[Lee Yudeuk, Dermatology Specialist]

Hello,

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

This is Leejham Dermatology Clinic.

Many people may feel uncomfortable because of the uneven marks left on their faces. Your acne has healed, but the pitted traces on your skin remain and cannot even be covered with makeup, so you may be worried. In fact, what hurts the heart longer than acne itself is scars.

Today, I’d like to share practical information for those with concerns like these, including acne depressed scar laser treatments.

A beauty consultation that is truly "beneficial"

I’m dermatologist Lee Yudeuk.

Every time you look in the mirror, confidence fades away

Among those troubled by scars, there are cases in the mid-20s who have deep pitted scars on both cheeks and the forehead from acne that began back in school.

In such cases, you may experience reduced confidence in social interactions, roughness on the skin surface that cannot be concealed even with makeup, and a problem that becomes even more noticeable under strong lighting.

There are also many cases where people become reluctant to take photos because of their skin condition.

Why pitted scars form

Acne depressed scars are medically called atrophic scars.

They occur when inflammation from acne damages deep into the dermis layer of the skin, leaving the skin surface sunken in as if the ground has collapsed.

If you squeeze acne by hand or if the inflammation was severe, deeper scars may remain.

The shapes of scars also vary, and many people have a combination of types such as ice pick scars that look as if they were punched with an awl, boxcar scars with round bowl-like shapes, and rolling scars that appear broadly indented like waves.

The reason these scars form is that collagen is abnormally rearranged during the skin’s healing process.

In normal skin, collagen fibers should be closely interwoven like a net, but the area damaged by inflammation loses this structure, causing the skin to be pulled downward.

A combined approach including acne pitted scar laser treatment

At Leejham Dermatology Clinic, we use a comprehensive approach called CLO.

It is a method that applies Chemical, Laser, and Operational methods at the same time to address various types of scars.

The chemical method is also called CROSS, and involves applying a chemical agent called TCA directly to the scar area.

This agent stimulates fibroblasts in the dermis to promote increased synthesis of collagen and elastin.

You can think of it as similar to filling in sunken ground with soil.

For acne pitted scar laser treatment, we use fractional lasers.

Our clinic has various devices such as PICO fractional, Secret, and Tixel. These lasers create thousands of microscopic holes in the skin and stimulate the dermal layer.

In this process, the skin’s natural ability to normalize itself is activated, encouraging new collagen production and positive changes in scars.

It can also help with pore-related changes, so it may be considered as part of overall skin texture management.

For surgical methods, we use subcision and punch techniques.

In the case of deeply pitted ice pick scars, we carry out a procedure that uses a needle to cut the fibrotic bands beneath the scar tissue that pull the skin downward.

This method helps the skin lift upward.

These three methods are combined according to the type and depth of scars of the person who visits us, and depending on the individual, several sessions may be necessary.

Scar prevention and daily care

Acne pitted scar laser care is important, but it is even more important to prevent scars from forming in the first place.

When acne appears, never squeeze it by hand.

Bacteria on your hands can worsen the inflammation and can damage the dermis.

If your acne is severe, getting an early examination at a dermatology clinic and starting an appropriate method can be the first step toward preventing scars.

After receiving treatment, steady effort is needed.

Adequate hydration is especially important, and you should drink more than 2 liters of water a day and apply moisturizer carefully in the morning and evening.

If the skin becomes dry, regeneration slows down and scars can become deeper.

Sunscreen is also essential.

Ultraviolet rays can cause pigmentation in scar areas and interfere with the skin’s normalization, so we recommend using a product with SPF 30 or higher even indoors.

Choosing basic skincare products is also important.

Avoid products that are excessively oily, and it is good to use moisturizers containing ceramides or hyaluronic acid.

Also, vitamin C serums can help collagen production and may aid scar care, so please consider using them consistently.

Understanding the process

Scar care varies from person to person, and multiple sessions may be needed.

It may be difficult to achieve perfectly flat skin, but you may experience overall changes in skin condition.

It is important to maintain healthy skin by receiving regular skin care.

A sincere word

Considering skin care that includes acne pitted scar laser treatment is not simply about changing your appearance.

It can be a process of regaining lost confidence and being able to face the world more boldly.

At Leejham Dermatology Clinic, we strive to provide diagnoses and solutions suited to each person’s skin.

Based on understated naturalness and long-standing trust, we want to be with you in the process of completing your beauty.

If you are worried about scars, please do not suffer alone for too long; consult a doctor.

We sincerely hope this helps with your skin concerns, and that when you stand in front of the mirror every morning, you can greet the day with a happy smile.
