[Dermatologist Lee Yu-deuk]

Hello,

A place that creates a comfortable face, rather than excessive change.

This is Lee Jiham Dermatology Clinic.

Are your acne breakouts gone, but you are still worried about the scars they left behind? I understand very well how people feel when uneven skin that cannot even be covered with makeup makes them afraid to look in the mirror. Today, through the story of a patient who had been distressed by acne scars for a long time, I would like to explain CLO scar restoration therapy in more detail among Gangnam acne scar treatments.

A beauty consultation with real value

I am dermatologist Lee Yu-deuk.

Gangnam acne scar treatment

You need to know clearly

A while ago, a patient came into the clinic.

They had suffered from severe acne since their early 20s, and now in their 30s, they said there were still pitted scars and raised scars all over their face.

"Doctor, my acne hardly comes out anymore,

but because of the scars,

my skin looks so dirty.

Even makeup can't cover it,

and every time people look at my face,

I become more and more self-conscious,

so my confidence is fading," they said,

and I could hear the long-built-up frustration

in their voice.

It is hard enough to deal with acne itself,

and it must have been heartbreaking that, even after it went away, it continued to remain as a mark and make everyday life more difficult.

Why do acne scars form?

Acne scars form when inflammatory acne damages deep into the skin.

When acne appears, our body tries to heal itself, but in this process, if collagen is produced abnormally or insufficiently, a scar remains.

Just as a scab forms when a wound heals, the skin also cannot return to its original smooth state during recovery and instead changes into a rough, uneven texture.

There are also various types of scars.

There are many forms, such as ice pick scars, which are deeply pitted like they were pierced with an awl, rolling scars, which are rounded and depressed, and boxcar scars, which are square-shaped depressions. Sometimes raised hypertrophic scars or keloids can also form.

What is CLO scar restoration therapy?

While explaining acne scar treatment options to the patient, I introduced CLO scar restoration therapy as one of the Gangnam acne scar treatment methods.

CLO is a combination treatment that uses chemical treatment, laser treatment, and surgical treatment at the same time.

Why use all three together?

That is because acne scars do not come in just one form; most of the time, several types are mixed together.

So to achieve proper results, treatment methods that match each type of scar must be applied simultaneously.

How is CLO scar restoration therapy performed?

First, let me explain the chemical treatment, CROSS.

This method precisely delivers a chemical called TCA into the scar area to stimulate the fibroblasts in the dermis.

When fibroblasts become activated, the synthesis of collagen and elastin increases, causing the depressed scar to fill in.

It may be easier to understand if you think of it as filling in a hollow area with soil, like pushing up the scar from the inside.

Next is laser treatment.

A fractional laser is used, and this laser creates thousands of tiny holes in the skin, stimulating the dermal layer and inducing collagen synthesis.

It not only improves acne scars, but also helps reduce pores, leading to better overall skin texture.

Lastly, there is surgical treatment.

Surgical treatments for acne scars include derma abrasion and punch techniques.

Derma abrasion is a procedure that uses a special needle to cut the fibrotic bands that are pulling the skin tissue downward from beneath the scar tissue.

When these bands are cut, the skin that was being pulled downward rises, and the scar is improved.

Gangnam acne scar treatment, why is CLO effective?

The patient asked, "Doctor, then do I have to do all three treatments?"

Yes, that's right. The biggest advantage of CLO scar restoration therapy is exactly this.

In the past, only one treatment method was used, so it was effective only for specific types of scars. When different scar types were mixed, treatment had to be done in several separate sessions.

But because CLO performs multiple treatments at once, it can improve various types of scars all together.

The patient's change, and my hope

"Doctor, now the scars show less even when I wear makeup. I feel more confident when meeting people,"

they said, and I was truly happy to see that.

We see dermatology care not as simple treatment, but as a process of completing your beauty.

Above all, what matters most is naturalness without excess and trust built over time.

Every skin is different. That is why it is important not to rely on a simple procedure, but to provide diagnosis and solutions suited to each person's skin.

▲[Lee Jiham Dermatology Clinic] We provide care in a comfortable and warm atmosphere.

With honest care, verified procedures, and the hands of a specialist, we hope to be a place you can trust for a long time, rather than just one procedure.

To those who are worried about acne scars, I want to say this clearly. Scars do not improve on their own with time.

In fact, if left untreated, they can become deeper and firmer. But if you receive the right treatment at the proper time, they can improve sufficiently.

CLO scar restoration therapy is not simply about hiding scars; it is a treatment that fundamentally improves the skin itself by regenerating it.

To become the name that people think of first when skin concerns arise, we will continue to provide honest and safe care without change.

We hope to solve your skin concerns together with you.
