Why K-Beauty Became So Popular Around the World — What I’ve Seen Living in America

From curious Uber passengers to K-Beauty shelves across America, I’ve watched Korean skincare become something I never imagined it would be.

About ten years ago, I drove for Uber for a short time.

Because I was a woman driver, passengers were often curious about me. They would ask where I was from, how long I had lived in America, and surprisingly often, they would ask my age.

Whenever I told them I was Korean and shared my age, I often got the same reaction.

“Really? What skincare do you use?”

I remember finding those conversations amusing.

At the time, Americans were beginning to hear more about Korean skincare, but K-Beauty was nowhere near as visible as it is today.

I certainly never imagined that one day I would walk into major American beauty stores and see Korean skincare everywhere.

But that's exactly what has happened.

I Remember a Very Different America Why K-Beauty Is So Popular Around the World

I came to the United States nearly 40 years ago.

Back then, Korean cosmetics weren't something you expected to find in mainstream American beauty stores.

If you wanted Korean products, you usually had to know where to look.

Today, the experience is completely different.

I walk through Sephora and see Korean skincare brands displayed alongside major international beauty names.

When I visit TJ Maxx or Marshalls, I'm sometimes amazed by how many Korean skincare products I find. Korean beauty is no longer hidden in a tiny corner.

And now Olive Young, one of Korea's best-known beauty retailers, has entered the U.S. market.

For someone who remembers what America was like nearly four decades ago, this transformation feels remarkable. Why K-Beauty is so popular became clearer to me as I watched Korean skincare slowly move from something unfamiliar to something I could find almost everywhere in America.

And as a Korean woman, I have to admit:

It makes me proud.

So Why Did K-Beauty Become So Popular?

I don't think there's just one reason.

Korean beauty became known for innovative products, interesting ingredients, lightweight textures and skincare routines that made taking care of your skin feel almost enjoyable.

But I think there's something deeper behind its success.

Korean beauty culture has long placed importance on taking care of the skin itself, rather than simply covering imperfections with makeup.

Hydration.

Texture.

Brightness.

Sun protection.

Healthy-looking skin.

Today these ideas may sound obvious, but they helped shape the way people around the world began thinking about skincare.

K-Beauty Made Skincare Interesting

Another thing I appreciate about Korean beauty is how quickly the industry continues to develop new ideas.

Serums, essences, ampoules, sheet masks, sunscreens and eventually increasingly sophisticated home beauty devices became part of the conversation.

Some products are inexpensive and simple.

Others involve much more advanced formulations or technology.

Of course, that doesn't mean every Korean beauty product is wonderful.

I've bought products and beauty devices that were heavily advertised and personally didn't notice enough of a difference.

Those experiences actually made me more selective, not less interested in beauty.

At this stage of my life, I don't want something simply because it's trending on social media.

I want to know:

Does it actually make a difference for my skin?

And Yet, I Didn't Discover Vitamin C Serum Until My 60s

This part still makes me laugh.

I'm Korean.

I'm writing a beauty blog.

And I didn't seriously start using Vitamin C serum until I was around 60. 😊

For years I used skincare products without really thinking about individual ingredients.

It wasn't until later that I became curious about what I was actually putting on my skin.

Vitamin C was one of those discoveries.

Once I began using it consistently as part of my skincare routine, I personally became much more aware of the brightness and overall glow of my skin.

And I remember thinking:

Why didn't I learn about this sooner?

But perhaps there are other women like me.

Maybe you've used creams and lotions for decades without ever really thinking about serums or active ingredients.

That's one reason I want to write about these things now.

Because it's never too late to learn something new about taking care of ourselves.

I didn't seriously start using Vitamin C serum until my 60s. Sometimes the simplest beauty discoveries come later in life.

Beauty After 60 Feels Different

When I was younger, beauty often meant looking prettier.

Now it means something different to me.

I don't expect to look 30 again.

And I'm not trying to.

But I enjoy seeing healthy-looking skin.

I like learning what works for me.

I enjoy getting dressed, keeping my long hair, traveling, discovering beautiful places and continuing to be curious about life.

And yes, when someone tells me,

“You look younger every time I see you.”

I'm certainly not going to complain. 😊

Beauty after 60 isn't about trying to become the woman I used to be.

It's about taking good care of the woman I've become.

Beauty after 60 isn't about turning back time. For me, it's about taking care of myself and enjoying life.

Behind K-Beauty Is Something We Don't Always See

As I became more interested in skincare, I started becoming curious about something else.

Who actually develops these products?

We see beautiful bottles and packaging on store shelves, but behind a successful skincare product are researchers, formulators, ingredient specialists and manufacturers.

And this is another part of the K-Beauty story that I think deserves more attention.

Korea didn't suddenly become good at making skincare because K-Beauty became fashionable.

There are researchers who have spent decades developing cosmetic formulations and technologies.

One of the people I learned about through the products I now use is Dr. Byung-Ki Cho, a veteran Korean cosmetics researcher.

According to Derm Story, where he serves as CEO and R&D Director, Dr. Cho has spent more than 40 years in cosmetics research and development and has been associated with 225 cosmetic patents, described by the company as the highest number held by an individual in Korea's cosmetics industry.

His career has included senior research roles within Korea's cosmetics industry, including research leadership positions at major Korean cosmetics companies.

Learning about people like him gave me a different perspective on K-Beauty.

What we see today at Sephora is really the visible result of decades of Korean research, formulation and manufacturing experience.

The Research and Manufacturing Behind Uni&Core

This brings me to Uni&Core, the skincare and home beauty system I currently use.

One of the reasons I became interested in the company was learning more about the research and manufacturing behind its products.

Uni&Core's own company history describes the brand as bringing together Derm Story, Suheung and BF Bio, combining cosmetics research, manufacturing and biotechnology expertise.

That interested me because, by this stage of my life, I'm much less impressed by advertising alone.

I want to know who developed something.

I want to know where it comes from.

And I want to understand the thinking behind it.

My experience with Uni&Core is also what made me much more serious about home skincare and beauty devices.

But I want to be clear about something.

I don't believe a product is automatically good simply because it's Korean.

I've used Korean beauty products that I loved.

I've also used some that didn't impress me.

The same is true of beauty devices.

What matters to me now is the combination of research, formulation, technology, consistency—and ultimately what I observe on my own skin.

As I've learned more about skincare, I've become increasingly interested in the research and formulation behind the products I choose.

From Skincare to Home Beauty Technology

My curiosity about skincare eventually led me to something I had never expected to become so interested in:

home beauty technology.

I had tried home beauty devices before, but some left me wondering whether they were really doing much for my skin.

Later, I began using the Uni&Core Derma Home system.

That experience changed the way I thought about home beauty care and made me more interested in the relationship between skincare formulations and beauty technology.

It also made me realize just how sophisticated the Korean beauty industry has become.

We're no longer talking only about sheet masks and cute skincare packaging.

Korean beauty now includes serious research into formulations, ingredients and home beauty technology.

My interest in Korean skincare eventually expanded into home beauty technology.

From “Korean Cosmetics” to K-Beauty

Sometimes I think back to those Uber passengers from about ten years ago.

They would hear that I was Korean.

Then they would hear my age.

And almost immediately:

“What skincare do you use?”

Maybe they were onto something. 😊

At the time, I didn't realize how quickly the world's interest in Korean skincare was growing.

Today, Korean beauty has moved far beyond Korea.

K-Beauty products sit on shelves throughout America.

Olive Young has expanded into the U.S., and Korean brands are increasingly visible through major American beauty retailers.

Korean cosmetics exports reached a record $11.43 billion in 2025, illustrating just how global the industry has become.

For someone who came to America nearly 40 years ago, that number represents more than business growth.

It represents a change I've actually watched happen.

Why K-Beauty Makes Me Proud

I'm proud that Korean beauty has become recognized around the world.

But I'm not proud simply because the products come from Korea.

I'm proud of the innovation, research and persistence behind that success.

I'm proud that something that was barely visible in American mainstream beauty stores when I first came here can now compete on a global stage.

And I'm fascinated that, at this point in my own life, I'm finally becoming more interested in the very industry that was growing alongside me.

Perhaps that's the funny part of this story.

K-Beauty became global.

And somewhere along the way, in my 60s,

I finally became a real skincare enthusiast. 😊

Beauty Is Still Something I'm Discovering

There's still so much I don't know.

There are ingredients I haven't tried.

There are technologies I'm still learning about.

And there will certainly be products that don't work for me.

That's okay.

That's exactly what I want gokbeauty to be about.

Not telling women:

“You need this.”

But sharing:

“I tried this. Here's what happened to me.”

And whether it's Korean skincare, Vitamin C, home beauty technology or simply learning how to take better care of ourselves after 60, I think there's something wonderful about continuing to discover new things.

Because beauty doesn't have an expiration date.

And neither does curiosity.

Maybe that's one of the reasons K-Beauty speaks to me more now than ever before.

Beauty doesn't have an expiration date—and neither does curiosity.
