Infini RF aka ‘Fractional Microneedling RF’ vs. Fractional CO2 Laser Treatment

As technologies are rapidly advancing, we are blessed with many more choices when it comes to treating difficult skin conditions such as:

Amongst many different treatment modalities, doctor-performed Fractional Microneedling RF and fractional ablative laser are quickly gaining popularity. While both treatments demonstrate excellent results, they are different in terms of downtime, the number of sessions required and skin suitability.

What is Fractional CO2 Laser Treatment?

Fractional CO2 laser treatment uses ablative beams to penetrate through the epidermis in order to reach the dermis. This process creates microcolumns through the different skin layers and is associated with risks of epidermal pigmentation. On the other hand, microneedling RF uses insulated (usually gold-plated) needles which are inserted into different dermal depths. Insulation at epidermal level markedly reduces risks of pigmentation and therefore microneedling RF infini laser treatment is considered more suitable and safer for people with darker skin tones (Fitzpatrick 4-6) who are more prone to develop pigmentation from traumatic events, such as a cosmetic procedure.

What is Infini Laser Treatment (Fractional Microneedling RF)?

Fractional Microneedling RF, in particular Infini RF laser treatment, releases a large quantity of high intensity radiofrequency energy in a single session compare to Fractional Co2 laser. Insulated gold microneedles are used for skin tightening whilst increasing elasticity and collagen production, making the effects comparable to several sessions of a fractional CO2 laser treatment.

Not only does Fractional Microneedling RF help with skin tightening and 3D volumization. It can be used to treat the following concerns on the face and body such as:

In comparison to the fractional CO2 laser typically covers 4-5% of the treated skin surface area in a single setting in order to control effects from heat-induced collateral skin damage. Because there is less heat generated from Fractional Microneedling RF, in a single session, larger skin areas can be treated safely. Both treatments are associated with an average downtime of 5-7 days where swelling, redness and scabbing can be expected but the side effects are usually more pronounced with a CO2 laser. Therefore, the number of sessions one can commit to is usually taken into consideration when deciding between the two technologies.

Fractional CO2 and Infini RF Laser Treatment Similarities & Differences

The table below summarises the similarities and differences between the two most popular treatment modalities:

Fractional microneedling RF

Fractional CO2 laser


Indications: acne scarring, stretch marks, uneven skin texture, pigmentation (excluding melasma), skin rejuvenation, female intimate rejuvenation.

Procedure takes on average an hour.

Downtime is averagely 5-7 days following a single session.

Swelling, redness and scabbing are expected during the downtime.

Differences/choosing between the two

Suitable for all skin types.

Caution in darker skin types. Increased risks of pigmentation and redness.

Typically, 1-3 sessions required for the face.

Typically, 3 or more sessions required for the face.



Both infini RF laser treatment and fractional CO2 laser treatment modalities require a period of downtime and potential risks. It is important to have a consultation with a highly qualified and experienced doctor before commencing on treatments. The doctor will usually advise you on which treatment modality is more suitable, how many sessions may be needed and the potential risks.
