Microneedling is a minimally invasive skin treatment that uses fine needles to create controlled micro-injuries and stimulate the skin's natural healing response. At Cheongdam JCELL Dermatology Clinic, microneedling for acne scars is planned by a dermatologist according to the type, depth, distribution, and severity of the scars, as well as the patient's skin condition.

Because acne scars can include rolling, boxcar, and other depressed scar types, microneedling is not equally suitable for every scar. Depending on the individual condition, it may be used alone or combined with treatments such as radiofrequency microneedling, laser resurfacing, or other scar-focused procedures.

What Is Microneedling for Acne Scars?

Microneedling uses a device with multiple fine needles to create controlled punctures in the skin. These micro-injuries trigger the body's wound-healing response and encourage the production of collagen and other structural proteins.

As the skin heals, gradual collagen remodeling can help improve the appearance of certain depressed acne scars and uneven skin texture.

Microneedling may be considered for:

• Depressed acne scars
• Uneven skin texture
• Mild to moderate atrophic scars
• Post-acne skin irregularities
• Overall skin smoothness

The treatment is different from simply exfoliating the skin because its main purpose is to stimulate controlled remodeling within the skin.

How Does Microneedling Improve Acne Scars?

Acne scars can develop when inflammatory acne damages collagen and deeper skin tissue. This can leave areas of the skin depressed or uneven after the acne has healed.

Microneedling creates controlled micro-injuries that stimulate the skin's natural repair process. New collagen formation and remodeling may gradually make some depressed scars appear shallower and the surrounding skin more even.

The response varies according to scar type, depth, skin condition, and individual healing characteristics. Microneedling is generally more suitable for certain atrophic scars than for very deep or highly defined scars that may require a more targeted treatment.

Microneedling by a Dermatologist

A dermatologist should first determine whether microneedling is appropriate for the patient's specific acne scars.

The evaluation may include:

• Scar type
• Scar depth
• Skin texture
• Number and distribution of scars
• Skin tone
• Active acne
• Post-acne pigmentation
• Skin sensitivity
• Previous scar treatments
• Previous acne medications

This helps determine the appropriate treatment approach and whether microneedling should be performed alone or combined with another procedure.

Patients with active, painful, or pus-filled acne may need to control the active inflammation before undergoing microneedling.

Microneedling for Rolling Acne Scars

Rolling scars are broad, shallow depressions that can create a wavy appearance across the skin. They may also be associated with fibrous bands beneath the skin that pull the surface downward.

Microneedling may help improve the overall texture and collagen quality around suitable rolling scars. However, when significant tethering is present, microneedling alone may not address the underlying cause of the depression.

In such cases, a dermatologist may consider subcision to release the tethered tissue, followed by or combined with a collagen-stimulating treatment when appropriate.

Microneedling for Boxcar Acne Scars

Boxcar scars are wider depressions with relatively defined edges. Shallow boxcar scars may respond to collagen-stimulating treatments such as microneedling, while deeper or sharply defined scars may require a different approach.

Depending on the scar structure, microneedling may be combined with laser resurfacing or another scar procedure to address both the surface texture and deeper structural changes.

The appropriate treatment depends on the individual scar rather than simply its classification as a boxcar scar.

Microneedling for Deep Acne Scars

Very deep acne scars, including some ice pick scars, may not respond sufficiently to microneedling alone because the treatment works primarily by stimulating broader collagen remodeling.

For narrow and deep scars, a dermatologist may consider more targeted approaches such as TCA CROSS or acne scar surgery. Microneedling may still have a role in improving surrounding texture or addressing additional shallow scars as part of a broader treatment plan.

This is why identifying the depth and structure of individual scars is important before selecting microneedling as the primary treatment.

Radiofrequency Microneedling for Acne Scars

Radiofrequency microneedling combines the controlled micro-injuries of microneedling with radiofrequency energy delivered into the skin.

The added thermal energy can stimulate collagen remodeling at selected depths, making RF microneedling an option for certain acne scars and uneven skin texture.

As with standard microneedling, treatment settings should be customized according to the patient's skin type, scar characteristics, and treatment goals. RF microneedling is not automatically better for every acne scar, so a dermatologist should determine whether it is appropriate.

Combination Treatment for Acne Scars

Many patients have several different acne scar types at the same time. Combining treatments can therefore be considered when one procedure cannot adequately address all of the structural concerns.

Depending on the individual condition, microneedling may be combined with:

• Subcision
• Fractional laser treatment
• Radiofrequency microneedling
• TCA CROSS
• Other scar-focused procedures

For example, subcision may address tethering beneath rolling scars, while microneedling can focus on collagen remodeling and overall texture. Combination treatment should be selected based on the patient's specific scars rather than routinely combining multiple procedures.

Microneedling & Active Acne

Microneedling is generally intended for acne scars after active inflammatory acne has been controlled.

Treating skin with significant active acne may increase irritation and does not address the source of new breakouts. Controlling active acne can also help prevent the formation of additional scars while existing scars are being treated.

Patients should inform their dermatologist about current acne medications and previous procedures because certain treatments may affect the timing or suitability of microneedling.

Microneedling Treatment Process in Seoul

1. Skin & Scar Evaluation

The dermatologist examines the skin to determine the type, depth, and distribution of acne scars and checks for active acne or other skin concerns.

2. Personalized Treatment Planning

Based on the evaluation, the dermatologist determines whether standard microneedling, RF microneedling, or a combination treatment may be appropriate.

3. Microneedling Treatment

The device is used to create controlled micro-injuries at an appropriate depth based on the treatment area and patient's skin condition.

4. Follow-Up

Collagen remodeling takes time, so improvement develops gradually. Follow-up allows the dermatologist to assess the response and determine whether additional sessions or another treatment may be appropriate. Multiple sessions are often needed for acne scar improvement.

Microneedling Results & Recovery

Microneedling does not instantly remove acne scars. Instead, the skin gradually remodels collagen after treatment, which can make suitable depressed scars less noticeable and improve overall texture.

Temporary redness, swelling, sensitivity, or mild peeling can occur after treatment. Recovery varies according to treatment depth, skin sensitivity, and whether another procedure is performed at the same time.

Patients should follow the dermatologist's aftercare instructions and protect treated skin from excessive sun exposure during recovery.

Frequently Asked Questions

Is microneedling good for acne scars?

Microneedling can improve certain depressed acne scars and uneven skin texture by stimulating collagen production. Its effectiveness depends on the scar type, depth, and individual skin condition.

Can microneedling remove acne scars completely?

No acne scar treatment can guarantee complete removal. Microneedling is intended to make suitable scars less noticeable and improve overall skin texture through gradual collagen remodeling.

How many microneedling sessions are needed for acne scars?

The number of treatments varies according to scar severity, treatment depth, skin condition, and individual response. Multiple sessions are commonly needed for progressive improvement.

Is microneedling suitable for ice pick scars?

Very deep and narrow ice pick scars may require more targeted treatments because microneedling alone may not adequately reach or remodel the entire scar. A dermatologist can determine whether microneedling should be combined with another procedure.

Can microneedling treat rolling scars?

Microneedling can improve the texture associated with some rolling scars. If fibrous tethering is contributing to the depression, however, subcision or another treatment may be considered alongside microneedling.

Can I get microneedling while I have active acne?

Significant active inflammatory acne is generally controlled before scar-focused microneedling. This helps reduce irritation and prevents new acne lesions from continuing to cause scars.

What is the difference between microneedling and RF microneedling?

Standard microneedling creates controlled micro-injuries with fine needles, while RF microneedling combines microneedling with radiofrequency energy delivered into the skin. The appropriate option depends on the patient's skin and scar characteristics.

Is there downtime after microneedling?

Most patients can expect temporary redness, sensitivity, swelling, or mild peeling. The exact recovery period varies depending on treatment intensity and individual skin response.

Can international patients receive microneedling for acne scars in Seoul?

Yes. International patients can receive dermatologist-led acne scar evaluation and microneedling treatment in Seoul. Providing information about previous acne treatments, medications, procedures, and skincare products can help with treatment planning.
