Thank you for reading our column today.

What is blue light?

It's a term you hear often, and I'm sure many of you are familiar with it.

From the smartphone, computer screens, LED lights, etc. that we see every day

It is a type of high energy visible light that is emitted.

Visible light is the light that can be seen by the human eye.

The wavelength of visible light is approximately 400 to 800 nm (nanometers), while blue light is 380 to 500 nm. Anything shorter than 400 nm becomes ultraviolet light, which is invisible to the human eye.

It is no exaggeration to say that we live surrounded by blue light.

What impact will this have?

When you hear the term "blue light," many people may think it's bad for your eyes.

In fact, it also affects our skin through photoaging.

UV rays and blue light have similar wavelengths to visible light.

UVB rays: Causes the surface of the skin (epidermis) to become red or dark

UVA rays: When they reach the dermis, deep below the epidermis, and cause damage, the production of collagen and elastin is reduced, causing loss of firmness and sagging, which can lead to wrinkles .

Blue light: Like UVA rays, it penetrates deep into the dermis layer of the skin.

Not only does it cause loss of firmness and sagging, but it also weakens the skin's barrier function.

Furthermore, it generates active oxygen, which promotes pigmentation and produces melanin, causing blemishes and dullness .

If you've been feeling a bit tired lately,

Maybe blue light is the cause besides fatigue?

Blue light protection and prevention methods

Get some antioxidants!

Not only does it protect against sunburn, it also destroys active oxygen.

Be sure to take in vitamins C and E from the inside.

There are many things that can be changed through inner care.

Installing a blue light blocking filter on your PC or smartphone.

Small daily actions will affect your skin in the future!

Continue doing what you can comfortably do every day.
