Subcision is a minor surgical procedure that releases tethered acne scars by cutting fibrous bands under the skin with a needle, allowing the scar to lift. Results appear in 1–3 sessions, with bruising for 7–14 days. It works best for rolling and tethered boxcar scars.
What Is Subcision and How Does It Work
Subcision, short for subcutaneous incision, is done in-clinic under local anesthesia. A dermatologist inserts a special needle or Nokor needle under the scar to break the fibrotic strands pulling the skin down. Once released, the depression lifts. The controlled trauma also triggers new collagen, which gradually improves skin texture over 3–6 months. The procedure takes 20–40 minutes depending on scar count.
Types of Scars Subcision Can Treat
Subcision targets tethered scars with fibrous anchors. Ideal candidates:
Rolling scars: Wide, shallow depressions with sloping edges that look better when skin is stretched
Some boxcar scars: Only if the base feels tethered when you move the skin side to side
Cellulite dimples and wrinkles: Used off-label for certain depressed lines
It will not improve ice pick scars, raised keloids, active acne, or pigmentation alone. Those need TCA CROSS, laser resurfacing, or topical therapy.
Subcision vs Other Acne Scar Treatments
Patients often compare subcision to fillers, lasers, and microneedling. Here’s how they stack up:
| Treatment | Best For | Downtime | Permanent? | Mechanism |
| Subcision | Rolling scars, tethered scars | 7–14 days bruising | Results long-lasting | Cuts fibrous bands |
| Dermal Filler | Deep atrophic scars | 1–3 days swelling | 6–18 months | Adds volume under scar |
| Fractional Laser | Boxcar + texture | 5–10 days redness | Builds over sessions | Stimulates collagen |
| Microneedling RF | Mild scars, pores | 2–4 days | Needs 3–6 sessions | Micro-injury remodeling |
| TCA CROSS | Ice pick scars | 7 days pinpoint scabs | Permanent | Chemical reconstruction |
Dermatologists often combine subcision with filler or laser in one session. The release from subcision lets filler lift the scar higher, while laser improves surface texture.
What to Expect: Procedure Steps
Consultation: Your doctor maps tethered scars using stretch and side-lighting tests
Prep: Face is cleansed. Local anesthetic injected. You’ll feel pressure, not pain
Release: Needle is inserted and fanned under each scar to break bands. You may hear a snapping sound
Hemostasis: Pressure applied to limit bruising. Some doctors inject filler immediately after
Aftercare: Ice packs first 24h. Sleep elevated. Avoid blood thinners, alcohol, and intense exercise 48h
Subcision Recovery Time and Side Effects
Expect swelling and bruising for 7–14 days. Most bruises look like shadows under the skin and can be covered with makeup after 48h. Small lumps or “nodules” are common for 1–2 months as collagen forms; they settle on their own.
Rare risks: infection, nerve injury, prolonged swelling, or new hypertrophic scarring. Choosing a board-certified dermatologist trained in acne scar revision reduces risk.
How Many Sessions Do You Need
Mild rolling scars: 1–2 sessions spaced 2–3 months apart
Moderate to severe: 2–4 sessions, often combined with energy devices
Results are gradual. Photos at 3 months post-treatment show the real change as collagen rebuilds. Subcision creates a permanent release, but new collagen depends on your healing. Maintenance is rarely needed unless new scars form.
Subcision Cost in 2026
Pricing varies by location, provider experience, and whether filler is added.
| Region | Per Session Cost | Notes |
| Malaysia | RM800–RM2,500 | KL/PJ clinics vary |
Packages of 3 sessions + laser can run higher. Always confirm if consultation, numbing, filler, and follow-ups are included.
How to Prepare for Subcision
Stop aspirin, fish oil, vitamin E, and NSAIDs 7 days before to reduce bruising. Avoid alcohol 48h prior. Tell your doctor about bleeding disorders or keloid history. Arrive with a clean face. Plan no events for 2 weeks if you bruise easily.
Aftercare for Best Results
Day 0–2: Ice 10 min/hr while awake. No gym, hot yoga, or saunas
Day 3–7: Gentle cleanser, moisturizer, SPF 50+. Mineral makeup okay
Week 2+: Begin scar massage if advised. Start retinoid only after skin heals
Month 1–3: Collagen remodeling phase. Sunscreen prevents post-inflammatory darkening
Is Subcision Permanent
The fibrous bands do not regrow once cut, so the mechanical release is permanent. However, aging, volume loss, and new acne can change how scars look years later. Most patients report 40–70% improvement in rolling scars after a full course.
Who Should Avoid Subcision
Not suitable if you have active cystic acne, blood clotting disorders, uncontrolled diabetes, or a history of hypertrophic scars. Pregnant patients should wait. Darker skin types need careful technique to avoid post-inflammatory hyperpigmentation.
Choosing a Subcision Provider
Look for a dermatologist or plastic surgeon who performs scar revision weekly, not occasionally. Ask to see before/after photos of rolling scars, not just general “acne scar” cases. Confirm what needle type they use and if they combine with suction, filler, or laser. Reviews mentioning “minimal bruising” and “natural results” matter more than price alone.
FAQs
1. How painful is subcision?
With local anesthetic, you feel pressure and tugging but not sharp pain. Most rate it 2/10. Soreness for 1–2 days after is normal.
2. Can subcision make scars worse?
If done too aggressively or on the wrong scar type, it can cause lumps or new scars. Proper patient selection and technique keep risk under 2%.
3. How long does bruising from subcision last?
Average 7–10 days. People who bruise easily may see discoloration up to 3 weeks. Arnica and bromelain can help.
4. Is subcision better than laser for acne scars?
They solve different problems. Subcision releases tethered scars. Laser improves surface texture. Best results come from combining both.
5. When will I see results after subcision?
Initial lift is seen once swelling settles at 2 weeks. Collagen remodeling continues, so final result is at 3–6 months.
