Fractional Laser Resurfacing in Seoul.
A closer look at the fractional laser platform (Matrixell Pro) behind several of LOUAVE Dermatology Clinic's pore, texture and scar-related pages — including Pore Treatment, Acne Scar Treatment and Scar & Stretch Mark Revision. Rather than treating the whole surface at once, the laser delivers energy through a grid of microscopic treatment zones separated by untouched skin, so depth and density are matched to your specific concern rather than applied the same way for everyone.
This page focuses on the fractional laser platform itself. LOUAVE also publishes concern-specific pages that use this technology — including Pore Treatment, Acne Scar Treatment and Scar & Stretch Mark Revision — along with CO2 Laser Treatment for readers comparing precision ablative resurfacing.
Platform Overview
Shallow, low-density passes for texture and pore refinement, through to deeper, higher-density passes for structural scarring.
Most pore, texture and scar-focused courses are delivered as a spaced series, reviewed and adjusted as the skin responds.
The doctor selects the depth and density for your specific goal at consultation, rather than applying one standard setting to every patient.
Understanding The Platform
One laser, several distinct depths it's actually used at.
"Fractional" describes how the energy is delivered, not a specific wavelength. Rather than treating the entire surface in one continuous pass, the laser creates a grid of microscopic treatment columns through the outer skin layers, each surrounded by untouched tissue. Those untouched bridges speed re-epithelialisation, which is why fractional resurfacing generally heals faster than a fully continuous, full-field pass.
Matrixell Pro operates in the fractional non-ablative range, similar to the class of platforms commonly used for pore, texture and scar resurfacing. Depth and treatment density are adjusted at consultation — shallower, lower-density passes for surface texture, deeper, higher-density passes where structural scarring is the target.
Because one platform can be used several different ways, the depth and density are chosen at consultation based on what's actually being treated — enlarged pores, atrophic acne scarring, settled surgical or stretch-mark scarring, or general textural refinement without a specific structural target.
Matrixell Pro is not the only technology LOUAVE uses for pore, texture and scar concerns. Potenza microneedling RF delivers energy beneath the surface via insulated needles rather than resurfacing the surface itself, and N-Pulse CO2 is considered separately for deeper, more targeted ablative resurfacing — which platform is proposed depends on the confirmed pattern, not assumed in advance.
Match the depth to the layer that needs to change, not the other way round.
The depth, density and number of passes used in your session follow from what's being treated — pore size, scar depth and skin thickness — rather than a single default setting applied to every patient.

The Four Depths, Explained
Depth 01
Depth 02
Depth 03
Depth 04
Same laser, four different depths it gets used at.
During consultation, the doctor reviews the concern being treated and proposes one or more of the depths below — sometimes a single depth across a course, sometimes a combination planned together with another technology.
Superficial Texture Pass
Shallow, low-density passes aimed at dull tone and fine surface texture, with minimal downtime and the fastest recovery of the four depths.
Pore & Texture Refinement
Mid-depth, moderate-density passes used for enlarged, visible pores and general textural unevenness across the cheeks and T-zone.
Scar-Focused Resurfacing
Deeper, higher-density passes for atrophic acne scarring or settled textural scarring, matched to the confirmed scar pattern.
Combined Fractional + RF Planning
For deeper or more established scarring, fractional passes may be sequenced with Potenza microneedling RF as part of a layered plan.
What Fractional Laser Resurfacing Is Used For
Concerns matched to a depth, not treated identically.
The concerns below give a sense of how this platform is applied at LOUAVE. Each concern has its own dedicated page with condition-specific detail — this page focuses on the underlying technology shared across them.
Enlarged, Visible Pores
Stretched or oil-driven pores across the nose and cheeks are refined with mid-depth passes, often as an alternative or complement to microneedling RF.
Pore & Texture DepthIcepick, Boxcar & Rolling Acne Scarring
Depressed acne scarring is treated with deeper, scar-focused passes matched to the confirmed structural pattern, often alongside Potenza.
Scar-Focused DepthSettled Surgical or Stretch-Mark Scarring
Mature, white or silvery textural scarring that has already passed the vascular stage is resurfaced with scar-focused fractional passes.
Scar-Focused DepthDull Tone & General Texture
Where there's no specific pigment or scar target and the goal is a brighter, smoother complexion overall, the superficial pass is considered instead.
Superficial Texture PassFine Lines & Early Textural Aging
Superficial fine lines and early loss of surface texture may respond to a fractional course, considered alongside other rejuvenation options.
Superficial Texture PassCombination Planning With Other Technologies
Deeper or mixed-pattern scarring is sometimes planned across fractional laser, RF microneedling and precision CO2 together, reviewed individually.
Multi-Technology Planning Treatment Philosophy
Choose the depth deliberately, not the same setting for everyone.
Because one platform can be used several different ways, the approach begins with matching depth and density to the concern in front of the doctor, rather than running one standard protocol for every patient.
Depth Selected at Consultation
Pore pattern, scar depth, skin type and treatment goal are reviewed together before a depth — superficial, mid-depth or scar-focused — is proposed, rather than defaulting to one setting.
Concern reviewed before depth is chosen
No default or one-size setting
Individualised, not formulaic
Skin type and history reviewed before treatment
Preferred focus: depth-matched, realistic planning
Lower Density Where That's the Safer Path
For thinner or more reactive skin, lower-density passes repeated over a staged course are preferred over one aggressive session, reducing the risk of prolonged redness or textural change.
Sessions spaced to suit the concern
Reviewed before further sessions
Settings adjusted rather than escalated by default
Additional sessions expected for established scarring
Assessment focus: deliberate, staged resurfacing
Honest About What One Platform Can't Do
Fractional laser resurfacing is not the right tool for every pore, every scar, or every structural concern. Where RF microneedling, precision CO2, or a non-laser option would serve you better, that's discussed openly rather than defaulted to.
Realistic expectations set upfront
Not presented as a fix for every concern
Referral to other options discussed openly
Individual results still vary
Safety focus: honest expectation-setting
LOUAVE Treatment Process
A structured plan built around the right depth for you.
The process below applies across Matrixell Pro's different depths, from initial concern review through to depth selection, sessions, and ongoing course planning.
Consultation & Concern Review
The doctor examines pore pattern, scar depth, skin type and treatment goal to determine which of the platform's depths is actually appropriate.
Concern-first assessmentDepth & Density Selection
Depth, treatment density and whether a combination with RF microneedling is planned are set based on the chosen approach, along with an approximate session count.
Depth-specific planningTreatment Session(s)
Passes are delivered according to the selected depth, usually as a spaced course of 3–6 sessions for pore, texture and scar-related concerns.
Depth-appropriate deliveryProgress Review & Course Planning
Response is reviewed after each session, with further sessions or a depth change planned based on how the area is responding.
Ongoing progress review Results & Development
Day 0
Days 1–4
Weeks 4–6
Ongoing
What to expect depends on the depth used.
A superficial texture pass tends to give a visible, near-term smoothing effect with minimal downtime, while scar-focused passes build gradually over a staged course. Both are reviewed against the timeline the doctor sets out at consultation, since expectations differ by depth.
Treatment session
Passes are delivered according to the selected depth; mild redness and pinpoint warmth in the treated zones are common immediately afterward.
Immediate effects settle
Redness and any mild flaking or peeling typically settle within a few days; a superficial pass's smoothing effect is often visible from this point.
Review & next session, if planned
For scar-focused courses, response is reviewed at the next visit and depth or density adjusted before the following session.
Course completion & maintenance
Once a scar-focused course is complete, sun protection helps preserve results; superficial passes are sometimes repeated periodically for maintenance.
International patients planning a multi-session course should discuss a realistic schedule with the clinic, since sessions are typically spaced four to six weeks apart.
Suitability & Screening
Suitability is confirmed through an honest health review.
Treatment may be modified, delayed or declined when certain health factors are present, or when your concern is better addressed with a different platform or approach.
Fractional laser resurfacing may be discussed when:
- You have a pore, texture or scar-related concern — enlarged pores, atrophic acne scarring, or settled surgical or stretch-mark scarring.
- You're able to attend the sessions the chosen depth requires, typically a course of 3–6 sessions spaced weeks apart.
- Your skin has not had a recent aggressive laser, peel or procedure that could increase treatment risk right now.
- You understand that scar-focused passes work gradually and results build over a course, not in one session.
- You accept that some concerns may be better matched to a different technology, such as RF microneedling or precision CO2.
Tell the doctor before treatment about:
- Pregnancy, planned pregnancy or breastfeeding.
- Current or recent use of isotretinoin, hormonal medication, or other photosensitising drugs.
- A history of keloid scarring, cold sores, or active skin infection in the treatment area.
- Active inflammatory acne breakouts in the area being considered for scar-focused resurfacing.
- Any previous laser, RF microneedling, or ablative treatment in the area, including outcomes and whether healing was delayed.
Aftercare
Simple care, matched to the depth used.
Follow the specific instructions provided by the treating doctor after each session, since aftercare details differ slightly between superficial, mid-depth and scar-focused passes.
Strict Daily Sun Protection
Apply broad-spectrum SPF daily and limit direct sun exposure, both while healing and afterward, to protect results across every depth.
Keep Skincare Gentle for a Few Days
Avoid strong actives, exfoliants or fragranced products on the treated area until any mild redness or flaking has fully settled.
Don't Pick at Flaking Skin
Mild flaking or pinpoint crusting after a pass should be left to shed naturally — picking can affect how evenly the skin resurfaces.
Attend the Review Visit
Attend the follow-up review so the doctor can confirm healing and decide whether a further session or a depth change is appropriate.
Safety Information
General information, not a substitute for consultation.
This page provides general educational information about the fractional laser platform. It does not replace an individual medical consultation, and effects, recovery and suitability vary between patients and between depths.
Seek prompt attention for:
- Pigment that appears markedly darker or more widespread than expected in the weeks after a session, rather than settling on its own.
- Blistering, crusting, or open skin breakdown at the treated area, beyond expected mild redness or pinpoint flaking.
- Signs of infection, including increasing pain, warmth, discharge or fever at the treated area.
- Persistent burning, unusual pain, or textural change that does not settle within the expected timeframe for the depth used.
- Any allergic reaction to topical products used as part of the treatment or aftercare, such as significant redness, swelling or itching.
Any sign that the treated area is not healing as expected should be reported to the clinic promptly rather than waiting for the next scheduled review. Adjusting the depth or density for future sessions is often the right response to protect the skin's long-term outcome.
Frequently Asked Questions
Questions about the fractional laser platform.
Depth selection, session count, expected timelines and combination planning are confirmed during consultation.
What is fractional laser resurfacing?
Fractional laser resurfacing delivers energy through a grid of microscopic treatment zones separated by untouched skin, rather than treating the whole surface at once. At LOUAVE, this is the Matrixell Pro platform, used across several pore, texture and scar-related pages.
Is the treatment the same for every concern?
No. The doctor selects a depth — superficial, mid-depth, or scar-focused — and density based on what's actually being treated. It is not applied the same way for every patient or every concern.
What's the difference between fractional laser and RF microneedling (Potenza)?
Fractional laser resurfaces the skin's surface layer through a grid of light-energy zones. Potenza microneedling RF delivers energy beneath the surface via insulated needles without resurfacing the top layer. The two work by different mechanisms and are sometimes sequenced together for deeper concerns.
How many sessions are usually needed?
It depends on the depth. A superficial texture pass may be done as an occasional single session, while scar-focused courses are typically delivered as 3–6 sessions spaced four to six weeks apart.
Does fractional laser resurfacing hurt?
Most patients describe a warm, prickling sensation during treatment. Topical numbing cream is typically applied beforehand for mid-depth or scar-focused passes, and sensitivity can vary by area and depth.
What is the downtime after treatment?
Downtime is typically minimal to moderate depending on depth — mild redness or pinpoint flaking for a few days is common, and most patients return to normal activities within one to a few days.
Can fractional laser treat very deep scars?
Deeper scar-focused passes can meaningfully improve moderate atrophic scarring, but very deep icepick scars sometimes respond better to a combination approach, or to precision CO2 treatment. This is assessed individually rather than assumed in advance.
Is this the same as CO2 Laser Treatment?
No. Matrixell Pro is a fractional non-ablative-range platform, while N-Pulse CO2 is a precision ablative laser used more selectively for deeper, targeted resurfacing. Both can address scarring, and which one is proposed depends on scar depth and pattern, confirmed individually at consultation.
How soon are results visible?
A superficial texture pass's smoothing effect is often visible within a few days of a single session. Scar-focused results build more gradually, typically becoming noticeable over several sessions of a staged course.
Can fractional laser treatment be combined with other treatments?
Yes. It's often planned alongside Potenza microneedling RF or precision CO2 where deeper structural scarring is also a concern, or sequenced with a skin booster for overall skin quality. Combination planning is confirmed together at consultation.

Since some depths are single-session and others need a course spaced weeks apart, the doctor will help confirm a schedule that fits your trip.
Important treatment information
This page provides general educational information about the fractional laser platform and does not replace an individual medical consultation. Fractional laser resurfacing runs at several distinct depths — superficial, mid-depth and scar-focused — and the depth, density and number of passes used affect both expected results and recovery; not every depth or concern responds the same way, and some scar patterns may respond better to a different technology or a combination approach. Treatment must be planned by an appropriately experienced medical professional after reviewing pore or scar pattern, skin type, sun exposure history, previous laser or RF treatments, health history, medications, allergies and informed consent. Temporary effects may include mild redness, warmth or pinpoint flaking in the treated area, which typically settles within a few days of each session. Other possible effects include post-inflammatory hyperpigmentation, incomplete improvement requiring further sessions, or, uncommonly, patchy textural change. Rare but serious complications include blistering, burns, infection, unexpected scarring or textural change, and allergic reactions to topical products used during treatment or recovery. Seek prompt medical advice for pigment that becomes markedly darker or more widespread than expected, blistering or skin breakdown, signs of infection, or symptoms of a significant allergic reaction. Daily sun protection is recommended both during healing and afterward, and results, session count, onset, and long-term stability vary by individual and cannot be guaranteed.
