Fractional radiofrequency is a non-laser method of scar removal, best suited for early, mild to moderate scarring.

Laser Dermatologists specialise in the treatment of acne scars and we are at the forefront of technology. The clinic has 5 types of Fractional skin resurfacing procedures. The method of fractional treatment will depend on your skin type, scar type and downtime.

Fractional radiofrequency is a non-laser method of scar removal, best suited for early, mild to moderate scarring, whilst fractional C02 lasers are best for moderate to severe scarring. Erbium fractional laser is an intermediate fractional laser used in darker skin types.

Fractional laser resurfacing, as the name suggest, treats ‘fractions’ of skin enabling quicker recovery for patients. Most patients will benefit from a series of fractional laser treatments.


  • Fractional lasers such as Fraxel, CO2 RE, and Profractional are at the forefront of acne scar treatments
  • Fractional laser treats only a ‘fraction of skin’ which speeds up recovery time and lowers the risks of full laser resurfacing
  • Scar improvements of up to 70% can be seen after 3-4 treatments
  • Side effects are rare and the procedure is very well tolerated
  • Recovery time can be tailored according to each patient, typically 3-5 days
  • Erbium Fractional laser has less downtime compared to CO2 and is best suited for darker skin types
  • CO2 RE Fractional laser has a longer downtime, however it delivers better results compared to Erbium Fractional laser in lighter skin types
  • Fraxel Laser is excellent all round laser and can be used on all skin types. 3-5 treatments are needed for best results
  • Non –laser fractional treatments such as RadioFrequency will deliver little or no downtime, however works best for early and very mild scars
  • Each patient will have a unique pattern of acne scarring, and a tailored program will give the best possible results
  • Skin needling is not fractional resurfacing, however this outdated procedure can be considered as the genesis of fractional skin treatments

Mixed Acne Scars

Rolling and depressed acne scars

Box car scars

Fracionated laser treatment (ProFractional, Fraxel, CO2 RE) is the latest laser for acne scarring. The laser produces thousands of tiny ‘ablation’ zones in the treated areas. Each zone is the diameter of a shaft of hair, however these columns extend deep into middle layer of the skin- where scars lie. Laser targets the scarred areas and old collagen, but also leaves areas of healthy tissue to regenerate. This fractional treatment allows your skin to heal much quicker than if the entire surface was treated at once.

Fractional laser treatment allows less patient downtime and side effects but still delivers great results.

The Acne Specialist Clinic at Westside laser Dermatology has several fractional devices for acne scarring. Our Specialist will carefully assess your scar type, skin type (skin colour), age of your scars, and take into consideration your downtime and budget to provide a solution that will work for you.

Scar revision is a highly complex and variable procedure, and the first step is an accurate assessment and ‘map’ of you.

As a guide -

CO2 RE Fractional laser

One of the best fractional lasers for mild to severe scars. Suits fair skin types, but can treat type 3 skin. Downtime approaching 7 days.

Fraxel Dual Fractional laser

The laser that started it all. An all round laser that can treat most scar types and nearly all skin types. Downtime of 3-8 days. Will need 3-5 treatments.

Erbium Profractional laser

Great for mild to severe scarring, best for darker skin types. Downtime of 3-5 days. Can be combined with CO2 Fractional laser.

RF Subablative

Non laser, RadioFrequency Fractional treatment- Great for all skin types, good for early scarring. Can be used for mild to moderate scars or as part of our Synergy Method for acne scars. Downtime of 0-2 days depending on energy settings.

Synergy Method of acne scar revision

Combination of fractional lasers, TCA Cross, and RadioFrequency to give the best possible outcome. We may elect to use a combination of fractional devices during different stages of scar revision.

Treatment Downtime Skin type - colour Scar severity Projected scar improvement Costs
CO2 Fractional laser 3-6 days 1,2,3 Mild to severe scarring ++++ $750 - $1200 per treatment
CO2 Fractional +erbium resurface 4-8 days 1,2, 2.5 Mild to severe scarring ++++++ $1500 - $4000
Erbium fractional laser 3-5 days 1-5 Mild to severe scarring +++ $750 - $1200 per treatment

Fraxel is an excellent all round laser than can treat nearly all forms of acne scars including atrophic, box car, and rolling scars, in all skin types. Fraxel laser resurfacing also has a lesser downtime compared to CO2 CORE Fractional laser.

Specialists at Westside Laser Dermatology will always advise you as to what type of laser is best for your acne scars. Our collection of fractional lasers ensures that you will have the absolute best treatment for your acne scars.

Procedures are performed in one of our three laser suites at Westside Laser Dermatology by Specialist Dermatologist, assisted by a Laser Nurse. Local anaesthetic cream is applied 45 minutes prior to treatment. Just before the procedure, the cream is wiped off and cleansed with an antibacterial solution. Eyeshields are worn during the treatment. A computer-guided scanner is placed over the treated area and the laser is applied. The procedure takes 15 to 30 minutes to perform.

Immediately after Fractional laser

2 days after light - medium fractional laser

Laser treatment is well tolerated in the majority of patients. We often combine some mild "twilight sedation" as well as numbing cream to ensure that patients are comfortable throughout laser treatments. As a guide, the majority of patients rate the pain as 2 out of 10 on the pain scale.

Immediately after laser the skin is red, swollen and feels like sunburn. Simple panadol can alleviate any pain, and ice packs can cool the treated skin. Downtime or recovery time will depend on several factors including the extent and depth of laser treatment as well as the type of laser we use.  As a guide recovery times range from 3 days to 7 days. This will be discussed in detail prior to any laser treatments.

Significant acne scarring prior to treatment

Immediately following one light pass of Fractional Laser. Fractionation, treats a specified percentage of skin. Treatments can be non - aggressive with quick recovery times.

3 days after laser. Complete healing is seen at day 6. Swelling has decreased. Best results are seen 2-3 months after treatment- the time it takes for new collagen to reform. 2-4 treatments are recommended. Dr Davin Lim

Before and after treatment

The number of acne laser scar treatments will vary between patients depending on the depth and types of scars. Two other factors play an important role in the assessment of acne scars- skin type (skin colour) as well as downtime.

As a guide we recommend 3-4 laser treatments for the best results. These treatments are spaced at intervals of 2-3 months apart. Your laser dermatologist will give you an estimate of expected improvement with each treatment.

The choice of which laser we elect to use will depend on your skin type, scar severity and downtime. Laser dermatologists will often use multiple lasers in the one treatments session- this provides the best outcome for the patient. The use of multiple treatment methods forms the basis of our Synergy Program for acne scar revision.

All laser treatments are performed by Specialist Dermatologists and laser nurses with years of experience. Acne scar specialist train as doctors, then undergo additional training as Skin Specialist (Dermatologists), they undertake subspecialist training is scar revision techniques and laser surgery. Expertise, experience and training ensure patients are in the best possible hands.

RadioFrequency or RF treatment for acne scars is the newest method of acne scar removal. This treatment is not a laser-based method of fractional skin resurfacing, but it involves the use of radio waves to target scarred collagen beneath the skin’s surface. RF is a form of FRACTIONAL SKIN treatment, with out the downtime of lasers. RF is best suited for early onset mild to moderate acne scar. Early scarring can be defined as acne scars less than 3 months old. RF can be combined with anti-acne treatments. 3-5 treatments are ideally needed for optimal results. Fractional RF is the safest method of acne scar removal in darker skin types.

The recovery from RF is very quick, and will depend on the power setting we use. As a guide low setting RF subablative- downtime of up to 12-16 hours. High energy RF for acne scars will have a 48 hours recovery.

Note that RF treatments are best for early mild acne scars, in patients who have little downtime to spare. Fractional Laser treatments such as Fraxel, Erbium or CO2- Fraxel is a better treatment for more severe scarring. Once again a tailored program, depending on scar type, skin type and down time will give the best results.

The first step can be a daunting process for many patients. Our Specialist will assess your acne scars and provide solutions based upon individual assessment.

Acne scar treatment is a highly individualized treatment, and at the Acne Specialist Clinic we never approach scar removal with a ‘cookbook approach’. All treatments are tailored according to the patient’s scar type, skin type, downtime and budget.

Rest assured, the experience, training and equipment used at the Acne Specialist Clinic will ensure the best possible outcomes for all our patients.

Traditionally, fractional lasers have provided a safe and effective means of treating acne scarring in all skin types. We now have a variety of fractional devices to resurface acne scars. Skin needling was one of the first methods to provide fractional resurfacing, however this method is historical. Fraxel laser paved the way in 2005, followed by a variety of fractional methods. As the name suggest, treating skin area in fractions enables quicker healing times, and in darker skin patients it poses less risks.

With an array of fractional devices at the Clinic we can tailor downtime for the patient and weight the risks and benefits for each form of fractional treatment.

For results the CO2RE fractional laser is the ‘big gun’ in acne scar revision, however it has a longer downtime compared to erbium Scition Profractional laser. Erbium is an excellent method of fractional resurfacing in darker skin types, or when down time is an issue. Newer non-laser based subablative RadioFrequency fractional devices are useful for mild to moderate, early scarring. What device I choose is based upon scar type, skin type and downtime, and an individual assessment is needed for optimal outcomes.

Fractional lasers are not the be all to end all for acne scar revision – I often combine techniques such as subscision, TCA chemical peels and Full resurfacing for best patient outcomes. Fractional lasers form part of my Synergy Program for acne scars.
