UltraPulse delivers narrow, powerful CO₂ laser columns deep into the dermis to remodel disorganized scar collagen. From acne scars to surgical and burn scars, your doctor selects the mode according to each scar’s depth.
Every scar has its own shape and depth. Even with the same device, we select the mode and depth separately for each one.

UltraPulse is Lumenis’ fractional CO₂ laser. A fractional scanner directs narrow, high-energy columns into the dermis, building on the UltraPulse technology previously used for ablative resurfacing. Our clinic uses UltraPulse Encore with SCAAR FX for scar treatment under the name Scar Impact UltraPulse.
According to our clinic’s treatment materials, a single session may provide effects comparable to three or more conventional fractional CO₂ sessions, with less discomfort and a lower risk of post-treatment pigmentation. Results depend on the scar and treatment settings.
Narrow laser columns reach the base of rolling, boxcar and ice-pick scars, disrupting disorganized collagen and stimulating new collagen to reduce their depth.
Makes surgical and traumatic scars smoother and more even in color. Deep, thick scars can be treated with SCAAR FX, the deepest-reaching mode.
Softens and smooths firm burn scars. In a study of 11 patients treated over ten sessions, all had improved scar scores and new collagen in the upper dermis.
New collagen supports the tissue around pores, reducing the enlarged appearance that can accompany scarring.
Your doctor selects broad, shallow ActiveFX or narrow, deeper DeepFX treatment according to wrinkle depth.
New collagen forms as the skin recovers, improving rough texture and firmness.
Results depend on planning and technique. At Dong-An Joongsim Clinic, a doctor conducts your consultation and performs the procedure, with time to assess your individual scars.
The laser offers ActiveFX, DeepFX, TotalFX and SCAAR FX modes. Your doctor assesses scar shape, depth and skin type before choosing the mode, depth and number of sessions.
Dr. Matteo, an international UltraPulse Encore key opinion leader and scar-treatment specialist, visited the clinic to share techniques. He also discussed clinical practice with Drs. Cho and Koo in 2018.
Dr. Koo lectured on UltraPulse scar treatment at the ASLS autumn conference in 2015. At the 2023 spring conference, Dr. Cho discussed UltraPulse in the context of international scar-treatment consensus guidance.
I’ve seen a real improvement after three sessions
I had three sessions of UltraPulse laser and pulse toning for acne scars, and I’m seeing a real difference… My scars are only on my cheeks and temples, so I didn’t have my whole face treated. That may be why it didn’t hurt with just numbing cream.
Your doctor chooses among four laser modes according to the shape and depth of your scars.
| Modes | Method | Best suited to |
|---|---|---|
| ActiveFX | Broad, shallow treatment with a 1.3 mm beam | Fine lines, texture and uneven skin tone |
| DeepFX | Narrow, deep treatment with a 0.12 mm beam | Wrinkles and scars |
| TotalFX | ActiveFX and DeepFX combined | Superficial and deeper layers in one treatment |
| SCAAR FX | 0.12 mm beam; up to 4 mm in a single pulse | Deep, prominent and complex scars |
How can depressed scars improve? Narrow laser columns remodel the collagen within them. A doctor who teaches scar treatment at Korean and international conferences plans the depth for each scar.
Narrow, powerful CO₂ beams create small channels deep in the dermis.
Each pulse ends before much heat spreads sideways, limiting damage to surrounding skin.
Disorganized scar collagen is disrupted and replaced with newly organized collagen.
The narrow columns leave surrounding skin intact to support faster healing.
Our approach
Your doctor assesses scar shape, depth and skin type before choosing the laser mode and depth and deciding whether to add Shin Nanoskin.
Compare treatments for pigmentation and scarring using the same criteria. The most appropriate option depends on your skin and is chosen with your doctor.

Patients visit before filming, weddings, presentations and other important dates. Your doctor plans the timing and combination around your schedule and scar condition.
If your event is tomorrow
Allow plenty of recovery time before an important event. If the date is too close, we may recommend a treatment with no downtime instead.
If your event is a month away
We work back from your event date to plan treatment and recovery. Our range of devices allows us to choose a combination suited to your skin.
Your doctor handles both your consultation and treatment. A patient coordinator can help with pricing.
Your doctor examines the shape and depth of your scars.
Topical anesthetic helps reduce stinging during treatment.
The laser mode is selected to match scar depth.
Stem-cell-based care and a protective dressing may be added to support recovery.

Our doctors explain acne scars, stretch marks and pores in clear, practical terms.
Depressed acne scars fall into three main types: ice pick, rolling and boxcar. Each responds to a different combination of lasers and other treatments.
The doctors at Dong-An Joongsim Clinic
Red stretch marks are an early stage with visible vessels and inflammation. White stretch marks are a later stage of thinned, scarred dermis, so treatment differs.
The doctors at Dong-An Joongsim Clinic
To reduce the appearance of enlarged pores, first identify the cause: excess oil, loss of firmness or the size of the hair follicles.
The doctors at Dong-An Joongsim ClinicWith this laser, choosing the mode and depth for each scar is central to the result. Check whether a doctor conducts both the consultation and procedure, whether authentic equipment is used, and whether regenerative care can be added for your scar type. At Dong-An Joongsim Clinic, a doctor personally assesses and treats your scars.
UltraPulse is Lumenis’ fractional CO₂ laser. We use UltraPulse Encore with SCAAR FX for scar treatment. Encore received US FDA 510(k) clearance in 2002; FDA documentation for the UltraPulse family includes acne and surgical scars among its indications.
CO₂ systems differ in pulse delivery, including continuous-wave, superpulse and ultrapulse modes. Continuous-wave delivery spreads heat over a broader, shallower area, with more surrounding thermal damage, downtime and discomfort. Short, powerful UltraPulse delivery creates narrow, deep channels with less surrounding thermal spread. According to our clinic’s treatment materials, one session may be comparable to three or more conventional fractional CO₂ sessions, with less discomfort and a lower risk of pigmentation. Outcomes depend on the device settings and the scar.
It is used for rolling, boxcar and ice-pick acne scars, as well as traumatic, surgical and burn scars. It can also address enlarged pores and wrinkles. In a study of 60 patients with traumatic or pathological scars, the UltraPulse Encore group showed greater improvement in tone and texture than the dermabrasion group.
We use topical anesthesia. Its short pulses can make treatment more comfortable than conventional fractional CO₂ resurfacing. If you are concerned about discomfort, we allow sufficient time for the numbing cream to take effect.
The laser creates very narrow channels, followed by fine crusting and redness during healing. In a study of 20 Korean patients after one UltraPulse Encore treatment for acne scars, crusting lasted about a week and redness averaged 2.8 days. Recovery varies with mode and depth, so we discuss timing during consultation.
Your doctor recommends a course based on scar depth and extent. A study of 44 acne-scar patients used at least two sessions; another involving 158 patients with hypertrophic face and neck scars used three sessions at three-month intervals. Extensive, thick burn scars may require more sessions.
Cost depends on scar location and extent, the mode used, number of sessions and any additional regenerative care. Your doctor assesses the scars and explains the cost during consultation.
