What Is Subcision?
Subcision is a minor surgical procedure used in aesthetic medicine to improve acne scars, particularly depressed acne scars caused by tethered acne scars. It works by releasing fibrous bands beneath the skin surface that pull the skin downward, allowing the skin to lift naturally as it heals. Subcision for acne scars is especially effective for atrophic scars that do not respond well to topical or superficial treatments.
Subcision treatment overview
Sessions Required
Typically 1–3 sessions, depending on acne scar depth and severity.
Duration of Results
Results are long-lasting as new collagen forms, with gradual improvement over time.
Downtime
Minimal downtime; mild swelling or bruising usually resolves within 3–7 days.
Session Duration
Each subcision session takes about 30–45 minutes.
Skin Concern
Best suited for depressed, rolling, and tethered acne scars causing uneven skin texture.
What Is Subcision Treatment for Acne Scars?
Subcision acne scar treatment focuses on correcting deep acne scars and uneven skin texture by targeting scar tissue beneath the skin. During treatment, fibrous bands and fibrotic strands anchoring the underlying tissue are released, creating space for new collagen formation. As collagen rebuilds, the appearance of depressed scars improves, resulting in smoother and more even skin texture. This treatment is commonly recommended based on scar severity, scar depth, and individual skin condition.
How Does Subcision Work?
The subcision procedure involves inserting a specialised needle—such as a Nokor needle or cannula—into the deeper layers of the skin. This process releases tethered scars, breaks up fibrous tissues, and creates space for collagen production and collagen growth. As the skin heals, collagen forms, helping achieve lifted skin and improved skin texture over time.
What Types of Acne Scars Are Suitable for Subcision?
Subcision is suitable for several types of acne scars, particularly those involving tethering. However, it may not be recommended for keloid scars, hypertrophic scars, or patients with active skin infections.
Rolling Acne Scars
Rolling scars are among the most responsive scars to subcision. These atrophic acne scars are caused by fibrous bands pulling the skin downward, creating uneven texture. Rolling scars are characterized by sloping edges and can vary in depth, making them suitable for subcision treatment. Subcision acne scar treatment effectively releases the scar, allowing smoother skin as collagen rebuilds.
Ice Pick Scars
Ice pick scars are narrow and deep. Ice pick scars are more severe than boxcar scars and are characterized by their depth and thin imprints. While subcision alone may have limited impact on these deeper scars, it can be combined with other acne scar treatments to enhance results.
Boxcar Scars
Boxcar scars are wider depressions with defined edges. Boxcar scars resemble depressions or craters in the skin and are often broader than ice pick scars but not as wide as rolling scars. Subcision for acne scars can help improve these scars, particularly when fibrous bands beneath the skin are present. Combination therapy is often recommended depending on scar depth.
Benefits of Subcision for Acne Scars
Subcision treatment helps treat scars that are resistant to conventional acne scar treatments. It improves skin texture, supports collagen stimulation, and addresses the root cause of depressed scars. Subcision is particularly effective for deep, tethered scars that are difficult to treat with traditional methods. The treatment can be tailored based on skin type, scar types, and treatment goals. Subcision can also be used to treat scars resulting from trauma or surgery, as well as for certain types of wrinkles and cellulite dimples. Subcision is considered one of the safest acne scar removal procedures with minimal side effects.
Subcision Procedure: What to Expect
The subcision procedure is typically performed as an outpatient treatment and is well tolerated by most patients. The procedure is performed in the clinic under local anaesthesia, ensuring patient comfort during the treatment. Most patients describe the procedure as mildly uncomfortable rather than painful.
Pre-Treatment Consultation
A thorough consultation assesses scar severity, skin type, and suitable treatment options. Your doctor may recommend combine subcision with additional treatments such as laser resurfacing, dermal fillers, or Rejuran scar treatment for optimal results.
During the Subcision Treatment
The treatment area undergoes thorough cleansing before local anaesthetic is applied to reduce discomfort. The practitioner then performs the subcision treatment using a needle to release fibrous bands beneath the skin. The procedure is precise and controlled to minimise trauma.
Expected Recovery Timeline
After treatment, mild swelling and mild bruising are common due to minor excess blood in the treated area. These effects typically subside within a week. Recovery generally takes a few days to a week, allowing most patients to resume daily activities shortly after the procedure. Temporary numbness or a tingling sensation in the treated area is possible and usually resolves on its own within a few months.
Post-Treatment Care
Post-care may include applying a topical antibiotic ointment and avoiding pressure on the treatment site. Proper aftercare supports the healing process, protects the surrounding tissue, and enhances results as new collagen forms. It is important to follow the post-procedure care instructions given by a doctor to reduce the risk of complications and achieve the best results.
Subcision Combined With Other Acne Scar Treatments
Subcision is often combined with other acne scar treatments such as laser resurfacing, dermal fillers, of Korean PDRN S (Scar) Acne Scar Treatment. Hyaluronic acid fillers may be used to support volume while collagen rebuilds. Subcision can also be combined with other treatments such as fractional COâ‚‚ laser and fillers to enhance results. Combining treatments helps address different scar depths and improves long-term outcomes. Subcision is also frequently paired with RF microneedling to stimulate elastin and collagen fibers. Subcision is often paired with Rejuran S to stimulate collagen production and improve results.
Cost of Subcision in Singapore
The cost of subcision acne scar treatment depends on scar types, scar severity, and whether multiple treatment options are used. The cost of subcision treatments typically starts from $400. As a cosmetic scar treatment, it is generally not covered by insurance. Subcision is also considered a cosmetic treatment and cannot be paid for using Medisave. A consultation will determine the most appropriate approach.
3-Step Subcision Process at Fundamental Aesthetic Medical Clinic
Subcision at our clinic follows a structured approach:
-
Assessment and Planning – Evaluation of scars, skin condition, and suitable treatment options.
-
Surgical Subcision – Controlled release of scar tissue using advanced techniques.
-
Aftercare and Review – Monitoring healing as collagen rebuilds and skin texture improves.
Before and After Subcision
Before and after subcision results vary depending on scar depth and response to treatment. Improvements become more noticeable as collagen formation progresses and the released scar allows smoother skin. Visible results from subcision can often be seen after a few sessions. The number of subcision sessions required typically ranges from 2 to 4, spaced about 4 weeks apart.
Choosing the Right Subcision Doctor in Singapore

Look for expertise in subcision for acne scars, combination therapies, and personalised care tailored to your skin type and scar profile. Subcision is one of the safest acne scar removal procedures available, with minimal side effects and no risk of hyperpigmentation compared to lasers.
FAQ
Does subcision really work for acne scars?
Yes. Subcision is effective for releasing tethered acne scars, allowing the skin to lift and improve in texture.
How long do subcision results last?
Results are long-lasting, especially once collagen forms, though multiple sessions may be needed for optimal improvement.

Discomfort is minimal as local anaesthesia or numbing cream is used during the procedure.
How many subcision sessions do I need?
Most patients need 1–3 sessions, depending on scar depth and severity.
Which acne scars are best treated with subcision?
