Precise treatment
at the depth of each scar
with an erbium laser

ProFractional is used on Sciton's JOULE platform. The 2940 nm Er:YAG laser creates closely spaced microscopic channels in the skin. Treatment depth can be adjusted precisely from 25 μm to 1,500 μm to match each scar.

Precise, even removal of scar tissue stimulates dermal fibroblasts to produce more collagen and new skin tissue. Er:YAG energy is readily absorbed by water, limiting heat spread beyond the target. This tends to reduce discomfort, redness and the risk of pigmentation.

Acne scars, surgical scars, pores: what this laser improves

Acne Scars

Softens indented acne scars. Microscopic channels reach the scar's depth, then fill with new collagen to smooth the scar edges.

Surgical and injury scars

Blends scar lines from surgery or injuries into the surrounding skin. Research has reported improved texture, color and redness in surgical scars after 3 sessions at monthly intervals.

Burn scars

Evens out irregular burn-scar surfaces. Different depths are used for each area over a series of sessions.

Enlarged pores

Makes enlarged pores look tighter. Increased dermal collagen provides firmer support around each pore.

Texture and tone

Smooths rough, uneven texture and gives dull skin a brighter, more even tone.

Fine lines

Softens fine lines around the mouth, eyes and between the brows. Increased collagen production makes the skin firmer.

Scar treatment planned by your doctor
Treatment by a doctor who teaches scar laser therapy

Results depend on how treatment is planned and performed. We take time with every patient. A doctor handles your consultation and performs your treatment personally.

  1. A separate depth for each scar

    Acne, surgical and burn scars differ in depth and shape. Your doctor examines each scar and selects the laser depth and treatment density for that area.

  2. Care from a doctor who lectures on scar lasers

    Dr. Chang-Hwan Cho has lectured at ASLS conferences on scar treatment and aftercare following scar laser procedures. In 2019, a Sciton vice president and international instructor visited the clinic to discuss treatment programs.

  3. Combining treatments for your scars

    We also offer Sciton's HALO and BBL Forever, along with UltraPulse, Discovery PICO and Opus for scar treatment. Your doctor chooses a combination according to scar shape and skin condition.

Could a fractional scar laser help your scars?
Your doctor will assess whether it is right for you

  • You want to improve indented acne scars
  • Scars remaining after surgery bother you
  • You have scars from an injury
  • You want to improve burn scars
  • You have keloid scars; your doctor first assesses whether treatment is appropriate for your skin's healing tendency
  • You want to reduce the appearance of enlarged pores
  • Rough texture and fine lines are both concerns

ProFractional and CO2 lasers:
Wavelength affects discomfort and redness

ProFractional and the CO2 fractional lasers commonly used for scars operate at different wavelengths.

TypeWavelengthWater absorptionAfter treatment
Conventional fractional CO2 laser10,600nmBaselineHeat tends to spread farther into surrounding tissue
JOULE ProFractional2,940nmAround 10 times that of CO2Less surrounding thermal damage, with generally less pain and redness

How the laser smooths scars
Your doctor explains how it works

How does the laser fill scars? The process of creating microscopic channels and filling them with new tissue has four stages. A doctor who teaches scar laser therapy selects the depth and density for each scar.

Illustration of the skin and underlying tissue
  1. Setting the depth

    Laser depth and treatment density are matched to the scar.

  2. Microscopic channels

    A computer-controlled scanner creates precise, evenly distributed channels.

  3. Collagen renewal

    Stimulated fibroblasts produce new collagen to fill the scar.

  4. Faster healing

    Healthy skin between the channels helps the treated areas heal quickly.

  3. Apply sunscreen carefully whenever you go outdoors for 4 weeks after treatment.
  4. Avoid hot environments such as saunas and steam rooms for 1–2 weeks.

Scar laser treatment: results, downtime and sessions
Answers from our doctors

How do I choose a JOULE ProFractional clinic in Apgujeong, Gangnam, Seoul?

This laser requires depth and density to be adjusted for each scar, so treatment planning affects results. Check whether a doctor diagnoses the scars and performs treatment personally, and whether other scar treatments can be combined when needed. We take time with every patient, with a doctor leading both consultation and treatment.

Which scars can ProFractional improve?

It treats acne scars and scars from surgery, injuries and burns, while also addressing enlarged pores, rough texture and fine lines. As new collagen fills the microscopic channels, scars gradually become shallower. Manufacturer materials describe continued improvement for up to 6 months after treatment.

How does ProFractional differ from a fractional CO2 laser?

Both are ablative fractional lasers that create microscopic channels in the skin. ProFractional's 2940 nm wavelength is absorbed by water much more readily than CO2 energy, so less heat spreads beyond the target. Analyses combining comparative studies have also found lower pain scores and shorter-lasting redness with fractional Er:YAG lasers.

Does ProFractional hurt?

Numbing cream is applied first, so discomfort is usually manageable. Sedation can also be discussed when treating extensive, deep scars.

What are the downtime and side effects?

Skin may look red and feel hot, like sunburn, immediately afterward. Mild swelling or itching may appear the next day and usually settles within 3–5 days. Manufacturer materials state that makeup can be applied after 24 hours, usual activities can resume in 1–2 days, and full recovery takes around a week. Let any scabs fall off naturally.

How many sessions will I need, and how long do results last?

Manufacturer materials generally recommend 1–4 sessions and describe the best results with an initial series of 2–4. For acne scars, courses of 4–5 sessions about a month apart have been described. Early changes appear after 3–5 days, and results last 6–12 months. Your doctor selects the number and interval according to your scars.
