Scar Regeneration Acupuncture (Saesalchim) [to fill depressed scars]
By directly removing the fibrous tissues that pull down depressed scars, one by one, this treatment helps new skin to regenerate and fill the indentation.

KKEUT Clinic “Saesalchim” — Subcision Scar Treatment
What Sets Us Apart
Our 3-Step, Layer-Specific Approach
Step 1 — Release of superficial tethering
We use fine micro-needles to precisely cut the broad, shallow fibrous adhesions just under the skin. This frees the surface so the visible depressions look smoother and more natural.
Step 2 — Deep adhesion release (with cannula)
Stronger, “root-like” adhesions anchored in the deep dermis/subcutis are released with a cannula across a wider area—gentler and safer than the older Nokor technique (which often caused more bruising and pain). This step is critical for rolling and boxcar scars and helps minimize bruising and discomfort.
Step 3 — Regeneration signaling (micro-needling)
Finally, controlled micro-bleeding is induced with micro-needles to summon blood flow and growth factors, activating fibroblasts so collagen remodeling can truly begin.
Thoughtful Combination Therapy (Our “Must,” not an option)
① PDRN (polynucleotide) injections — included by default
We pair every subcision with PDRN to support faster wound healing, help reduce redness/PIH, and enhance scar remodeling. For us, it’s standard, not an add-on.
② Fast-recovery Er:YAG fractional laser — routinely combined
Subcision changes the internal structure, but the surface may still need refinement. We therefore add Er:YAG fractional resurfacing after subcision to improve texture, pores, and micro-depressions—with short downtime and amplified results.
Why KKEUT for Subcision?
- Anatomy-guided planning
- We don’t “just go deep.” We map which layer is tethered and which direction to release—from diagnosis to plan.
- Precision tools
- A tailored mix of needles, cannulas, and micro-needles helps reduce bruising, swelling, and pain while preserving efficacy.
- PDRN + Fractional = our default protocol
- Regeneration and efficiency boosters are built in to raise outcomes and speed recovery.
- Honest indications
- Subcision is not right for every scar. When a scar doesn’t need it, we’ll simply say “You don’t need this.” Judgment comes before suggestion.
What Is Subcision?
Depressed scars are often tethered from below by fibrous bands that pull the skin inward.
Subcision cuts those fibrous tethers so the skin can rise back up.
How It Works
- Release (cutting adhesions) — With a needle or cannula, we sever the fibrous bands so the depressed area lifts naturally.
- Regeneration signal — The micro-bleeding from release is an intentional signal that triggers collagen synthesis.
- Blood flow + remodeling boost — Micro-needling plus PDRN concentrate repair cells and growth factors, promoting healing and collagen at the same time.
Who Is a Good Candidate?
- Ice-pick-like pits on the forehead
- Hollowed/uneven temple scars
- Pin-point depressions on the nose
- Mixed cheek scars (rolling/boxcar/ice-pick combinations)
“Multi-Subcision” (3-Step Subcision + Er:YAG Shoulder-ing)
An upgraded protocol that adds shoulder-ing (edge feathering) to classic subcision.
Even when the bottom is released, steep scar edges can limit how smoothly the center fills. The skin tends to heal toward the height and texture of its surroundings, but sharp walls block that blending.
Shoulder-ing lightly feathers the scar rim with Er:YAG, creating a gentle slope so the rising center can merge seamlessly with nearby skin—often the missing piece when previous subcision didn’t meet expectations.
Who Benefits from Multi-Subcision?
- Limited improvement from prior subcision/laser
- Often the issue is not the release below, but the steep edge above. Shoulder-ing addresses that.
- Deep, sharply edged scars (e.g., boxcar)
- Softening the vertical wall helps the central area fill and blend more naturally.
- Fewer sessions, clearer change
- Because we treat the bottom (tethers) + sides (edges) + top (texture) together, many patients feel improvement in fewer visits than with subcision alone.
Notes & Expectations
- Bruising, swelling, and tenderness are common for a few days; we minimize these with cannula technique and built-in PDRN.
- PIH risk is managed with parameter control, cooling, sun protection, and post-care guidance.
- Some scars require staged sessions; we’ll map your scar types (rolling/boxcar/ice-pick) and sequence the plan accordingly.
- Individual results vary with scar depth, skin biology, and aftercare. We’ll guide you through a practical, stepwise plan for steady improvement.
Q&A
고객님들이 가장 많이 물어보시는 내용을 모았습니다.
Is Saesalchim painful?
It feels similar to extractions, and we assist with the procedure after applying numbing cream.
How many sessions are usually recommended?
We recommend a minimum of 10 sessions. However, the number of sessions may vary depending on the depth, shape, and skin condition of your scar, and a more suitable procedure may be recommended based on your condition.
Is there any downtime?
It may be accompanied by redness, but it does not interfere with daily life. However, there are individual differences in how long it takes for the red marks to completely disappear.
What is the difference between Saesalchim and Multi-Saesalchim?
Saesalchim is a procedure that severs the fibrous tissue beneath the scar, allowing the scar base to regenerate and rise. Multi-Saesalchim is an enhanced procedure that, in addition to the effects of traditional Saesalchim, includes a process of gently refining the periphery of depressed scars. It is effective for deep scars with distinct edges and is a more comprehensive scar treatment method.
If the skin is shaved with Multi-Saesalchim shouldering, will the scar not appear larger?
Even if the edges are shaved with shouldering, the scar does not appear larger. Shouldering does not widen the scar; instead, it is a process that gently reshapes distinct edges to encourage our body to regenerate the skin to be similar to the surrounding area, thus allowing it to fill in more naturally.
