The latest sunscreen blocks not only UV rays but also blue light and near infrared rays! ~Sapporo travelogue~

Hello.

I am Eriko Koyanagi , an AOHAL cosmetics evangelist and cosmetic dermatologist.

I went to see the Sapporo Snow Festival. It was my first time visiting Sapporo in the middle of winter.

It was snowing heavily, but since it was my first time, I thought, "Oh well, I guess it's normal," and actually enjoyed the heavy snow. I even bought snow boots specifically for this business trip.

Everyone at the restaurant and hotel was surprised and asked, "You walked through Odori Park in this snow?!", to the point that it was almost embarrassing for us. This is Hokkaido, right?

The next morning, I opened the Hokkaido Shimbun newspaper in my hotel room and was surprised!

What a record-breaking snowfall!
No wonder the snow was piling up on my head.

The snow storm has subsided, but now we're experiencing a brutal UV storm!
First of all, the pure white powder snow reflects UV rays with all its might , creating a 360-degree photoaging hell with no way to escape!

I was joking too much. Sorry, but...
UV rays are sure to be present even in the middle of winter.
Of course, the amount is less than during the peak summer months, but if you leave your skin unprotected, it can still be damaged.

In fact, UV rays are said to account for 70 to 80 percent of skin aging .
"UV protection all year round" is the golden rule for beautiful skin .

Recent research has shown that UV rays aren't the only thing that are bad for your skin when it comes to sunlight.

Can I explain it here?
Light is a type of electromagnetic wave.

Oh, don't stop reading

Since electromagnetic waves are also waves, they come in various wavelengths.

Electromagnetic waves with very short wavelengths are what we call "radiation," such as gamma rays and X-rays.

On the other hand, waves with very long wavelengths include television and radio radio waves and microwaves from cell phones.

In between these wavelengths, there is what are commonly called the "seven colors" of visible light , ranging from violet to blue, light blue, green, yellow, orange, and red. Yes, these are the "light that the human eye can see."

When the wavelength is a little shorter than violet light, the electromagnetic waves are no longer visible light. This is what we call "ultraviolet light" (UV) . There are three types: A, B, and C.

On the other hand, near-infrared light has a wavelength a little longer than red light, and the next wavelength is far-infrared light. As you can see from heating appliances, these rays carry heat, but they are also invisible to the eye.

Electromagnetic Spectrum

The sunlight that hits the earth is made up of UV (ultraviolet) A and B, purple to red visible light, and near-infrared rays .

Here is the conclusion (sorry for the wait!)

Cutting out only UV rays, as in the past, is no longer enough to prevent skin aging caused by sunlight. Visible light and near-infrared rays must also be cut out!

So what should we do?

In fact, there are already several types of creams on the market that can block both visible light and near-infrared light .

We at ZERICO are now able to deliver a sunscreen cream that blocks UV rays, visible light, and near-infrared rays .

The cutting power is comparable to, if not superior to, existing products.

Another thing is that we were able to keep the price of this sunscreen cream more affordable than previous products.

Sunscreen cream is not effective if you apply a thin layer of it. If you skimp on the amount of expensive cream you use, it just ends up being wasted every time, which is a real waste.

Be sure to apply sunscreen cream to your skin. Make it a habit to do so every morning, starting from the winter. And prepare for the season when the sun's rays get stronger!

But I'm really glad I went to the Sapporo Snow Festival. I was only there for 24 hours, but the snow fell really hard during that time.

Perhaps the "Land of Trials" has welcomed me? I'll come back next time to be tested more seriously!
