Burn Scar Removal
Overview
| Purpose | Managing burn scars by improving scar thickness, texture, pliability and overall appearance, while helping relieve symptoms such as itch, tightness or discomfort and reducing the risk of scar contracture. |
| Recommended for | Individuals with burn scars that are raised, thickened, discoloured, tight or affecting movement, as well as those experiencing symptoms such as itch, pain or sensitivity. |
| Surgery time | Laser treatments and injections are typically short outpatient procedures. Surgical scar revision or contracture release may take approximately 1–4 hours, depending on the size, location and complexity of the scar. |
| Hospital stay | Most treatments are performed as outpatient procedures. Surgical scar revision is usually carried out as day surgery, unless otherwise advised. |
| Recovery | Light daily activities can usually be resumed shortly after non-surgical treatments. After surgical scar revision, stitches are typically removed within 7–14 days, with ongoing scar care and follow-up over several months as the scar continues to mature. |
Burn scars can form after injuries caused by heat, hot liquids, flames, chemicals or electricity. Beyond the physical pain of the burn itself, many patients find that the resulting scars can also carry difficult memories of the incident. For some, the scar serves as a constant reminder of a traumatic event, particularly when the injury involved an accident or a fire.
In Singapore, burns commonly occur from domestic scalds such as hot water, soups or steam, while more severe cases may arise from industrial accidents, electrical injuries, chemical exposure or road traffic accidents. These injuries can lead to visible scarring that may feel tight, itchy or uncomfortable and, in some cases, restrict movement if located near joints.
Specialist burn scar treatment in Singapore may involve surgical scar revision, appropriate laser treatments and targeted injections depending on the scar’s characteristics. Early assessment by a plastic surgeon can help guide appropriate treatment and support better long-term outcomes.
What are burn scars?
A burn scar forms when the skin heals after damage caused by heat, hot liquids, flames, electricity or chemicals. When the injury penetrates deeper layers of skin or takes longer than two to three weeks to heal, the body may produce excess abnormal collagen during the healing process.
This excessive abnormal collagen production can lead to thickened, raised and discoloured scars. Burn scars may develop into:
- Hypertrophic scars — which remain within the boundaries of the original injury but become raised and firm.
- Keloids — which grow beyond the edges of the original wound.
- Scar contractures — where the scar tightens and restricts surrounding tissue movement.
Burn scars may appear red, itchy, firm or tight. In some cases, they can limit mobility when located across joints such as the neck, shoulders, elbows or knees.
What determines how a burn scar develops?
The final appearance of a burn scar is influenced by several factors during the early stages of healing, including:
- How quickly the burn receives medical treatment
Prompt treatment can reduce tissue damage and lower the risk of severe scarring. - How long the wound takes to heal
Burn wounds that heal within about 2–3 weeks are less likely to form hypertrophic scars or keloids. Wounds that take longer to heal have a higher risk of abnormal scarring. - Whether infection occurs during healing
Infections can prolong inflammation and disrupt normal healing, increasing the likelihood of thicker or more irregular scars. - The type of wound care and dressings used
Appropriate wound management helps support faster healing and reduces excessive scar formation. - When scar treatment is started
Early scar management, such as silicone therapy, compression therapy and appropriate laser treatment, will help control inflammation and regulate collagen production.
Because these factors occur early in the healing process, timely assessment and management can significantly influence the long-term appearance and behaviour of a burn scar.
How are burn scars
diagnosed?
Generally, burn scars are diagnosed through a clinical examination by a plastic surgeon who is experienced in the management of acute burns and the after-care from healing to burn scar management. The following factors may be evaluated:
- Type of scar – whether the scar is hypertrophic, keloid or a contracture
- Scar thickness and firmness – raised or thick scars may indicate excessive collagen formation
- Scar maturity – whether the scar is still inflamed and immature or has matured over time
- Symptoms – such as itch, pain, tightness or sensitivity
- Functional impact – whether the scar restricts movement, particularly near joints
Your scar specialist will also review the history of the burn injury, including how the burn occurred, how long the wound took to heal and whether infections developed during the healing process. These factors can influence the type of scar that forms.
In most cases, imaging tests or biopsies are not required, as burn scars can typically be diagnosed through careful clinical assessment. The findings from this evaluation will guide an appropriate treatment plan for burn scar management.
How are burn scars treated in Singapore?
Early burn scar treatment may include silicone therapy, compression therapy and laser treatments. In many cases, Dr Pearlie combines laser therapy with intralesional steroid injections, with or without botulinum toxin injections, delivered into and around the scar to regulate scar activity. This combined approach helps reduce inflammation, regulate collagen production and improve the long-term appearance and pliability of the scar.
Laser Scar Therapy
Laser scar treatment plays an essential role in specialist burn scar management. However, not all lasers are suitable for scars. The type of laser and timing of treatment must be carefully selected based on the scar’s stage of development.
Using inappropriate lasers at the wrong stage will worsen inflammation, pigmentation and negatively affect scar outcome.
Vascular Lasers (Early, Red Scars)
In immature, red, inflamed scars, a vascular laser is introduced early to:
- Reduce redness
- Decrease inflammation
- Suppress abnormal blood vessel activity
- Lower the stimulus for hypertrophic scarring and keloid formation
Controlling inflammation early is critical in preventing excessive abnormal collagen deposition and dampens symptoms such as itching and pain.
Fractional CO₂ Laser for Mature Scars
Once the scar has matured and redness has subsided, a fractional CO₂ laser may be used to:
- Improve scar texture
- Remodel abnormal collagen
- Soften thickened tissue
- Improve skin pliability
- Enhance overall cosmetic appearance
Clinical studies have shown CO2 fractional laser resurfacing helps the scar behave and appear more like normal surrounding skin.
Scar Injections for Raised or Symptomatic Scars
Raised, itchy or firm scars may be treated with targeted injections delivered directly into the scar.
Intralesional corticosteroid injections help reduce excessive collagen production and flatten thickened scars.
Botulinum toxin injections may also be used to reduce fibroblast activity and tension within and around the scar tissue.
These injections may be combined with laser therapy as part of a comprehensive scar treatment plan.
Surgical Scar Revision and Contracture Release
In more severe cases, surgery may be recommended to improve scar appearance or restore movement.
Surgical scar revision may involve removing or repositioning scar tissue to create a more favourable healing pattern, or tissue expansion with flap reconstruction to remove extensive burn scar areas that are restricting movement and mobility.
Surgery is typically considered when conservative scar treatments are insufficient or when the scar significantly affects movement or daily activities.
Silicone Scar Therapy
One of the main mechanisms of silicone scar therapy involves reducing transepidermal water loss (TEWL) from the scar. When scar tissue loses too much moisture, the upper-most layer of skin called the keratinocytes become destabilised and the scar more likely stimulated to produce excessive abnormal collage. This will contribute to hypertrophic scars or keloids. Silicone sheets and gels help maintain hydration within the scar, regulating collagen activity during the healing process. This, in turn, helps reduce scar thickness and improve its overall appearance over time.
Dr Pearlie carefully selects silicone sheets of the appropriate thickness:
- Sheets that are too thin may lack sufficient occlusive effect to adequately hydrate the scar.
- Sheets that are too thick may not contour well or may lift off easily, reducing their effectiveness.
Using silicone sheets of the correct thickness ensures consistent contact, better hydration, and improved scar outcomes. Silicone therapy is typically started once the wound has fully healed and may be continued for several months as part of long-term scar management.
When should I see a doctor for burn scars?
You can see a scar specialist for burn scars if it bothers you, be it from the symptoms of pain and itching to disliking its appearance. The key is to seek treatment early.

Why consider burn scar treatment?
Burn scars can affect more than just appearance. Unlike surgical scars, burn injuries usually damage multiple layers of skin and surrounding tissue. Because of this, burn scars are more likely to develop into hypertrophic scars, keloids or scar contractures.
Physically, burn scars may cause itch, pain, sensitivity or tightness, and in some cases may restrict movement when located near joints. Certain scars may also remain inflamed or repeatedly irritated, which can cause ongoing discomfort.
Beyond the physical symptoms, burn scars can also carry significant emotional impact. The injury could be from a traumatic event, whether from a domestic accident, workplace injury or fire. Visible scars, particularly on areas such as the face, neck or hands, may affect confidence, body image and social interactions.
For these reasons, burn scar treatment is not purely cosmetic. Early and appropriate scar management can help improve both the function and appearance of the scar, supporting physical and emotional recovery.
Delaying treatment or relying only on over-the-counter creams may limit improvement. Early assessment by a plastic surgeon experienced in burn scar management can help identify suitable treatment options and guide a personalised treatment plan.
The goal of burn scar treatment is to help the scar become:
- Flatter
- Softer
- Less noticeable
- More comfortable
- Less likely to tighten or worsen over time
With appropriate treatment, many burn scars can be improved in both appearance and function.

Frequently Asked
Questions
When should I start burn scar treatment after a burn has healed?
Ideally, start burn scar treatment as soon as the wound has fully healed. However, it is important to understand that the final scar outcome is influenced even earlier, by how quickly the burn wound was attended to and how well it was managed during the acute healing phase.
Burns that receive prompt medical care, appropriate dressings, infection control, and heal within 2–3 weeks generally form less severe scars. In contrast, delayed treatment, wound infections, or prolonged healing significantly increase the risk of hypertrophic scars, keloids, and contractures.
Once the wound has healed, early scar management will highly influence outcome because immature scars respond best to treatment. Starting silicone scar sheets, silicone gel, compression therapy, and early vascular laser treatment can reduce inflammation and lower the risk of thick, raised scarring.
Can laser treatment for old burn scars still improve the scar?
Yes. Laser scar treatment in Singapore can improve both old and mature burn scars.
For thick or stiff scars, fractional CO₂ laser helps remodel collagen, soften scar tissue, and improve texture. If redness persists, a vascular laser can reduce residual inflammation. While burn scars cannot be completely removed, laser scar treatment can significantly improve their appearance, pliability and comfort.
What results can I realistically expect from burn scar treatment?
Burn scar treatment aims for improvement in appearance of the scar to try and make them as minimally obvious as possible and resolve any disturbing symptoms like pain and itching, but realistically, a scar cannot disappear.
With appropriate hypertrophic scar treatment or keloid treatment, scars can become:
- Flatter
- Softer
- Less red
- Less pigmented
- More flexible
- Less itchy or painful
Results depend on burn depth, healing time, infection history, and how early scar treatment was started. Earlier intervention generally produces better cosmetic and functional results.
Which treatments are used for thick or raised burn scars?
Thick or raised burn scars (hypertrophic scars and keloids) often require combination therapy, including:
- Silicone scar sheets or gel
- Compression therapy
- Intralesional steroid injections
- Botox injections to reduce fibroblast activity
- Vascular laser treatment for red, inflamed scars
- Fractional CO₂ laser for scar remodelling
- Surgical scar revision in selected cases
A personalised treatment plan by a female plastic surgeon experienced in burn scar treatment Singapore is important for optimal results.
How do you treat hyperpigmentation after a burn?
Hyperpigmentation after a burn is common, especially in Asian skin.
Treatment options include:
- Strict sun protection (topical and oral recommended)
- Medical-grade topical lightening creams
- Pigment-specific laser treatment
Laser settings must be carefully selected to avoid worsening pigmentation. Expert assessment is essential in darker skin types.
Are there risks like darkening or lightening of the skin after burn scar treatment?
Yes. Possible risks include:
- Post-inflammatory hyperpigmentation (darkening)
- Hypopigmentation (lightening)
The risk depends on skin type, scar stage, and the type of laser or injection used. Using inappropriate laser settings, treating scars at the wrong stage or inadequate post treatment care, may increase complications and worsen the appearance of the scar.
