Many people struggle with deep acne scars that leave the skin looking uneven, shadowed or tethered. These scars often remain even after acne has long resolved, making makeup difficult and affecting confidence. When scars feel “stuck” to the deeper layers of the skin, topical products and resurfacing treatments often aren’t enough.
Subcision offers a targeted solution for these deeper, resistant scars. By releasing the tight fibrous bands beneath the skin, the procedure helps the surface lift and gradually regain a smoother, more natural contour. At Apax Medical, this technique is performed with precision to support proper healing and long-term improvement.

Subcision is a minor surgical procedure used to treat deep, tethered acne scars that pull the skin downward [1]. These scars are held in place by fibrous bands beneath the surface, which prevent the skin from smoothing out naturally. Subcision works by gently releasing these bands through a small entry point in the skin.
The procedure is performed in the clinic under local anaesthesia. Using a specialised instrument, the scar tissue anchoring the skin is carefully broken down. This release allows the skin to lift, while the healing process stimulates new collagen formation, helping the scar gradually improve in texture and appearance over time.
Subcision is best suited for scars that are tethered to deeper layers of the skin [2]. During consultation, we assess your scar type, depth and skin characteristics to determine if this method is appropriate. Scars that typically respond well to subcision include:
Rolling acne scars have sloping edges and can vary in depth. They should not be confused with ice-pick or boxcar scars, which have different shapes and require alternative treatment approaches.
Subcision works by releasing the fibrous bands that anchor acne scars to the deeper layers of the skin [3]. Using a fine needle or cannula, the scar tissue is carefully separated to create space beneath the surface. This release helps the skin lift and reduces the indentation caused by the tethering.
A small pocket of blood naturally forms under the treated area, preventing the scar from reattaching. This mild swelling (haematoma) gradually settles over a few weeks. As the area heals, the body begins producing new collagen, which further supports the lifted skin and improves overall texture.
Over time, this combination of mechanical release and natural collagen regeneration helps the scar soften and blend more smoothly with the surrounding skin.
Subcision is an effective option for treating deep, tethered acne scars that cause uneven skin texture. At Apax Medical, the procedure is performed with careful, controlled technique to ensure safe release of the fibrous bands that pull scars downward. Using a fine cannula or specialised needle, the scar tissue beneath the skin is gently separated to allow the surface to lift.
As the area heals, new collagen forms naturally within the treated region. This gradual regeneration helps fill the depressed scars and supports smoother, more even skin over time. With a personalised approach tailored to scar type and skin condition, subcision can significantly improve long-standing acne scarring while keeping downtime low.
Subcision can be performed using different instruments depending on the scar type and the area being treated. At Apax Medical, we select the method that offers the safest and most effective outcome for your skin.
Subcision is an in-clinic procedure carried out under local anaesthesia, making it comfortable and well-tolerated [5]. The skin is first cleansed and the scars are carefully mapped out before treatment. A small amount of anaesthetic is then injected to numb the area.
Depending on the scar type and depth, different instruments may be used. This includes fine hypodermic needles or specialised tools such as the Nokor needle, which is designed specifically for breaking the fibrous bands beneath the skin. During the procedure, the needle or cannula is guided under the scar to release the tissue that pulls the skin downward. You may feel a light “plucking” or snapping sensation as the bands are loosened.
In many cases, Dr Ng uses a blunt cannula technique to minimise trauma. This method helps reduce the likelihood of bruising, haematoma formation and pigmentation compared to traditional needle subcision.
Once the release is complete, gentle pressure is applied to reduce bleeding and swelling. A topical antibiotic ointment is placed over the treated area to support healing and lower the risk of infection.
Blunt cannula subcision offers several advantages over the traditional needle method. Because a flexible cannula with a rounded tip is used, the procedure causes less trauma to the surrounding tissue and requires fewer entry points through the skin. This generally leads to greater comfort during treatment and a more predictable healing process.
Both methods can achieve meaningful improvement in tethered scars, but the blunt cannula technique is associated with fewer side effects, such as bruising, swelling, haematoma formation and post-inflammatory hyperpigmentation. For these reasons, many patients prefer the cannula approach, especially when treating larger or more sensitive areas.
For deeper acne scars, Rejuran Scar treatment may be combined with subcision to enhance healing and improve overall skin texture [6]. Rejuran contains Polynucleotide (PN), a bioactive ingredient that supports tissue repair, collagen stimulation and scar remodelling.
Because Rejuran Scar has a thicker consistency than Rejuran Healer, it works well as a supportive treatment after subcision. Dr Ng may recommend injecting a small amount beneath the released scar to provide a scaffold for regeneration and to optimise long-term results.
Dermal fillers can complement subcision by lifting rolling or tethered scars and supporting smoother skin. At Apax Medical, we use hyaluronic acid–based fillers designed with cross-linking technology, giving them more stability and longer-lasting effect.
Hyaluronic acid naturally attracts water and helps maintain skin hydration, making it suitable for treating deeper atrophic scars. When combined with subcision, fillers such as Restylane or Profilho can further elevate the released scars, improve contour and deliver lasting cosmetic improvement.
Many patients have more than one type of acne scar and subcision is often paired with complementary treatments for a more complete improvement. For deeper, tethered scars, subcision may be performed together with TCA CROSS to treat ice-pick scars at the same session. Once the deeper scars have been successfully released, fractional resurfacing treatments such as Infini, Genius or Pico laser can further refine the skin and smooth remaining surface irregularities.
At Apax Medical, treatment plans are customised based on scar type, depth, and skin characteristics. Dr Moses Ng uses a combination approach where appropriate, ensuring each procedure supports the others for the best possible outcome.
Subcision remains a reliable method for treating deep, fibrous scars and a tailored, multi-step strategy often provides the most meaningful long-term improvement.

Subcision offers an effective way to improve deep, tethered acne scars that leave the skin uneven or depressed. By releasing the fibrous bands beneath the scar and stimulating new collagen, the procedure helps the skin gradually lift and regain a smoother contour. At Apax Medical, Dr Moses Ng tailors each treatment plan to your specific scar type and may combine subcision with complementary options such as laser resurfacing, TCA CROSS, Rejuran or dermal fillers for enhanced results.
If you are looking for a safe and proven method to improve the appearance of your acne scars, schedule a consultation with Apax Medical to explore the most suitable treatment approach for your skin.
Subcision is most effective for tethered scars, such as rolling scars and certain atrophic scars. Other scar types, like ice-pick or boxcar scars, often require different treatments.
Patients with active acne, bleeding disorders or very thin or sensitive skin around the area may not be ideal candidates. A consultation helps determine suitability.
Local anaesthesia is used, so most patients feel only pressure or a mild tugging sensation during the procedure. Discomfort afterwards is usually minimal.
Recovery typically takes a few days to a week. Bruising or mild swelling may occur but gradually settle as the skin heals.
The number of sessions depends on scar depth and severity. Many patients need 1–3 treatments spaced several weeks apart for optimal improvement.
Avoid strenuous activities, harsh skincare products and sun exposure for the first few days. Keep the treated area clean and apply the prescribed ointment as advised to support smooth healing.
Prices vary depending on the method used and whether it is combined with other treatments. The fee typically starts from $480 for cannula subcision.
Yes. Subcision is often paired with TCA CROSS, laser resurfacing, Rejuran or fillers for more comprehensive improvement, depending on the scar pattern.
