💥 Acne Scars: Things You Must Know Before Laser Treatment

Acne Scar Treatment Methods and Laser Guide from a Dermatology Specialist

Hello, this is Yonsei Bombit Dermatology.

Acne often subsides naturally over time, but scars do not easily go away.

In particular, sunken scars or thick, pore-like scars can make the skin texture look rough and even make the overall impression appear dull.

Today, for those considering laser treatment for acne scars, I will summarize the key points you should know before the procedure.

Acne Scar Treatment Methods and Laser Guide from a Dermatology Specialist

1️⃣ Acne scars: Do treatment methods differ depending on the type?

Treatment approaches vary depending on the shape and depth of the scar.

• Ice pick scars (narrow, deep scars)

• Rolling scars (broad, shallow, uneven scars)

• Boxcar scars (wide, angular scars)

• Pore-like scars (scars that appear like widely spread pores)

Customized treatment suited to each scar type is necessary.

Yonsei Bombit Dermatology provides tailored solutions by scar type.

2️⃣ Do ice pick scars require special treatment?

Deep and narrow scars like ice pick scars are difficult to improve satisfactorily with laser treatment alone.

In such cases, the CROSS method is used.

The CROSS method is a treatment in which high-concentration TCA (trichloroacetic acid) is applied drop by drop to the scar area to induce collagen regeneration.

✔ Stimulates the base of the scar to induce new collagen formation

✔ Gradually fills in deep scars to help achieve a more natural improvement

📍 It is especially effective for narrow, deep ice pick scars.

3️⃣ How are deep and broad scars treated?

A technique called subcision is used.

Subcision is a method that uses a special needle to break the adhesions at the base of the scar.

✔ Deep, broad depressed scars

✔ Scars with a firmly attached base

In such cases, subcision can

lift the scar and smooth the surface.

📍 At Yonsei Bombit Dermatology, the range and depth of the incision are precisely adjusted to the skin condition.

4️⃣ Which laser is used to treat scars?

At Yonsei Bombit Dermatology, customized treatment is provided by combining various lasers and techniques depending on the type of scar.

• Fractional laser (using CICU)

It creates microthermal damage in deep scars such as boxcar scars to promote collagen regeneration and improve skin texture.

• Pico MLA

Effective for shallow, uneven rolling scars.

A picosecond laser is delivered through a Micro Lens Array to evenly refine the skin surface and create natural smoothness.

• Pinhole method (using CO2 laser)

A method that treats wide scars or raised scars by making small holes with a CO2 laser.

It is excellent for gently softening scars.

• Fractional radiofrequency treatment (3DEEP FSR)

Used for stretch marks or widely spread depressed scars.

It delivers energy deep into the skin to improve elasticity and skin texture.

• Secret RF

Used for thick pore-like scars.

It delivers radiofrequency to the dermis through micro-needles, simultaneously promoting pore tightening and improved skin elasticity.

5️⃣ How many treatment sessions are needed?

Scar treatment is not completed in just one session.

• Usually, three to five or more repeated treatments are needed.

• Treatment is carried out at 4- to 6-week intervals, allowing enough time for skin regeneration.

As collagen gradually fills in, the skin recovers with a more natural and smoother texture.

6️⃣ What should be注意 after treatment?

After acne scar laser treatment,

temporary skin reactions may occur.

✔ Redness, swelling, and scabbing may occur

✔ Be diligent with sun protection

✔ Avoid excessive irritation to the skin

🧴 In closing

Acne scar treatment does not end with just one strong laser session.

It requires accurate scar analysis, selection of the right customized technique, and consistent treatment and care.

Yonsei Bombit Dermatology provides individualized scar treatment by combining the CROSS method, subcision, CICU fractional laser, Pico MLA, CO2 pinhole method, 3DEEP FSR radiofrequency, and Secret RF.
