Keloid Scar Removal

Overview

PurposeTreating raised scars caused by excessive collagen production, aiming to reduce scar thickness, relieve symptoms such as itch or discomfort and lower the risk of recurrence.
Recommended forIndividuals with keloid or hypertrophic scars that are raised, enlarging, symptomatic or causing cosmetic concerns.
Surgery timeInjections and laser treatments are typically short outpatient procedures, while surgical excision may take approximately 1–2 hours depending on scar size and location.
Hospital stayMost treatments are performed as outpatient procedures. Surgical excision is usually day surgery unless otherwise advised.
RecoveryReturn to light daily activities is usually possible shortly after non-surgical treatment. After surgery, stitches are typically removed within 7–14 days, with ongoing scar maintenance and follow-up over several months.

Keloid scars can be uncomfortable, persistent and emotionally distressing. Many patients struggle with scars that continue to grow beyond the original wound, causing itchiness, tightness or pain, and often affecting confidence in visible areas.

Asians are at higher risk and more prone to developing keloids compared to Caucasians. In Singapore, with our diverse ethnic population, scar treatment in Singapore is a very common and important concern. This increased risk is partly related to skin biology and pigmentation, but skin colour alone does not tell the whole story.

Keloid scars are raised, thickened scars that grow beyond the boundaries of the original wound.

What is a keloid scar?

A keloid scar is a type of abnormal scar that forms when the body produces excessive scar tissue during healing. The scar grows beyond the original wound and does not flatten or fade over time. In some cases, it may continue to grow in size.

Symptoms may include:

  • Itchiness
  • Pain
  • Tightness
  • Sensitivity
  • Recurrent inflammation or infection. In certain cases, infection may require antibiotics or surgical debridement. 

Asians are more prone to developing keloids due to higher melanin concentration and denser collagen structure in the skin. In multi-ethnic Asian populations such as Singapore, keloids and hypertrophic scars are therefore commonly seen in our clinical practice.

Why do some people develop keloids?

Keloids are an exaggerated healing response where scar tissue continues to grow beyond the original wound. Although benign, they may behave in a tumour-like manner and grow much larger than the initial injury.

Asians are more predisposed to developing keloids. Other risk factors include:

  • Mode of injury such as trauma, burns or surgery
  • How the initial wound was treated
  • Presence of infection
  • Wound tension during healing
  • Post-healing scar care

For example, a well-stitched laceration with minimal tension, proper wound care and early silicone scar therapy is far less likely to develop into a hypertrophic scar or keloid compared to wounds that heal under tension or are poorly managed.

Keloid Vs

Hypertrophic Scars

Although both keloids and hypertrophic scars are both raised scars, they differ in behaviour, growth pattern and risk of recurrence.

Who is keloid scar removal recommended for?

Keloid scar removal may be considered for individuals who:

  • Have large, bulky or thickened keloids
  • Experience persistent itchiness, pain or tightness
  • Have recurrent inflammation or infection
  • Notice continued growth despite non-surgical treatment
  • Have scars that restrict movement due to location
  • Feel significant cosmetic concern, particularly in visible areas

What to expect for your first consultation

Every scar has a story. No two scars, or patients, are the same. That is why Dr Pearlie begins every scar consultation by understanding your medical history, the history of your scar, and your personal goals and expectations before recommending the most suitable treatment plan.

How is a keloid scar removed and treated?

Effective keloid scar treatment often involves a combination of therapies.

Intralesional steroid injections remain a cornerstone treatment for hypertrophic scars and keloids. They work by reducing inflammation and suppressing excessive collagen production, which helps to flatten raised scars and relieve symptoms such as itchiness and tightness.

Treatment response depends on factors such as dosage, concentration and injection. Careful administration is important to balance effectiveness while minimising unwanted skin thinning or pigment changes.

Steroid injections may be combined with botulinum toxin injections to reduce fibroblast activity and mechanical tension within the scar. Proper technique and dosing are essential.

Laser therapy plays an important role in keloid and hypertrophic scar management, but the type of laser used must be carefully selected based on the stage of the scar.

  • Vascular lasers are used early to reduce redness, inflammation and excessive blood supply that can drive continued scar growth. Controlling inflammation at this stage helps reduce further collagen stimulation.

  • Fractional CO₂ laser is introduced once inflammation subsides to remodel collagen and improve texture and soften thickened scar tissue. 

Using inappropriate lasers, or treating a scar at the wrong stage, will worsen scarring or cause pigment changes, particularly in Asian skin.

Surgery may be recommended for large, bulky, infected or symptomatic keloids, or when non-surgical treatment is insufficient. However, Dr Pearlie also cautions that surgery alone is not adequate. Without early post-surgery laser therapy and silicone scar sheet maintenance, recurrence is highly likely and may result in larger re-growth.

Post-operative management may include:

  • Early vascular laser therapy
  • Silicone scar sheet maintenance
  • Compression therapy such as ear clips for ear keloids

Silicone sheet therapy works by reducing transepidermal water loss (TEWL), improving scar hydration and helping to regulate collagen production during the healing process.

Long-term scar control is an important part of keloid and hypertrophic scar management, as these scars have a tendency to recur if not carefully monitored. Treatments may include:

  • Silicone scar sheets or gel, which help regulate hydration and support controlled healing
  • Compression therapy, such as compression garments or ear clips, to reduce mechanical tension on the scar
  • Structured follow-up and staged laser therapy to monitor scar behaviour and intervene if signs of thickening or inflammation recur. The appropriate type of laser must be selected, as the use of an unsuitable laser will worsen the keloid.

Why a scar surgeon matters

Most scars arise from trauma or surgery. Consultation with a surgeon experienced in scar management is most ideal for scar treatment in Singapore.

According to Dr Pearlie, surgical expertise matters not only in treating existing scars but also in preventing recurrence. In selected cases:

  • Minor scar revision surgery may significantly improve appearance
  • More severe scars may require surgical excision with skin flap reconstruction

Careful planning, skin tension control and structured follow-up are key components of successful keloid management.

Recovery and preventing recurrence

Recovery after surgical keloid removal depends on the size and location of the scar, but most patients are able to return to light daily activities relatively quickly. Specialised dressings, such as vacuum-assisted dressings, and stitches are usually removed within 7–14 days, depending on wound healing.

Once stitches are removed, vascular laser therapy is typically started very early, typically within 7-14 days after any surgical revision, to reduce inflammation, redness and the risk of recurrence. Early laser intervention plays an important role in a structured keloid management plan. It is equally important to emphasise that the appropriate type of laser must be selected, as the use of an unsuitable laser will worsen the keloid.

During recovery, Dr Pearlie provides step-by-step guidance on silicone scar sheet or gel application and the appropriate use of compression therapy. This may include compression garments, ear clips for ear keloids or supportive clothing depending on scar location.

By reducing trans-epidermal water loss (TEWL), silicone sheets help regulate collagen activity and improve scar hydration, which supports more normal healing.

Because keloids have a well-known tendency to recur, treatment does not end with surgery alone. Successful long-term control relies on a combination of carefully planned surgical techniques, tension-reducing dressings and early post-operative laser therapy to regulate collagen production and scar behaviour. It is equally important to emphasise that the appropriate type of laser must be selected, as the use of an unsuitable laser will worsen the keloid.

Most patients notice gradual improvement in comfort and appearance early within the next few weeks and months that follow. Consistent follow-up and adherence to the after-care plan are key to maintaining flatter, softer and more stable scars over time.

How much does keloid

removal cost in Singapore?

Keloid treatment in Singapore by a scar specialist depends on the type and severity of the scar, and whether treatment involves laser therapy and injections alone or combined with surgical removal. 

Generally, treatment costs usually range from $1,000 to $6,000, depending on the complexity of the scar and the treatment plan required. Dr Pearlie will discuss the recommended treatment plan and expected costs upfront, so you can make an informed and comfortable decision.

How scar treatment is personalised to you

Keloid scars are particularly challenging because of their complex and exaggerated healing behaviour. Unlike ordinary scars, they do not simply mature and settle over time. Instead, they may continue to grow, recur after treatment and respond unpredictably if not carefully managed.

This complexity means that keloid treatment cannot follow a one-size-fits-all approach. Careful assessment of the scar’s history, location, prior infections and current activity is essential before deciding on the most appropriate strategy. Timing of intervention, selection of laser type and the use of adjunct therapies such as steroid injections, botulinum toxin, silicone therapy and compression all need to be staged thoughtfully.

Frequently Asked

Questions

How do I know if my scar is a keloid or a raised scar?

If your scar grows beyond the original wound or continues enlarging over time, it is more likely a keloid. If it remains within the wound boundaries and stabilises, it is more likely hypertrophic.

If unsure, a clinical examination can confirm the diagnosis.

Yes. Smaller or early keloids may respond to laser therapy, steroid injections, botulinum toxin and silicone therapy. Surgery may be recommended if the keloid is large, infected, restricting movement or unresponsive to non-surgical treatment. Surgery is always combined with post-operative laser therapy and silicone scar maintenance. It is equally important to emphasise that the appropriate type of laser must be selected, as the use of an unsuitable laser will worsen the keloid.

Stitches and specialised dressings are usually removed within 7–14 days. Early vascular laser therapy is typically started soon after stitch removal.

Silicone therapy and compression may continue for several months. Regular follow-up plays an important role in reducing recurrence.

Treatment is individualised. Some patients are followed closely for around six months during active phases. Others may choose longer-term follow-up over 3–4 years.

At the beginning of treatment, follow-up visits are usually closer together to closely monitor the scar’s response and adjust treatment as needed. As the scar stabilises and improves, visits are typically spaced further apart. Many patients then transition to annual reviews, allowing them to keep in touch and consider repeat laser or maintenance scar therapy if requested.

In short, keloid scar treatment in Singapore is best viewed as a long-term management plan, rather than a one-off procedure. Ongoing monitoring helps ensure the scar remains flat, comfortable and well-controlled over time.

Most patients tolerate keloid scar treatment very well. Before any laser or injections, a strong numbing cream is applied for about 30-40 minutes to reduce discomfort.

If surgery is required, local anaesthesia is given to fully numb the area before the procedure begins.

During treatment, some patients may feel pressure or mild discomfort, but this is usually well tolerated and settles quickly once the procedure is completed. Pain after the procedure is typically minimal and manageable, and most patients are able to resume normal activities shortly after.

Overall, keloid scar treatments are designed to be as comfortable and safe as possible, with pain control tailored to each patient’s needs.
