Acne Scar Laser + Rejuran: Treatment Guide for Acne Scars

Acne scar laser + Rejuran is a combination treatment approach that may be used to improve acne-scar texture and overall skin quality. Laser treatment can target scar remodeling, while Rejuran is an injectable polynucleotide treatment used to support skin quality and regeneration.

The combination is not a universal solution for every acne scar. Acne scars differ in type, depth, and underlying structure, so treatment should be selected after a medical assessment. Laser resurfacing has an established role in treating certain atrophic acne scars, while evidence for polynucleotide treatments such as Rejuran is still developing.

What Is Acne Scar Laser + Rejuran?

The combination uses two different treatment approaches that may complement each other.

What does acne scar laser treatment do?

Acne scar lasers use controlled energy to stimulate remodeling in scarred skin. Depending on the device, treatment may target the superficial skin layers, deeper dermis, or both.

Fractional laser treatments are commonly used for atrophic acne scars because they create controlled microscopic treatment zones while leaving surrounding tissue relatively intact.

The appropriate laser depends on scar type, skin tone, severity, previous treatments, and the amount of downtime a patient can accept.

What is Rejuran?

Rejuran is a branded injectable treatment based on polynucleotide technology. It is primarily used in aesthetic dermatology for skin-quality improvement rather than facial volume enhancement.

Polynucleotide treatments have been studied for skin regeneration, hydration, elasticity, and scar-related applications. However, research protocols and products vary, and evidence should not be generalized to every treatment marketed under the skin-rejuvenation category.

Why Combine Laser and Rejuran?

The combination may be considered because the two treatments have different roles.

Laser targets scar texture

Laser treatment can be used to improve irregular or depressed skin texture through controlled remodeling.

A 2026 meta-analysis comparing fractional CO₂ laser with microneedling radiofrequency found that both approaches improved post-acne scarring, while fractional CO₂ was associated with more pain and certain post-treatment adverse effects in the analyzed studies.

This illustrates why laser selection and treatment intensity should be individualized.

Rejuran targets skin quality

Rejuran may be incorporated when the treatment plan also aims to improve overall skin quality.

Recent research on polynucleotides and polydeoxyribonucleotides suggests potential benefits for several dermatological applications, but available studies have limitations, including small sample sizes and differences in treatment protocols.

Rejuran should therefore be viewed as a possible component of an acne-scar treatment plan rather than a guaranteed scar-removal treatment.

Which Acne Scars Can Be Treated?

Acne scars are not all the same, and this is one of the most important considerations before treatment.

Rolling scars

Rolling scars are broad depressions that can give the skin an uneven or wavy appearance. They may involve fibrous bands beneath the skin.

Laser treatment may improve their surface appearance, but some patients with significant tethering may need a procedure such as subcision as part of a broader treatment plan.

Boxcar scars

Boxcar scars are depressed scars with more defined edges. Depending on their depth and characteristics, fractional laser treatment may be considered.

Ice-pick scars

Ice-pick scars are narrow and relatively deep. Laser alone may not be sufficient for every patient, and scar-specific procedures may sometimes be considered.

Mixed acne scars

Many patients have several scar types simultaneously. A dermatologist may therefore recommend different treatments for different areas rather than applying one procedure uniformly across the face.

How Is Acne Scar Laser + Rejuran Performed?

The exact treatment sequence varies by provider, laser technology, Rejuran protocol, and patient.

Consultation and assessment

The process should begin with a medical evaluation of:

  • Scar type and depth
  • Skin tone and pigmentation tendency
  • Active acne or inflammation
  • Previous acne-scar treatments
  • Current skincare products
  • Medical history
  • Expected downtime
  • Treatment goals

For patients with a greater tendency toward post-inflammatory hyperpigmentation, laser selection and treatment settings require particular attention.

Laser treatment

The skin is prepared before the laser is applied to the selected areas.

Depending on the laser and intensity, patients may experience heat, stinging, redness, swelling, or temporary sensitivity.

A more aggressive resurfacing laser can produce more visible recovery than a less intensive treatment.

Rejuran treatment

Rejuran is administered through multiple small injections or another product-specific technique.

Temporary redness, swelling, tenderness, and small raised areas at injection sites can occur.

Laser and Rejuran may be performed during the same treatment plan, but they do not necessarily need to be performed during the same appointment.

How Many Sessions Are Needed?

There is no standard number of sessions for acne scar laser + Rejuran.

The required number can depend on:

  • Scar severity
  • Scar type
  • Laser technology
  • Treatment intensity
  • Skin response
  • Whether other procedures are required

Research studies use different treatment schedules. For example, some acne-scar laser studies have evaluated multiple sessions separated by several weeks. These study protocols should not be interpreted as a universal prescription for individual patients.

A provider should explain the proposed treatment schedule during consultation.

Results and Recovery

Acne-scar improvement is usually gradual rather than immediate.

What results can you expect?

Depending on the treatment plan, patients may notice improvements in:

  • Uneven skin texture
  • Visibility of some depressed scars
  • Overall skin smoothness
  • Skin quality
  • Hydration or elasticity

The degree of improvement depends heavily on scar morphology. Deep or structurally tethered scars may remain visible even after multiple treatments.

How much downtime is there?

Downtime depends largely on the laser used and the intensity of treatment.

Possible short-term effects include:

  • Redness
  • Swelling
  • Warmth or sensitivity
  • Peeling
  • Crusting with some resurfacing lasers
  • Temporary pigmentation changes

Fractional CO₂ laser can involve more noticeable downtime than some less aggressive technologies. Patients should allow adequate recovery time before important events or international travel.

Risks and Limitations

Neither laser treatment nor Rejuran is risk-free.

Laser treatment can cause prolonged redness, pigmentation changes, infection, burns, or scarring. Risk depends on the device, settings, skin type, treatment technique, and aftercare.

Rejuran injections may cause temporary swelling, redness, tenderness, or bruising. Injectable procedures can also have rare but serious complications, so they should be performed by an appropriately qualified medical professional.

The biggest limitation is that acne scars cannot always be completely removed. Treatment generally aims to reduce their visibility and improve skin texture rather than restore scarred skin completely to its original condition.

How Much Does Acne Scar Laser + Rejuran Cost in Seoul?

There is no universal price for acne scar laser + Rejuran in Seoul.

The treatment cost may depend on:

  • Laser type
  • Treatment intensity
  • Number of areas treated
  • Number of sessions
  • Amount of Rejuran used
  • Provider and facility
  • Consultation
  • Aftercare
  • Additional scar treatments

International patients should also separate treatment costs from medical-tourism expenses such as accommodation, transportation, medication, and follow-up.

Before booking, request an itemized quotation that identifies the exact laser, Rejuran product, treatment areas, and number of sessions included.

Is Acne Scar Laser + Rejuran Right for You?

The combination may be considered when acne-scar texture is accompanied by concerns about overall skin quality.

However, it is not automatically appropriate for every patient.

A consultation should determine whether the primary concern involves:

  • Depressed acne scars
  • Fibrous tethering
  • Uneven pigmentation
  • Enlarged pores
  • Active acne
  • General skin-quality concerns

Patients researching this combination can also explore acne scar treatment options before deciding which approach is most appropriate.

Questions to Ask Before Treatment

Before booking, consider asking:

  1. What type of acne scars do I have?
  2. Which laser technology will be used?
  3. Why is this laser suitable for my skin?
  4. What role will Rejuran play in my treatment plan?
  5. Will the laser and Rejuran be performed on the same day?
  6. How much downtime should I expect?
  7. How many sessions may be recommended?
  8. What side effects are most relevant to my skin type?
  9. Could another procedure, such as subcision, be more appropriate for some scars?
  10. What follow-up is available if I am an international patient?

Frequently Asked Questions

Can Rejuran remove acne scars?

Rejuran should not be described as a treatment that completely removes acne scars. It may be included in a broader plan to improve skin quality, but treatment selection depends on the type and depth of scarring.

Is laser alone enough for acne scars?

It can be helpful for some acne scars, but not every scar responds equally. Deep, tethered, or narrow scars may require other scar-specific procedures.

Can laser and Rejuran be done together?

They can be combined in some treatment plans, but the timing should be determined by the treating medical professional based on the specific laser, product, skin condition, and recovery requirements.

How long does it take to see results?

Improvement is generally progressive because collagen remodeling and skin healing take time. The timeline varies according to the treatment, number of sessions, scar severity, and individual response.

Is there downtime after acne scar laser and Rejuran?

Yes. Laser treatment can cause redness, swelling, peeling, or crusting depending on the technology and intensity. Rejuran injections may cause temporary swelling, redness, tenderness, or bruising.

Conclusion

Acne scar laser + Rejuran combines a treatment focused on scar remodeling with an injectable treatment intended to support skin quality. Laser treatment has an established role for certain types of atrophic acne scars, while evidence surrounding polynucleotide treatments continues to develop.

For patients considering this combination in Seoul, the most important step is to identify the actual scar type and understand what each component of the treatment is intended to accomplish. A qualified medical assessment can help determine whether laser, Rejuran, another scar procedure, or a combination approach is appropriate.
