Subcision for Acne Scars

How it works

Rolling scars often look depressed because fibrous bands tether the skin to deeper tissue. In subcision, a fine needle or cannula is inserted under the scar through a small entry point and used to release those bands. The space may then fill with blood and new tissue, lifting the scar. Bruising and swelling are expected, and results vary by person and often need repeat sessions or other treatments.

Who it may suit

• Rolling or tethered acne scars
• Depressed scars that flatten when the skin is stretched
• People who have not improved enough with lasers alone
• Those who can accept a week or two of bruising

The treatment day

1. Scar assessment. The doctor stretches the skin and checks which scars are tethered, and asks about bleeding tendency, blood thinners and keloids.
2. Anesthesia. Local anesthesia is injected around the target scars.
3. Release. A needle or cannula is moved under each scar to free the fibrous bands, with pressure applied afterward.
4. Aftercare. Pressure or dressings, cold packs and written instructions are provided, and a review visit is set.

Aftercare

• Apply cold packs and pressure as instructed in the first day
• Expect bruising and swelling for one to two weeks
• Avoid blood-thinning supplements unless the doctor says otherwise
• Keep entry points clean and use sunscreen
• Report expanding swelling, severe pain, pus or fever

Things to know first

• Bruising, swelling, tenderness and small lumps are common
• Hematoma, infection and nerve irritation are uncommon but possible
• Overcorrection or new surface irregularity can occur
• Not usually suitable with bleeding disorders, anticoagulant use, active infection or keloid tendency
• Benefits vary by person and by scar type, and repeat sessions are often needed

What to check before booking subcision in Gangnam

Because no machine defines this procedure, ask about the operator. Who will perform the subcision, how often do they do it, and are they a physician? The depth and direction of the needle matter near blood vessels and nerves, and a poor technique can leave bruises, lumps or surface irregularity. A doctor who takes time to feel your scars and identify the tethered ones is demonstrating the assessment you want.

Ask which instrument is used and whether it is sterile and single-use. Needles or cannulas should come from sealed packaging. Also ask what the plan is after subcision: it is often combined with lasers, microneedling or fillers, and the order and timing matter. A clear plan explains why, and does not push multiple add-ons on the same day without reasoning.

A clear quote shows the area treated, anesthesia and follow-up, and states how many sessions are expected. Be cautious of promises that scars will be gone after one visit. A reliable consultation describes the bruising realistically, asks about blood thinners and supplements, and tells you that some scars, particularly deep icepick types, respond poorly to this method.
