The falling mercury does not seem to concern the who's who of Korea's pop music world.

They arrive for another awards ceremony and cream for the cameras.

You think K-Pop stars are beautiful?

Yes, popular and beautiful! Their dancing -- perfect. Their face is different. Big eyes

This is what sends young Koreans into a frenzy and has taken the world by storm. Catchy tunes

and flashy performances by doe-eyed starlets and dapper pin-up boys. They rarely speak

publicly about their penchant for plastic, but cosmetic surgery among K-Pop stars is

so rampant it is parodied.

You know I'm pretty, but with no surgery? You wouldn't know the difference. Idols have

all had plastic surgery, you call me 'plastic monster.' Plastic face.

But the pursuit for perfection extends much further than Korea's entertainment elite.

It makes me happy to think that I'll look prettier after today, I am looking forward

to my surgery.

Hwain has just finished high school, and her mother has given her a graduation gift. Eye

surgery.

I hope it turns out well and she becomes prettier. When Hwain looks at herself she thinks she

is ugly. We don't think this way but she does. Because every K-Pop star on TV looks so pretty,

like a doll, she sees them as a standard of what is beautiful.

Hwain will be going to university with new friends and new opportunities.

So we thought if plastic surgery will help her feel more confident, maybe it is not such

a bad idea.

Hello.

Hwain is about to undergo what is called double eyelid surgery. Her surgeon, Dr Rhee Se Whan

will create a second eyelid to make her eyes look bigger. It is one of the most popular

procedures here in Korea. I'm told an increasing amount of teenagers are asking for this procedure

straight out of high school, before they head to college.

So what I have done is puncture very small holes where her second eyelid will be.

The whole procedure is over in 40 minutes. Hwain will spend a short time in recovery

before heading home, and will return in a week to have her stitches removed.

K-Pop stars and Korean celebrities have influenced. If you look at a before and after picture

of a K-Pop star, you will see that they have gotten prettier. When people see the change,

they want to be pretty as well. They want to look as good as them.

Like Hwain, Gina, Sally and Laura are recent high school graduates, and have agreed to

meet me to talk about image and plastic surgery.

I don't think any celebrity has not retouched their face.

We grab a few magazines and head to a nearby cafe.

Almost everyone gets it - especially in normal high schools. Once people graduate, almost

all of them get double eyelid surgery done.

Have you felt pressured to do it?

I've thought about it. Not in America, but in Korea, there are so many more people who

are talking about it. You think, "Oh, should I get it done too?"

Two of the girls also went to high school in the US. They say surgery is driven by an

admiration of celebrities.

That is the difference. Like, in America, you will say, "I want a skinnier nose." But

in Korea, they say, "I want the eyes of whoever, I want the nose of whoever. Please make my

nose into the style of this star."

Who are we looking at here?

They are 9 girls and they are in an idol group called Girls Generation.

Have they had surgery?

Yeah. Definitely! All of them - 100%!

Many, many, many plastic surgeries. Many! Every time they come out, they come out with

surgery...Their faces change.

Eyelid surgery can cost up to $2,000. If you cannot afford it, the girls tell me there

is another way of getting the coveted big eyes.

This is what Koreans call the double eyelid sticker. I've never used it before but according

to my friends, they said that it is the easiest and the cheapest way of making double eyelids.

I took it off! So it looks like a half moon.

Yes! Look at her eyes!

This is the district of Gangnam, home to K-Pop's major entertainment companies, and it's also

home to South Korea's beauty belt - an area of the highest concentration of plastic surgery

clinics in the world, which caters to an ever increasing foreign clientele.

So from here the entire street has more than 300 plastic surgery clinics.

This street alone.

Yes, this street alone, each building has more than three or four plastic surgery clinics.

Artist Eunjeong says the rapid growth of Koreas plastic surgery industry is concerning, especially

because of its connection to the entertainment world.

They send people from the agencies, they can get discount and then from that, they can

use their face for the commercial advertisement.

Even the subway has become a billboard for cosmetic surgery.

They change their facial shape, they cut down their cheekbone, made their eyes bigger their

face, their eyes change. They make big eyes, front and back, and they put some fat underneath.

They implant hair.

Eunjeong knows the passageways well - they inspired her to create an art installation

on what she calls Korea's obsession with beauty.

They choose one or two types of very beautiful women, with an ideal face. And every woman

tries to turn into exactly the same.

This is my studio, and this work is from my exhibition Body Factory. Every work in here

comes down to the people losing their identity. That is why they treat their body as a product,

they are losing the meaning of who they are.

Do you feel like that is happening as a society here?

Yes.

Because I heard it described as a plastic surgery obsession.

Yes.

Do you think that Korea is obsessed with plastic surgery?

I don't think it is obsessed with plastic surgery but obsessed with the way they look.

We are heading outside Seoul's city to meet a man who's had several procedures done to

his face on his jaw, his nose, his eyes. Now, while it is true that more women get plastic

surgery here in South Korea, it is by no means exclusive to women. A growing number of men

are also getting surgical procedures.

If you cut your jawline a bit, I think you could be really pretty.

At just 21, Hwan Kim has had 17 procedures so far.

The number of times? I have done my eyes three times, my nose once, my chin, cheekbones,

my squared jawline.

And that's not counting botox injections and fillers.

You don't want to show us the pictures? Why?

I'm embarrassed. Shame, shame.

This is what Hwan looked like before he began to reshape his appearance.

I had a complex about my appearance, so the most important thing is when I met up with

people I used to wear a mask or when I talked to people, I'd always cover my mouth.

Hwan has spent $30,000 on cosmetic surgery. And his friends want surgery too.

My nose, cheekbones, chin and what else did you say? Botox!

I want to get braces and shave down my jaw.

Night falls and the city streets come alive. Hwan and his friends are getting ready for

a night out. He says his cosmetic compulsion is paying off.

Now I have a lot of confidence in the way I look, I want to meet people, I want to meet

girls and I really believe this has been made possible through plastic surgery.

In another dimly-lit room on the other side of Seoul is a very different music world.

Playing tonight is an indie band called Love X Stereo. Its front woman, Annie, has invited

me to watch them perform. She spent years in the pop industry signed to a mainstream

entertainment company as a solo artist. In order to make it big, she was told to change

her sound, and her face.

They liked my voice, but they didn't like my appearances, so they wanted me to have

plastic surgery here and there, like nose, my eyes. They occasionally talked about my

teeth a lot because I have very - yeah, rabbit teeth.

Why did you decide against it?

Because I like my face.

The band rehearses and records in its own small rented space. Each member has a second

job to support themselves - a small price to pay, says Annie, for creative freedom.

Some of the criticisms of K-Pop has been that it is a very manufactured industry.

Yeah, absolutely. It is. They kind of, you know, recruit young kids, like 13, 14, and

they make something - they kind of grow them into - in a certain way, and cut them along

the way, and make a group.

Here we go, this is the band!

K-Pop dominates much of Korea's entertainment news.

Ladies and gentlemen, welcome to the show, we are happy to have you here with us on Showbiz

Korea Time.

Adrien Lee hosts Showbiz Korea, a daily entertainment show broadcast around the world on Korea's

only English-speaking network.

We have some K-Pop news coming your way - big news, actually.

Adrien also hosts his own radio show on Korean culture. He says even though pop stars get

surgery to improve their prospect, talent still plays a big part in the K pop industry.

No matter how much plastic surgery you get, it will not make you a big star. You need

to have talent. Maybe on top of that, later on you can add a plus alpha, with a little

bit of plastic surgery, but that won't initially play a big role for you to become a huge star.

As he shows me around the network, we meet a group hoping to become the next big thing.

We just bumped into a group, coming into record a show here at Arirang. You mentioned stuff

about the visuals, the looks. You can have a look - this is a new group. Can you introduce

yourself.

One, two, three... Purple, purple, Purpley. Hello, we are Purpley!

OK, there you go! Great! That is how they introduce themselves.

So many young people look up to them, and think they are really attractive.

Good! We're very nervous, we hope to have a lot of influence on the younger generation.

They tell me they have not had any surgery. But, as they walk away, I wonder whether that

will change. 18-year-old Hwain has returned to her clinic a week after her eye surgery

to have her stitches removed. Her eyelids are still swollen, but she is positive about

the result.

Are you happy with your surgery?

Yes. Yes, I'm happy.

And mum is also satisfied.

Well, double eyelid surgery generally makes people prettier, I think Hwain will look even

prettier, more than I expected.

Ten minutes after arriving, Hwain leaves with new eyes. The first step, I'm told, to becoming

beautiful.
