Scar Revision

About Scar Revision

Following injury or an operation, a typical scar develops as quite red for 3-6 months before settling as a light coloured flat scar.  However, if a delicate balance is not achieved during the healing process after injury or operation, a scar may display abnormalities resulting in more noticeable scars that can be itchy and painful as well as unsightly.

There are 3 types of abnormal scars:

Keloid – usually red and raised and extends onto uninjured skin that surrounds the original site of operation or injury. Develops due to an overgrowth of tissue. If a keloid scar is removed, it will often recur.

Hypertrophic – usually raised, red and painless.

Contracture – These scars tighten skin, which can impair your ability to move. Can occur if your skin has been burnt.

Abnormal scar appearances can be improved with both nonsurgical treatments and or surgery.

Non-surgical treatment

In some cases, cortisone injections can improve the scar appearance by reducing scar thickness, redness and/or itching. Otherwise, surgery will be required.


The surgical technique selected depends on the type, size and site of the scar. Options include:

  • Completely removing the scar and then mending the wound again
  • Taking skin from other areas to cover up the areas of the scar (also known as skin “flaps” or “grafts”)
  • Making the scar less noticeable by changing the direction of the scar (the z-plasty technique)

Meticulous technique, both in the removal of the existing scar and also the repair (suturing) of the wound is paramount. The post-operative care of the wound and removal of sutures is also very important.


How can I help minimise my scar from surgery?

A good scar management routine usually involves a combination of applying silicone gel, massaging with bio oil, using tape on the wound and keeping the area out of the sun for several months post-surgery. The exact routine prescribed will depend on the procedure performed, the area of the body and your age and skin type. Diligent adherence to the routine is your best chance to minimise scarring.

Why do you recommend silicone for scar minimisation?

We recommend a silicone-based scar gel as there is strong scientific evidence that silicone improves scar outcomes.

What can I do to help reduce pain whilst my scar is healing?

Massaging the scar daily can help reduce sensitivity and pain – scars can be uncomfortable and painful for the first month after surgery as they heal.

Will the sun make scars worse?

The sun does not technically make the scar worse, however, your scar will be more susceptible to sun damage than undamaged skin. Hence it is important to wear sun protection daily on the scar.

How long does the scar healing process take?

The scar healing process will generally take between 9-12 months after which point it will become a mature, pale scar if it has healed well.

What can be done if I develop a keloid or hypertrophic scar?

A cortisone injection can be useful in treating hypertrophic and keloid scars as it can help dissolve excess collagen and create a flattened appearance.

When will I know if I need scar revision surgery?

If you develop a complication such as stretching, keloid or hypertrophic scarring, this will normally be evident by the 6-month mark, which is a good time to consider scar revision surgery.

Will I have no scar after scar revision surgery?

No scar can be completely eradicated, however every effort is taken to significantly improve its appearance.

How long is my recovery post-surgery?

If Scar revision surgery is required, your sutures are usually removed 5-14 days post-surgery. At this appointment, our practice nurse will advise you on when and how to start your scar management protocol at home.

Medical terms

Typical Scar: A typical scar that is healing well may develop as quite red for 3-6 months before settling as a light-coloured, flat scar by about 9-12 months once healing is complete

Keloid Scar: Develops due to an overgrowth of tissue – usually red and raised and extends onto uninjured skin that surrounds the original site of operation or injury. If a keloid scar is removed it will often recur

Hypertrophic Scar: Usually raised, red and painless

Contracture Scars: This can occur if your skin has been burnt. These scars tighten skin, which can impair your ability to move and may also go deeper, affecting muscles and nerves


Our Surgeons & Anaesthetists charge out-of-pocket fees for surgery done in the private hospital.

Because the length and complexity of the different surgical techniques are so vast, you will be given an estimate of costings after your consultation.
