect your lips.

嘴脣也要防曬。

Your lips get sunburned too.

嘴脣也會被曬傷的。

Oh, yeah. See?

看到了嗎？

It's great. Love to see it.

太棒了，我很樂見這個結果。

Looks like lipstick in this camera.

在這臺相機裡看起來像口紅。

Nice.

不錯。

Now I'm going to try to "apply liberally" to get one half of my face completely covered, and we can compare the two.

現在我要嘗試「大量塗抹」，讓我臉一半的臉完全塗上防曬，然後我們可以進行比較。

That's just wild.

太誇張了。

It's very comforting to know that the sunscreen really works.

這讓我感到非常安心，防曬乳真的有效。

It's not just, you know.

這不是隨便塗塗。

You trust the science.

要相信科學。

This is just a new world.

這是一個新世界。

Try to rub it in a little bit.

試著揉一揉。

You can see the way you apply sunscreen really matters.

可見，塗抹防曬的方法真的很重要。

Like for me, I always miss my ears and the area around my eyes,

就像我，我總是忘記塗我的耳朵和眼睛周圍，

but it also seems that the lotion out of all of them is definitely the way to go for a base, although the stick was also very impressive.

但看起來在所有產品中，防曬乳肯定是作為基底的最佳選擇，雖然防曬棒也表現得很好。

And I also liked the spray and maybe a powder as a touch up if you have a good base layer, but I wouldn't really rely on them alone.

在有一個良好的防曬基礎的前提之下，我也喜歡防曬噴霧，也許還可以使用粉狀產品作修飾，但我不會只依賴它們。

I feel much more comfortable with my trusty lotion or stick like on this side.

我對可靠的防曬乳液者像這邊使用的防曬棒感覺更加安心。

But it really just goes to showhow much your application technique matters.

但這顯示了你的塗抹防曬的技巧有多重要。

Remember, it's important to wear a sunscreen all year around to protect yourself from skin cancer and premature aging.

記住，一年四季都要塗抹防曬，以防止皮膚癌和過早衰老。

UV rays can still damage your skin in the winter.

紫外線在冬季仍會傷害皮膚。

Seeing the results from this UV cam has definitely inspired me to keep up with my daily sunscreen habit.

看看這個紫外線攝像頭的結果，這無疑激勵我繼續養成每天塗防曬的習慣。
