INFINI RF Microneedling

INFINI RF radiofrequency microneedling is the next step beyond CO2 Fractional lasers. This system delivers controlled radiofrequency energy to break down acne scars that lie deep under your skin, whist sparing the top layers of the skin. INFINI is best suited for atrophic and rolling acne scars as well as pore size reduction. Results following INFINI RF are better than Fraxel laser, with a quicker recovery time.

Facts on INFINI: Breakthrough technology for acne scars

INFINI is the latest generation fractional radiofrequency device

Unlike other skin needling systems this microneedling device has insulated needles that can be adjusted to delivery scar breaking energy
Depth of delivery can be tailored according to the level of the scars
Atrophic and tethered scars may require up to 3.5 mm depth of penetration, whilst reduction of pore size can be achieved with only 1.25 mm
RF or radiofrequency is not laser, and hence will not affect the upper layers of skin
RF energy is concentrated deep in the dermal layer of skin- where scars lie
Downtime following RF is only 2-4 days, far quicker recovery than Fraxel or fractional lasers
It is the insulation of microneedles that gives INFINI the point of difference
Acne scars in all skin colours can be treated with insulated INFINI RF


Why is INFINI unique and how does it differ from laser treatment?

INFIINI represent the culmination of many years of development in the development of RF or radiofrequency. RF uses controlled heating through electrodes.  This delivers energy to the deeper layers of the skin- sparing the upper layers. This translates to better acne scar remodeling than laser itself.

The marked difference between Infini and other RF microneedling is the insulation of needles. This targets scars that lie deep in the skin. Dr Davin Lim.

What types of acne scars are best suited to INFINI RF microneedling?

Not all acne scars are suitable for INFINI RF microneedling. Atrophic and tethered scars do best with INFINI RF.

Ice pick scars do best with surgical punch excision or TCA CROSS. Box scar scars do best with laser resurfacing, and markedly atrophic scars are best treated with dermal fillers.

How does INFINI treat acne scars, and why is it better than fractional laser?

INFINI treats acne scars through a process called MFR or micro needling fractional radiofrequency. This system uses fine needles to puncture the skin and deliver heat to beak down scars that lie deep under your skin. Remember, acne scars lie UNDER your skin, and the aim of treatment is to spare the upper layers of skin (epidermis) and target collagen 1-3.4 mm under the surface.

Fractional (and fully ablative lasers) all work by firstly treating the upper layers before delivering heat to the acne scars. This results in prolonged healing times and redness following laser therapy. INFINI microneedling does not treat the upper layers, and concentrates the energy where acne scars lie.

Remember, not all acne scars are suitable for INFINI RF treatment, and some scars such as box-car scars respond best to fully ablative lasers. INFINI RF is best for atrophic, mixed and rolling acne scars.


How long will it take to heal from INFIINI RF?

2-4 days, depending on treatment levels. Healing times following INFINI are much quicker than with laser therapy as the upper epidermal layers are spared.


Following RF Microneedling with INFINI expect-

First 24 hours- swelling
Next 24-48 hours- swelling decreases
Next 48-72 hours – skin returns back to normal.

If treatment density is high, your Specialist will inform you of the expected healing times- namely up to 4 days. This is especially prevalent if layered passes are performed. Eg. Scars and pores are treated at the same time.


Is INFINI treatment painful?


There is a level of discomfort during INFINI treatment, depending on the settings and passes.

We minimize discomfort by-

The use of 23/7 Lidocaine cream
The use of nerve blocks
The use of ‘Laughing Gas’
Sedation if extensive areas of acne scars are treated

Overall this is a well-tolerated procedure as we ensure patient comfort levels.

What is involved with the INFINI RF treatment?

The very first step is to see if INFINI is the correct treatment for you. Assessing your acne scars is the very first step in scar management. Remember, not all scars are suited to INFINI RF

How many treatments will I need to see an improvement in my scars?

As with all fractional devices, you will require between 2-4 sessions for optimal outcomes. You will notice an improvement with just one treatment.

As a guide- atrophic and rolling acne scars 3-4 sessions.

Reduction in pore sizing 2 treatments.



4 sessions of INFINI, each session spaced 4-6 weeks apartCan INFINI be used on all skin types and Ethnic colours?


Yes. Unlike laser, INFINI spares the upper layers of skin and treats the lower dermal layers. This means sides effects such as skin colour changes are exceeding rare following INFINI RF.

3 sessions of INFINI RF


How much do INFINI treatments cost?

Standard area - $1590-1790 (acne scars)
INFINI PRP- From $2500

Does Medicare cover INFINI microneedling radiofrequency?

NO. RF or RadioFrequency is not covered under Medicare or Private Health Insurance.

An alternative to INFINI is fully ablative laser resurfacing. This procedure is partially covered under Medicare.


Specialist viewpoint on INFINI RF for acne scars

By Dr Davin S. Lim

Laser, Surgical and Aesthetic Dermatologist

INFINI from Lutronic represents the pinnacle of RF treatments. Skin needling first started off with DermaRollers nearly two decades ago, followed by stamping procedures such as the Dermapen. This was followed by radiofrequency with non-invasive devices such as sublative eMatrix- excellent for mild atrophic scars and early acne scars. Invasive microneedling was subsequently invented, however it is the insulation of the needles and sequential delivery system of INFINI that makes this a game changer.

This device spares the upper layers of skin, and delivers its energy deep into the dermal layers. The adjustability of needles from 0.25 to 3.5mm makes this an extremely versatile device to treat enlarged pores, atrophic scars and tethered scars. This device is colour blind- hence it can be used on acne scars in patients of all ethnicities. This is one of my favourite devices for acne scars, and has, in my practice replaced Fraxel lasers- INFINI is far more effective. Hands down!
