Dermal Filler Acne Scars

Acne scars can be treated with subcision & dermal fillers. This provides instant acne scar reduction with no downtime. Fillers are best used when your immune system can not regenerate enough collagen or fat to replace volume changes associated with acne scars. I use many types of fillers including hyaluronic acid & collagen stimulating fillers, taking into account age of patient, types of scars as well as the location of scarring.

FactsFacts on Dermal Filler Acne Scars

  • Fillers are used to correct volume deficits due to scarring
  • FIllers are indicated when your immune system can not generate enough collagen
  • HA fillers last 18+ months
  • Collagen stimulating fillers last up to 5 yrs
  • Correcting age related volume loss is equally as important as addressing acne scars
  • Fillers give support to skin, thereby indirectly improving acne scars
  • Unlike lasers, soft tissue fillers have no recovery time

When are dermal fillers used to treat acne scars?

Dermal Filler Acne Scars

Dermal fillers are used in two situations. Firstly, if you are in a hurry to get immediate results with no downtime. Secondly, if your immune system can not generate enough collagen & or fat to correct depressions.

Most patients will have a mixture of acne scars. These include rolling, mixed, atrophic, tethered, & depressed scars. These scar types can respond to dermal fillers.

How to dermal fillers work?

Dermal fillers correct volume deficits due to loss of collagen & fat. Fillers are indicated in patients whose immune response can not stimulate enough tissue.

Lasers & radiofrequency can stimulate collagen-producing cells to start laying more collagen. The disadvantage of this process is that it takes time and several treatments for the best results. Downtime, meaning skin recovery can take between 2-10 days. Results from energy based devices like lasers & micro needling RF rely on your own immune system to stimulate collagen production – this means results are only seen after 6-8 weeks, and maximal at 3-4 months after the procedure.

If you can not remodel or regenerate collagen, the best solution is with dermal fillers.

In some patients, the immune system can not replace the volume loss due to both age & acne. Fillers are used to correct volume changes.

Are fillers permanent?

No, however they typically last 1.5 to 5 years in the context of acne scars. Like everyone else I want a permanent solution for acne scars. The fact remains that if your body’s immune system can not correct volume changes you are left with only 2 choices- namely dermal fillers or fat transfer.

Pros of fillers– 1 to 1 correct, meaning if I place one ml of volume, there will be at least one ml of correction. HA fillers are reversible should there be any over correction or injection into a blood vessel.

Dermal fillers give your immune system a helping hand to generate more collagen.

Cons of fillers– In some cases volume deficits can be large (upwards of 8 mls). In this situation fat may be a more cost effective solution. Fillers last 18 months to 3 years for hyaluronic acid brands, whilst some collagen stimulating fillers last up to 5 years

What is the newest bio-stimulatory injectable for acne scars?

In late 2022, Australia has a new product know as a bio-stimulatory injectable. It is made out of high & low molecular weight Hyaluronic Acid.

Unlike traditional HA dermal fillers, this one stimulates your own collagen & fat cells. This product can treat atrophic scars. 2-4 sessions are required for optimal outcomes.

This injectable stimulates your own body too produce collagen & connective tissue, improving atrophic scars.

What can I expect form biostimulator Hyaluronic Acid injections?

You can expect 10-50% improvement in acne scars after each treatment. Sessions are spaced 4-6 weeks apart. Optimal results are seen 8-16 weeks after the last treatment.

Bioremodulator – biostimulator injections are entry level acne scar treatments with no downtime.

This injectable is a cost effective way to treat acne scars. Each session cost $850 (2 ml of product, treatment by our specialist nurses).

Rolling & atrophic scars are suitable for this injectable. My clinical staff can guide you accordingly.
Boxcar & ice pick scars follow a different algorithm.

Do I mix different types of fillers for acne scars?

Yes. I use thick fillers for support, & thin fillers for filling fine areas such as the temples & tiny open pores. For most of my patients I use what I call a ‘layered technique’- support for deep scars, & finesses for fine scars. Hence I combine two types of cross-linked HA fillers.

I also combine collagen stimulating fillers with HA fillers. Additionally I also combine fat transfer, ASC (Adipose Stem Cells), with fillers.

Hybrid fillers are new in 2022. They have the most amount of data in the context of scar revision. The proper term is bio-stimulatory injectables. 

Davin’s Viewpoint On Dermal Fillers

I too want a permanent solution for patients. In the next 2 years there will be newer fillers entering the market offering longer duration, however as it stands they max out around 5 years.

In the early years, acne scar revision started off with full dermabrasion, followed by fully ablative lasers such as CO2 and Erbium. I started skin needling or skin rolling early in my career & introduced fractional laser resurfacing to my practice in 2006.

A decade later, the addition of new cross linked HA injectables  has given acne scar patients another modality to improve their scars. Acne scar revision is always based on 3 factors- acne scar type, skin type and downtime of the patient. Fillers are primarily used for atrophic, rolling, & tethered acne scars, and can be used in all skin types. This means skin colour does not play a rate limiting role for filler treatment.

Fillers have a clear and distinct advantage over lasers in that they provide ‘instant’ collagen & scar correction with no downtime. The procedure takes only a few minutes to perform, and patients can resume exercise the next day. The procedure is well tolerated as I combine a local anaesthetic together with the filler.

With increasing research and development we will be seeing a newer generation of HA fillers in 2022 that will last beyond months to years. In the context of scar revision, fillers remain at the forefront of the procedures I conduct on a daily basis.

The newest product introduced in 2022 is a unique heat treated, low & high molecular weight Hyaluronic Acid molecule with unique properties. This product tightens skin, induces  your own immune system to generate collagen, fat & connective tissue. It has unique tissue integration with virtually no downtime. Best of all, it is cost effective. Treatment starts at only $850 per session (performed by my head nurses). Most patients will require between 2-4 sessions. Is it as good as multi-layer subcision & correction there after with dermal fillers? No, but is it one tenth the price of surgical intervention. More on Profhilo.

In 2023-2024 we have newer injectables that have been TGA approved, this includes PDLLA fillers & polynucleotide DNA derived products, namely Rejuran S. The latter is a highly effective treatment for shallow acne scars. 2-4 sessions are required. I often combine this post laser as part of a recovery package for skin, however it can also be used as a stand alone treatment.

This new injectable is excellent for atrophic acne scars.

Fillers are not a substitute for my other procedures such as laser ablation, fractional lasers, subcision, surgery & TCA CROSS, however this technique adds another avenue for scar revision for suitable candidates. Fillers provide instant results with no downtime.

Atrophic scars can be treated cost effectively. New injectables cost $850 per session (performed by nurses).
