Scar Treatment

Scar Treatment

There are many types of scars and each requires specific treatments. Generally, scars are classified according to the cause of the injury or the type of scars. Scars are difficult to erase completely – most treatments are to improve the appearance

Treatment of scars

Treatment of scars depends on the aetiology and type of scars. Sometimes a combination of treatments are needed to treat a single scar

Treatments available to treat scars

  • Prescription creams: to improve the colour and the texture
  • Corticosteroid injection/tape/ointment
  • Non steroid injections: 5FU, interferon, bleomycin, neurotoxins
  • Chemical peels
  • Chemical reconstruction of skin scars (TCA CROSS)
  • Cryotherapy: liquid nitrogen
  • Light therapy : IPL, LED
  • Fractional Laser scar resurfacing : CO2laser, Fraxel laser, YouLaserMT
  • Fractional Radiofrequency
  • Jet volumetric remodelling (Enerjet )
  • Thermo- mechanical remodelling (Tixel Pro)
  • Surgery: subcision, punch excision, punch elevation, scar revision
  • Dermal filler injections

Treatment of superficial scars with chemical peels

Chemical agents are applied on the scars to improve the colour or the texture of superficial scars. Sometimes several sessions are needed

Treatment of pitted scars with chemical reconstruction of skin scars (TCA CROSS)

A strong chemical (usually trichloroacetic acid) is applied to the apex of the scars. The chemical removes some of the scar tissue and stimulate new collagen below the scars. Several treatments at 4-8 weeks are done till the scars are flat. Sometimes TCA CROSS is done before scar resurfacing or remodelling by the Youlaser MT or Enerjet or Tixel Pro.

Advantages of TCA CROSS

  • Simple, safe and effective treatment
  • Minimal downtime

Treatment of keloid or hypertrophic scars with cryotherapy( liquid nitrogen)

Liquid nitrogen is sprayed onto keloid or hypertrophic scars to soften the scars before intralesional injection. Sometimes a probe is inserted into the scar to deliver liquid nitrogen to shrink the scar

Treatment of coloured or superficial scars with light therapy

Certain wavelengths of lights are applied onto scars to improve the red or brown scars and also to improve the texture. The lights can be a broad band light (IPL) or  a specific wavelength (LED light).

Advantages of light therapy

  • Non-invasive and effective for certain scars
  • No downtime

Treatment of scars with fractional laser scar resurfacing

Fractional lasers can resurface both depressed and raised scars.

  • They can be either the ablative lasers (CO2laser, Erbium-YAG laser) or the  non-ablative lasers (Solta Fraxel Dual) or the combined ablative and non-ablative lasers (YouLaser MT, Sciton Halo).
  • Thousands of microscopic laser columns penetrate deep into the scars, to remove old and damaged cells.
  • The adjacent skin between the lasered columns is kept intact – this allows for better and faster healing and minimal side-effects. Eventually this scar too is replaced with new tissue

Treatment of scars with fractional radiofrequency

Fractional radiofrequency (RF) works by passing a current through the scar and surrounding dermis at a pre-set depth to produce small thermal wounds in the scar and surrounding skin which in turn, stimulates dermal remodelling to produce new collagen and soften scar defects. Combining RF with microneedling allows the RF energy to penetrate deeper into the scars and gives a better result

Treatment of scars with Jet Volumetric Remodelling (JVR): Enerjet Pro 2.0

  • The Enerjet Pro uses Jet Volumetric Remodeling (JVR) technology – a high-pressure jet technology to simultaneously produce micro-trauma and introduce hyaluronic acid or any healing agents deep into the dermal layer of the skin and scar.
  • The synergy between the two effects sets in motion a cascade healing process, resulting in scar remodelling and skin hydration

Treatment of scars with Thermo-Mechanical Remodelling (Tixel Pro)

  • The Tixel Pro uses thermal mechanical ablation to transfer heat energy to the scars and surrounding skin.
  • A template with cones is heated (at 400 degree celsius) and this is stamped onto the scars and skin to create tiny microscopic columns.
  • This heat stimulates the skin to generate collagen and elastic fibres and hence improve skin surface and scar texture.

Treatment of scars with surgery

There are many different surgical procedures to improve scar. Among them are:

  • Subcision: This is a minor surgical procedure to release the attachments of deep fixed scars from the surrounding skin. Once the attachments are released, new collagen is able to slowly elevate the scars
  • Scar excision: The scars are either punched out or excised and replaced with a linear surgical scar. This scar can eventually be resurfaced with a laser
  • Scar elevation: The scars are partially excised and then elevated to be flush with the skin surface
  • Scar revision: The scar is often excised and revised to improve the cosmesis of the scar. Scar revision is also used to reduce tension in a scar

Treatment of scars with dermal fillers

  • Dermal fillers are injected below the scar to elevate the scars initially and to stimulate collagen and elastin to remodel the scars.
  • The fillers can be hyaluronic acid, growth factors or other healing agents.
  • Fibrotic scars are subcised before the injection of dermal fillers.
  • Dermal fillers improve scars within a short period while waiting for the other procedures to work

Scars can be classified according to the causative factors and each type of scars may require specific treatments

Types of scars commonly seen in our clinic

  • Acne scars
  • Keloids and hypertrophic scars
  • Post-inflammatory scars
  • Traumatic scars
  • Post-surgical scars

Acne scars

Acne scars can be present during the active acne phase or when acne is healing. Some are temporary and improves on their own while others remain permanent and require treatments

Types of acne scars

  • Flat brown scars
  • Red healing scars
  • Depressed and pitted scars
  • Raise soft scars on the nose
  • Keloids scars

Treatment of acne scars

  • Prescription creams
  • Chemical peels
  • Red scars: Treatment with pulse dye V beam laser, Excel V laser, BBL light treatment
  • Brown scars: Picoway laser, Fraxel Dual laser
  • Laser scar resurfacing: CO2laser, Fraxel laser, YoulaserMT, Picoway Resolve Laser
  • Jet volumetric remodelling (Enerjet )
  • Thermo- mechanical remodelling (Tixel Pro)
  • Chemical reconstruction of skin scars (TCA CROSS)
  • Surgery: subcision, punch excision, punch elevation, scar revision

Keloid and hypertrophic scars

Keloid and hypertrophic scars are caused by skin injury and irritation and the subsequent abnormal wound healing

Causes of keloid and hypertropic scars

  • After skin injury and burns
  • After skin surgery
  • After skin infection: acne, folliculitis, chickenpox
  • After skin inflammation: insect bites

Post-inflammatory scars

Post-inflammatory scars occur after skin inflammation or skin treatment. It can be hypopigmentation or hyperpigmentation scars
