Scar reduction treatments

Actual patient Hope Dermatology


This is a common question from patients.  Firstly in our assessment of scars, we have to assess the patient as a whole. Every scar in every patient is managed differently and there are lots of variables to consider.

These are the types of questions we need answers to before prescribing a scar reduction plan.

  • How old is the patient? If the patient is a young child, the scar may enlarge with their natural growth and can stretch. Older patients tend to heal up better from surgical scars as there is less tension in the skin.
  • What is the scar from? A traumatic fall? a burn? an acne scar? or a surgical scar? Each of these types of injuries will result in different types of scars. If the scar is from acne (for example), there needs to be complete control of any breakouts of acne before we then tackle the scarring. There is no point addressing the scarring without treating the new bouts of acne.
  • Where is the scar? Certain areas on the body will scar more severely than other areas. In general, areas of poor scarring include the chest, upper arms/shoulders and upper back as these are areas where there is the most tension on the skin and these areas can be prone to keloid or hypertrophic scarring
  • What skin phototype is the patient? Typically patients with darker skin types will scar worse than people with fairer skin types. However, a true scar is not to be confused with post inflammatory hyper-pigmentation (PIH). This PIH is more common in darker skinned people and PIH should resolve without scarring but it can take 6 months or more to resolve in darker skinned people. Hence PIH differs to scarring as often with PIH there is no need for any treatment other than waiting for spontaneous resolution.
  • How long has the scar been present for? Scars can take about 2 years before they fully mature and transition from the acute red/pink colour to the long-term pale/white colour. So if a scar is only recent, it should be explained to the patient that there is a fair chance the scar will improve naturally without any treatment.
  • Could the scar actually be a skin cancer? There are some types of skin cancers that can mimic scar and for this reason, patients ignore the lesion. If there is a scar area or an ulcer that is worsening with time, we should alway consider scar-like skin cancer. The most common one would be sclerosing basal cell carcinoma. This type of skin cancer can be difficult to treat; particularly as patients may not seek treatment quickly.
  • Is the patient taking any medication? Some medications can delay wound healing and hence continuation of such medication needs to be carefully considered in the context of scarring.
  • Is the patient using sunscreen?  UV exposure not only increases the risk of and darkens any existing PIH in a scar, it also impedes our natural wound healing response leading to a poorer cosmetic outcome.
  • Is the patient allergic to any wound dressings? Avoiding irritants in the area, whether it be a traumatic or surgical scar,  will enable better healing without causing additional inflammation in the surrounding skin. If the wound is carefully looked after in the early stages of healing, the risk of a scar, or the extent of scarring can be minimised.
  • Is the patient using any medical grade skin care? This is particularly relevant to facial scars or acne scars and depending on the evolution of the scar (i.e. new, old, currently being treated) active skincare such as Vitamin A creams or prescription fading creams such as Hydroquinone preparations can either aid or hinder healing and must be used under the supervision of an experienced practitioner.

Treatments for scarring

Effective treatment for scarring involves accurate assessment of the scar.

  • Is it tethered to the underlying tissues? If so, subcision, where there is manual release of the tethered tissue could be appropriate.
  • Box car, rolling, ice pick – these are all terms for the different types of scarring in acne. Acne scarring can be treated by a number of modalities including Fractionated laser, Radio frequency, Fractional radio frequency or Skin needling.  Each of these vary with respect to downtime, discomfort, cost, result and suitability of skin type.
  • Keloid scar? Intralesional steroid injections could be appropriate to flatten the areas and improve the pain of the scar for patients, as often patients often have exquisitely sensitive skin over their keloid area. The dermatologist will decide on the strength of the steroid injection needed. This is important as too weak a strength will result in no change in the keloid scar; and too concentrated an injection will mean skin dipping where the injection is. Hence injections should be performed carefully by experienced doctors. These injections are usually performed every 4-6 weeks until good cosmetic result is seen.
  • PIH or post-inflammatory erythema?  As mentioned, assessment is important to not only ensure the correct treatment is selected but in some instances, no treatment is in fact the best treatment.  Patients often present looking to improve their self-perceived acne scars when in fact the skin is still healing from recent breakouts and any post-inflammatory redness will fade with time without intervention as will PIH.  In saying this, we can often speed up this process with vascular laser (for a red scar) and prescription fading creams/skin needling/laser for pigmented scars.

We offer a variety of treatments for many types of scars here at Hope Dermatology and encourage you to book with our team of Specialist dermatologists and cosmetic team to discuss the most appropriate treatment plan for you and your skin.

Treating freckles and pigmentation

Autumn is officially here! And with the cooler weather, lots of our patients are wanting laser and treatment for their pigmented and blotchy skin. Our laser nurse Kristie gives us an overview of pigmentation…Freckles, pigment, sunspots…

What’s the difference!?


Kristie Phillips - Hope Dermatology

“In my 18 years of lasering I have often been asked this very question, and frequently in general conversation the terms “freckle”, “pigment” and “age spot” get bandied around interchangeably.

Whilst as a consumer, you probably don’t need to know the ins and out of what constitutes a freckle versus a sun spot, or whether you have sun damage or melasma it is important to understand there IS a difference and this can be VERY important when it comes to treatment”.


PIGMENT essentially refers to the colour of the skin and is determined by the level of melanin, produced by melanocytes. Melanin production is determined by racial origin and sun exposure. People with dark skin produce more melanin than those who are fair skinned, and exposure to sun and UV stimulates our melanocytes to produce more melanin, resulting in a tan. Generally when people are seeking treatment for their pigmentation, we are referring to excess and uneven pigment.

MELASMA is a chronic skin disorder that results in a symmetrical, blotchy, darkening of the skin that can be both difficult to treat and distressing for sufferers. It commonly affects women more so than men, manifesting around the ages of 20-40. It results from the production of melanin by melanocytes, as with a tan, but is an overstimulation of melanin that persists long term (often despite our best efforts!) The cause of melasma can be complex and can have a genetic predisposition. Common triggers can include sun exposure, pregnancy, hormone therapy such as the oral contraceptive pill, other medications and inflammation from cosmetics such as perfumes or soaps and so strict avoidance of these is vital in treatment.

FRECKLES (medically we call them ephelides just to add another term into the mix) present as small, flat brown lesions on sun exposed areas of the body such as the face, shoulders, arms etc and are common in people with fair skin and red heads. Freckles are the result of sun exposure which again is stimulating our melanocytes to produce melanin, which then accumulates locally in the superficial skin cells (keratinocytes). They typically darken in summer (with sun exposure) and fade in winter (due the natural exfoliation and replacement of the keratinocytes).

SUN SPOTS / AGE SPOTS / LIVER SPOTS etc etc are all terms used to describe SOLAR LENTIGINES. Like freckles, solar lentigines are benign dark patches in the skin, as a result of sun induced melanin production and localised proliferation within the keratinocytes.   Unlike freckles, they do not fade in winter and tend to present in people over the age of 40 and accumulate with continued sun exposure, hence the terms “sun damage” and “aged spots”. They have NOTHING to do with your liver.

So how do we treat them? Well first I would always suggest a skin check with the dermatologist to diagnose your skin condition and rule out the myriad of OTHER brown spots and skin lesions and potential skin cancers.

Beyond that…

Prevention – with daily (rain, hail or shine) use of an SPF 50+.

Repair  – with good quality, cosmeceutical skincare (think AHA, Vit A, Vit B, Vit C etc etc).

Remove – generally with laser. There are a variety of lasers available to treat various types of pigment irregularities and a consultation is a must.
