Hello.
I am O Ga-na, a dermatologist with 16 years of experience.
K-pop is once again taking the world by storm these days.
In particular, thanks to
‘K-Pop Demon Hunters,’ which ranked No. 1 on Netflix,
interest in idols has reached a level
higher than ever before.

But when you look at idols on stage,
there is one common trait.
That is their clear, white skin.
As they continue their activities after debut,
many of them become even more fair and radiant.
What on earth is the secret?
Today, I will explain the reason from the perspective of a dermatologist.

Why does idol skin keep getting whiter?
There are three major reasons why idol skin gradually becomes brighter.
-
Changes in lifestyle habits
After debut, idols manage their diet extremely strictly.
They reduce irritating foods, drink plenty of water,
and make sunscreen use a daily habit.
-
Intensive dermatology care
Honestly, cosmetics alone have their limits.
That is why they combine medical treatments such as glutathione and vitamin injections,
whitening lasers,
and skin boosters.
-
Work environment
Most of their activities take place indoors, under strong lighting.
Because they are exposed to less sunlight and can treat skin troubles right away,
their skin tone is easier to maintain.
Three medical principles that change skin tone
The principles behind brightening the skin
are, in textbook terms, divided like this.
-
Suppressing melanin production
Tranexamic acid (oral medication), functional topical products
-
Blocking melanin transfer
Niacinamide skincare products
-
Removing already accumulated melanin
Laser toning, pico laser procedures,
glutathione, vitamin C injections
When these three are combined appropriately depending on the situation,
you can make the skin tone clearer and more radiant.
Can ordinary people also become like idols?

Skin is 80% determined by genetics.
But the remaining 20% can be changed enough through lifestyle habits and
treatment.
If you follow just these three things,
your skin tone will definitely change.
In closing

Idol skin is not something you are simply born with.
(Actually, when I see idols who come to our clinic,
some are naturally like that, but there are more who are not..^^)
When lifestyle habits, steady care,
and professional treatment are added together,
we can definitely get close to it as well.
Skin is 80% genetics,
but the remaining 20% can be changed starting now.
Thank you for reading this long post.
