Subcision is a treatment that releases tethering beneath scars, and bruising and swelling may last 1–2 weeks. Released areas can re-adhere, so several sessions may be needed, and the realistic goal is to make scars less noticeable rather than to remove them.

01Overview

Subcision
Releasing the tethering that holds scars down from below

Subcision is a scar treatment in which a fine needle or blunt-tipped cannula is inserted beneath the skin to cut the fibrous bands that pull depressed scars downward.

How we approach it

The same device can be run very differently.

Depressed scars cannot be resolved with a single method. We first distinguish the scar types, then combine the methods needed, from Subcision to lasers.

Scar treatment does not repeat the same treatment every time. At each session, we look again at the shape of the remaining scars and decide on the next combination.

02What to expect

Changes over time

Once the tethering is released, the pressed-down base of the scar rises, and as the small space created beneath it heals, new connective tissue fills it in.

Right after treatment01

Right after treatment

The treated area begins to swell and bruise. Compression reduces bleeding and bruising.

A few days02

A few days

Bruising, swelling and tenderness to the touch may continue.

1–2 weeks03

1–2 weeks

Bruising and swelling mostly subside. The pace differs from person to person.

4–6 weeks04

4–6 weeks

We check how the released areas have healed and decide on the next treatment.

Over the sessions05

Over the sessions

Repeated if needed, and carried out in a set order alongside surface treatments such as lasers.

03Device & Technology

Subcision Device

Subcision

Needle · cannula

A fine needle or blunt-tipped cannula is used, matched to the depth and extent of the scar.

Releasing tethering

The fibrous bands pulling the scar downward are released beneath the skin.

Combined scar treatment

Surface irregularities are addressed with lasers and narrow, deep scars with TCA CROSS, working together.

04Procedure

How your visit goes

Specialist diagnosis01

Specialist diagnosis

We stretch the skin to check whether the scar is due to tethering, and mark the scars to be treated.

Anaesthesia02

Anaesthesia

Local anaesthesia is given at the marked areas.

Treatment03

Treatment

The specialist inserts a needle or cannula beneath the skin to release the fibrous bands holding the scar down.

Aftercare04

Aftercare

Pressure is applied to reduce bleeding and bruising, and we explain how to care for the area during recovery.

Every procedure is performed directly by a board-certified dermatologist.

05Aftercare

Recovery & care

  1. 01

    Day of treatment

    Apply pressure as instructed and do not rub the treated area. Avoid alcohol, saunas and strenuous exercise.

  2. 02

    First week

    Bruising and swelling may continue. If swelling is significant, use a cold compress.

  3. 03

    1–4 weeks

    If you feel a lump, or the area becomes red and increasingly painful, please contact us right away.

  4. 04

    Follow-up

    Based on how you have healed, we decide on the next session and the order of other scar treatments.

06FAQ

Frequently asked questions

What kind of treatment is Subcision?

It is a treatment in which a fine needle or cannula is inserted beneath the skin to release the fibrous tethering that pulls the scar downward. Once the tethering is released, the base of the scar rises, and as the area heals, connective tissue fills it in, bringing about change.

How can I tell if Subcision is right for my scars?

If a scar fades when you gently stretch the surrounding skin apart, it is likely a rolling scar with tethering beneath the skin. However, one face often has a mix of types, so we examine each scar individually to decide.

Does it hurt a lot?

It is performed after local anaesthesia, which reduces pain during treatment. Because it works beneath the skin, you may feel a pulling or dull, achy sensation, and after the anaesthesia wears off, the area may be tender to the touch for a few days.

Will there be a lot of bruising?

Because it works beneath the skin, bruising and swelling are common and may last around 1–2 weeks. If you have important plans, please let us know in advance during your consultation, and we will adjust the treatment timing together.

Is it combined with lasers?

Subcision releases the pulling force from below, while lasers refine surface irregularities and scar edges. That is why we often plan lasers such as Pico Fractional or CO2 Fractional, and TCA CROSS for narrow, deep scars, alongside it in a set order.

Can treated scars sink back down?

Released areas can re-adhere during healing, so treatment is sometimes repeated based on progress. At each session, we recheck the scar condition and decide on the next treatment.

Are there side effects, or cases where it is not suitable?

Bruising, swelling and tenderness are common, and lumps (nodules), infection or pigmentation may rarely occur. If you are taking anticoagulants or antiplatelet medication, are prone to keloids, are pregnant, or have an infection in the treatment area, please be sure to tell us during your consultation.

How much does Subcision cost, and how do I book?

The cost varies with the extent of scarring, the number of sessions and any treatments combined with it, so it is confirmed after examination. Non-covered treatment fees can be found on the pricing page of our website. Booking and consultations are available via Naver Booking, our KakaoTalk channel, or phone (+82-51-710-1891), and you can also consult with us via LINE.

Fees

Pricing depends on the extent of scarring, number of sessions and any combined treatments, and is confirmed after consultation.

Aftercare

Pore · scar lasers

These treatments create micro-injuries to trigger regeneration, so care over the following days is directly linked to the result.

Recovery course

  1. Day of treatmentRedness, warmth and swelling are clearly visible. Focus on soothing and moisturising.
  2. Days 2–4Fine crusts and flaking appear. Do not peel them off.
  3. Days 5–7Flaking settles and makeup can be worn comfortably.
  4. Months 1–3Changes in scars and pores appear over this period. If sessions are split, keep to the interval.

Precautions

  • Sun exposure: for at least 2 weeks; apply sunscreen daily
  • Sauna, hot baths, strenuous exercise and alcohol: for 3–5 days
  • Exfoliating products: for 2 weeks

When to contact the clinic

  • Weeping, pus or fever
  • Redness getting worse beyond 2 weeks
  • Blisters similar to cold sores if you have a history of herpes

Next session · next visitSessions are usually 3–4 weeks apart. Scars often need several methods combined.
