Your acne scar type, scar grade, existing skin condition are factors that determine the best approach to acne scar resurfacing.  Over the past decade, a greater understanding of the science of acne scarring has led to the development of various techniques to address the various acne scars types and grades. 



Every single case of acne scar is unique and everyone is treated individually based on your acne scar morphology, scar type and your treatment goals. With a carefully planned patient-tailored combination approach, this will lead to more significant improvements in your acne scar appearance. Drawing upon the latest acne scar techniques coupled with his wealth of experience, Dr. Ng will help craft a personalised treatment plan for you to help repair your acne scars and restore your skin.

What Causes Acne Scars?

Scar are a consequence to trauma to the skin, and acne scars are no exception. While acne scarring is common to acne patients, it can directly affect an individual’s confidence and quality of life.

  1. Inflammation as a consequence of acne drives a modified wound healing response within the skin. This disparity between collagen breakdown and collagen synthesis contributes to the type of acne scars you would have. Acne that is more severe and prolonged will lead to more severe acne scar formation.
  2. The imbalance of the skin remodelling will result in an inadequate healing response. When there is more collagen breakdown than synthesis, depressed atrophic acne scars will be more apparent. On the other hand, over-synthesis of collagen will result in more hypertrophic or keloid scarring.

A skin analysis under direct and indirect lighting will determine the acne scar type, acne scar grade and depth. A careful examination personalises your treatment plan based of your unique acne scar type and skin condition.

The treatment stage involves treating your acne scar subtypes with evidence based procedures. These can range from TCA CROSS, subcision, fractional resurfacing lasers and RF microneedling devices.


Acne is one of the most common inflammatory skin conditions globally. It is the 8th most common disease to affect individuals worldwide. Despite affecting more than 85% of adolescents, acne may persist well into adulthood. Conversely, the adult-onset acne variant tends to be challenging to treat as it tends to be more persistent. 

One of the most distressing consequences of acne is acne scarring. Acne scarring affects more than 90% of acne sufferers, and about 30% of cases are classified as severe. The effects of acne scarring pervade across one’s psychological well-being, social life, academic performance and employment opportunities. Hence, effective treatments for acne scar removal in Singapore are essential to prevent and reduce the appearance of acne scars and are always part of your treatment plan.

While it is of interest to individuals to receive early treatment for their acne breakouts, they should also be aware of the acne scar treatments available at the moment.

What are the types of Acne Scars?

Acne scar types are classified into two broad categories: atrophic and hypertrophic/keloid scars. While atrophic acne scars make up more than 80% of cases of acne scars, the hypertrophic and keloidal scar variants are commonly encountered in our local population.

Atrophic scars are subdivided into ice pick, rolling and boxcar scars. Amongst the atrophic acne scars subtypes, ice pick scars are most common (60-70%), followed by boxcar scars (20-30%) and rolling scars (15-25%).

Acne scars are also graded based on their colour, whether red (erythema), brown (hyperpigmentation) or white (hypopigmentation). The degree to which the scar appears to flatten when you stretch the skin gives some indication of the depth of your scar.

In practice, most individuals would have a mixture of the different scar types, scar depths and scar colour. The treatment objective would be to identify the predominant scar type so that the most suitable acne scar removal treatments can be recommended.

A customized approach to acne scars

Every individual is unique, and so will the acne scar type and distribution. There is no standardised treatment for your acne scars. The acne scars treatment is a dynamic process because the response to treatment, scar types, previous treatments, skin type/condition and downtime greatly differs across individuals. 

What has been agreed on by a recent international consensus on acne scars is that a combined treatment approach to tackle mixed acne scarring will yield better results.

The numerous types of treatment for acne scar removal in Singapore can be confusing. Indeed, acne scar revision can be a complex process as often you have more than two different scar types requiring different treatments. There is no single method to treat the various scar types. For example, fractional ablative lasers such as CO2 laser will not improve deep ice pick scars and tethered scars very much. On the other hand, surgical procedures like subcision is not suitable for superficial boxcars and rolling scars.

Generally, the treatment of pigmentation and erythema (redness) is tackled with first to improve the skin tone. Subsequently, deep acne scars (if any) removal treatments are performed to detach the underlying fibrous tissue, stimulate collagen and enhance dermal remodelling before performing a full face fractional resurfacing to even out your skin tone and texture. 

The treatment options will also have to depend on your skin type and colour. Individuals with a darker skin tone will benefit from gentler treatments over time, as there is an increased risk of pigmentation with overly aggressive treatments.

Treatment Recommendation:

  • Subcision of deep tethered scars should be done first to release the deep scars
  • Fractional resurfacing
  • Fillers or Rejuran S should be done four weeks after fractional resurfacing

Mild Acne Scars with Hyperpigmentation

Treatment Recommendation:

  • Pico laser to reduce post-inflammatory hyperpigmentation first.
  • Fractional resurfacing with Pico-second laser, INFINI, and Genius treatments are safer to minimise epidermal damage for individuals with darker skin phototypes.

Can My Acne Scars Be Treated While On Oral Isotretinoin?

Spring LK et al. (2017)

For many years, it was the view that actively treating acne scars whilst on oral isotretinoin could lead to abnormal scarring and poor wound healing. Individuals were told to wait at least 6 to 12 months before starting acne scar procedures. This led to delays in initiating acne scars treatment and prolonging the negative physical, emotional and social implications associated with acne scars.

However, an expert consensus in 2017 found that it was not necessary to halt all forms of acne scars treatment.

Treatments that are not recommended to be carried out while on oral isotretinoin or shortly after completely oral isotretinoin therapy include:

  • Mechanical dermabrasion
  • Fully Ablative Laser 

Treatments that do not have compelling evidence to support delaying treatment and may indeed be safely carried out include:

  • Manual dermabrasion
  • Superficial chemical peels
  • Fractional ablative lasers
  • Fractional non-ablative lasers
  • Laser hair removal
  • Skin surgery

Can My Acne Scars Be Treated While Having Acne?

Individuals who have active acne are at an increased risk of developing acne scars and early intervention is recommended.  Individuals with moderately-severe Acne Vulgaris who are often on oral and topical medications may consider acne scars treatment to reduce inflammation, reduce scarring potential and increase the effectiveness of the acne medication.

Various laser and energy based devices may be used concurrently and safely to prevent further scarring and enhance the effects of acne medication. These may include Pulsed Dye Lasers, Nd:YAG Lasers, Fractional ablative and non-ablative lasers and Fractional RF microneedling. Fractional RF microneedling treatment such as the INFINI and Genius have been found to reduce acne lesions and sebum production and improve the appearance of acne scars.

What is the downtime from the Acne Scar Removal program?

This depends on the type of treatments, your skin type and individual healing times. While some treatments such as fillers have very little downtime, some are associated with more significant social downtime, which requires treatment to be planned in advance to suit your schedule.

With a focus on efficacy and safety, we seek to offer treatments planned around your schedule, fitting with your recovery and lifestyle.


  • Dermal Fillers: Usually minimal downtimes. Mild swelling post fillers for 2-3 days. Bruising is usually mild and fades in 1-2 weeks.
  • Subcision: Redness and swelling lasts a few days, bruising may take at least 1-2 weeks to subside.
  • TCA CROSS: Redness and swelling lasts a few days, scabs will typically fall off within a week.
  • Fractional Resurfacing (Pico, Genius, INFINI) : Redness and swelling lasts 2-3 days. Most individuals heal within 5-7 days. Downtime is longer with more intense treatment parameters.
