Depth - target layer
Small deep pits and broad shallow depressions need different target depths.
Scar recovery is not guesswork.
It starts with reading the structure.
Pitted scars differ in depth, edge, tethering, and response. RECOVER reads those factors separately and plans the depth, direction, and spacing of Saesalchim — a needle approach entered from beside the scar — for each scar.

When scars are separated,
what to review first becomes clearer.
When pitted scars, red marks, and pigmentation appear together, one procedure name cannot explain the plan. RECOVER organizes what to calm, what to review now, and what to review later.

Range and priority
Across Saesalchim, laser, and skin booster, the plan separates what to address first and what to set aside for later.
Each scar needs
a different layer, direction, and interval
Once scars are separated, the next question is where to enter. Saesalchim is not a one-depth needle - RECOVER plans which layer, direction, and interval to enter by each scar's depth, edge, tethering, response, and spacing.
Edge - where direction changes
Sharp-edged scars are read by the border first; deep-based scars by the lower layer.
Tethering - pull beneath the surface
Broadly tethered scars and shallow spread differ in the range of subsurface pull.
Skin response - calm first or proceed
If redness, pigment, or sensitivity remains, intensity and order are adjusted to skin response.
Interval - one step or staged
The next interval and comparison standard are set around the pace of skin recovery.
Saesalchim procedure video
We do not keep treating only the surface.
We check the tethering beneath pitted scars.
Saesalchim does not cover the scar from above; it enters from the side and releases the tethering beneath. As new tissue fills the released area, depth, direction, and interval are adjusted by scar type and skin response.

LEGACY CLINICAL RECORDS
Start with two records of different pitted scars
Two representative pitted-scar records. Only the patient-photo areas were cropped, and skin, color, lighting, and shape were left untouched. The remaining three clinical records and the capture conditions are gathered on the clinical evidence page.
CASE 01Woman · mixed pitted scars
CASE 03Man · severe acne scars and pores
Comparison note These records predate the scar-dedicated capture rig that RECOVER built in-house and installed in the Gangnam clinic. Timing, lighting, angle, and expression differ by case and can affect appearance; individual outcomes vary with scar structure and skin response. Saesalchim and needle procedures can cause side effects such as pain, redness, bruising, swelling, bleeding, pigmentation, or infection.
NAVER VERIFIED VISITS
Review three representative accounts of assessment, precision, and recommendations
All ten reviews are visit-verified through Naver booking or receipt records, and six were left by returning patients. One each was selected for scar assessment, procedure precision, and pressure-free consultation.
“The doctor looked at each scar shape … and explained it clearly.”
“I could feel how meticulous and precise the doctor was with each part of the procedure.”
“There was no pressure toward an expensive package or unnecessary procedure, which made me feel at ease.”
Reviews describe individual experiences, and outcomes vary. Sources and further information are available on the clinical evidence page.
Differences that surface photos miss
are reviewed on the same 3D baseline.
RECOVER AI organizes scar mapping, tethering prediction, and facial balance for clinician review. All marks are AI candidates; the final decision is made by the clinician.
The relief a single photograph misses,
raised by light from seven directions
This is not a synthetic screen. It is a real record from the scar measurement device RECOVER built part by part. The skin inside a 29.4 × 21.2 mm window is lit from seven directions, and the shadows are combined to raise the surface relief in 3D. Measuring the same site again under the same conditions is the device's job; what is a scar and where to approach it is the clinician's reading.
01 / Actual captureAverage of 7 light directions

The original frame from the camera inside the device. One pixel is 0.03 mm, so a single pore spans dozens of pixels.
02 / Surface relit from seven directions7 directions → relief

The shadows from seven light directions are combined so that only the surface relief remains. Texture hidden under colour and redness comes through as it is.
03 / Relief raised in 3DRelative height · height ×8.5
Drag to rotate · wheel to zoom
The same relief is raised as height on a grid. Where and how much the surface dips is visible at a glance, and the next visit is compared on the same grid.

A device that proves its own precision — a comparison baseline that tightens with every re-seat
Number of times the probe was re-seated on the same site
The device sets the comparison baseline
Even lifted and re-seated,
0.05 mm or closer
Lift the probe and seat it again, and the value moves. So RECOVER uses the average of eight re-seats on the same site as the comparison baseline. That baseline settles within 0.05 mm, and the change at the next visit is read on top of it. This is possible because the device measures its own precision.

Before touch confirmation,
Hidden tethering ranges are predicted first
A pit can look deeper because tissue beneath pulls it down. PULL MAP suggests the range and direction of possible tethering, and the clinician confirms it directly before setting the entry area.
Not only scars,
facial balance is reviewed by the same standard
Asymmetry cannot be judged from one impression. Reference points around the eyes, cheekbones, mouth, and jawline are kept in 3D for comparison by the same standard next visit.
View facial balance references →The instrument that measures a scar under one condition —
we built it from the parts up
To keep one scar site under the same light and angle, we designed the lighting, controller and review screen ourselves. Surface shape is recorded in 0.01 mm units and followed with the same device, site and capture conditions. HAN PREDICT, the company that builds RECOVER AI, was founded by Han Cheong Woo.

After the first consultation,
a baseline note remains
RECOVER NOTE is the scar recovery baseline organized during consultation. It summarizes where scars are pitted, why they look tethered, and what to review now versus later, on one page.
01
Where scars and marks remain
A scar map records indentation, redness, pigmentation, and texture under the same standard.
02
Scar type and depth
Your scar pattern and the layer of depression are separated by type.
03
Tethering direction and range
The note records not only surface indentation but also suspected direction and range of pull beneath it.
04
Now and later zones
Rather than reviewing everything at once, priority is staged from what matters first.
05
Redness, pigment, and sensitivity check
Recent procedure history is checked together before deciding when to start.
06
Next comparison standard
Items for the next review are set in advance under similar lighting, angle, and distance.
Before choosing a procedure name, RECOVER leaves a standard for reading your scars.
Recovery is about identifying the conditions that slowed improvement and setting a standard to compare again.

WHY RECOVER
Han Cheong Woo focused on a recurring problem in scar care: after repeated procedures, many patients still cannot tell what improved and what remains.
RECOVER began from a record-based method: AI-assisted SCAR PREDICT marking, clinician interpretation, and Saesalchim approach criteria, rather than vague impressions.
That is why the first consultation organizes where to approach, how to approach, and what to compare later in RECOVER NOTE before discussing treatment counts.

FREQUENTLY ASKED
Frequently asked questions
The consultation begins by reviewing scar location, depth, edge, tethering, redness, pigmentation, and previous treatment history. RECOVER NOTE then records what to approach now and what to review over time.
Pitted scars, red marks, pigmentation, and sensitivity are reviewed by distinct criteria and in a deliberate order: what should calm first, what can be approached now, and what should be decided through follow-up.
Scars can look different depending on light, angle, and expression. RECOVER leaves a baseline from the first consultation so later skin response and next steps can be compared under similar conditions.
Yes. We review remaining indentation, redness, pigmentation, sensitivity, and texture after previous treatments. The important point is what remains in the skin now.
It depends on scar depth, width, tethering, and skin response. The first consultation sets the first approach range and a 6-12 week comparison standard, then adjusts the next step by response.
Because the process checks tethering beneath pitted scars, stimulation can be felt. RECOVER adjusts range and interval by scar depth and skin response and explains expected stimulation and recovery flow during consultation.
Redness and pigmentation follow a different standard from pitted scars. We first review skin condition and sensitivity for color changes, then assess depth and tethering for pitted scars and set the order of calming, surface care, and Saesalchim when needed.
Every non-covered fee is published item by item on the fee schedule. One Saesalchim session is KRW 110,000 for a point, 330,000 for a local area, 550,000 for the standard both-cheek range, and 770,000 for the wide range; multi-visit scar programmes are priced by their composition. Which items run in which order is decided after scar type, approach range, and priority are reviewed at the first consultation.
The opening date for RECOVER Clinic Gangnam is September 7, 2026. The first consultation organizes scar type, Saesalchim range, and a 6-12 week comparison baseline in RECOVER NOTE.
RECOVER offers CO2 and Nd:YAG lasers, radiofrequency, and skin boosters alongside Saesalchim. Laser and radiofrequency mainly address surface color, texture, and redness, while Saesalchim addresses the tethering and depth beneath pitted scars. What to use first is decided by reading the scar structure, not by the device, and that order and range are recorded together in the RECOVER NOTE.
Both approaches consider tethering beneath pitted scars. RECOVER Saesalchim is based on side entry and detailed adjustment of depth, direction, and interval according to scar type and skin response.
