What is Infini microneedling RF

Radiofrequency is a nonsurgical method practitioners use to tighten skin. These devices deliver electrical energy into your skin and heat a targeted area to stimulate collagen production. Microneedling is a minimally invasive procedure that uses very small needles to cause microinjuries to your skin, which also stimulates collagen production to help repair the injuries.

Unlike microneedling alone, the combination of radiofrequency and microneedling can reach the dermis, making it effective for all skin types, minimizing the risk for hyperpigmentation in darker skin tones.

Why choose Infini microneedling RF

Most patients can see noticible improvements with only three treatments.

Compare to CO2 laser, infini does not damge the epidermis, there is minimal risk of hyperpigmentation, and patients have much less downtime, they can wear makeup the next day.

Patients can see better results with Infini compare to other microneedling RF devices, Infini can reach 3.5mm deep into skin to treat deeper acne scars, stretch marks and see more skin tightening effects.

How does it work

Practitioner will numb treatment area with a topical numbing cream from 40 to 60 minutes before the procedure.

The entire proceduure will take 30 to 45 minutes to complete. Patients will experience temporary mild bleeding, swelling and redness, usually resolves in fewer than 3 days.

A minimum of three treatments is recommended, usually space 4 to 8 weeks apart.

What does Infini microneedling RF correct?


Acne Scars

All types of scars can be treated, but particularly acne scars and Infini is safe for use on darker skin types.

Skin Tightening

Loose skin can be tightened on the face (non-surgical facelift) with the neck and jawline being most popular. Other body areas such as chest, knees abdomen, and arms can also be treated.

Stretch Mark

Infini Micro Needling RF is an excellent treatment available for stretch marks.

Enlarged Pores

When microneedling on enlarged pores, the skin, for some days looks a bit rough and the pores appear bigger because of the damage caused by the needles. After a natural wound healing response is activated, that produces new collagen, the skin looks plumped up and tightened and the enlarged pore becomes smaller.

The micro needling technology of the Infini enables the needle to be inserted at variable depths, and hence the energy can be delivered at different levels. This is important to individualise treatment as some areas of the skin are different in thickness than other areas, and also some skin conditions require deeper treatment levels than others.

The Infini can treat at a much deeper skin level than Lasers. By using microneedles, the Infini can reach up to 3.5 mm below the surface of the skin, which is why it can reach the deep dermis layer of the skin and result in collagen production and skin tightening. Lasers used in cosmetic medicine target structures in the epidermis and upper dermis of the skin and do not have much effect below about 1.5mm depth. This means lasers are best for treating the surface of the skin and are the treatment of choice for such things as removing unwanted pigment, blood vessels, hair, and tattoo ink.

The other significant advantage of radiofrequency energy is that it is ‘colour blind’ which means it doesn’t matter how dark the skin is or even if the surface is tanned at the time of treatment. In contrast, Laser energy is very colour dependent, and great care needs to be exercised when using lasers to treat darker skin types and tanned skin, because of the risk of unwanted side effects such as increased pigmentation.

The Infini uses microneedle technology primarily because by delivering Radiofrequency energy through a needle, the heating can be accurately and safely directed and localised into the dermis of the skin.

Various devices in the past have tried to apply radiofrequency energy onto the surface of the skin to heat below the surface, but results were disappointing. This is because to heat the deeper dermis to a high enough temperature to stimulate collagen is difficult without damaging the surface of the skin. Differences in skin thickness, hydration, collagen, and fat make the depth of heating unpredictable. If tissue heating doesn’t occur at the right level at the right temperature, then minimal collagen stimulation occurs, and poor results are achieved.

Trauma from the needles penetrating the skin also causes mechanical stimulation to fibroblast cells in the skin to also help in producing collagen.

The needles used with the Infini are gold plated to minimise any chance of allergy. The needles are very fine, only 200 microns (0.2mm) thick. The Infini uses a tip that has 49 tiny needles (also called pins), and they deliver the energy in what is called a fractional mode. The needles are insulated, which means that the energy is directed through the tip of the needle, and heating can be accurately targeted and controlled.

The Infini is a fractional radiofrequency machine. The idea of fractionating energy was first used in the Fraxel laser in 2005 and essentially what it means is multiple discrete points of skin are treated surrounded by unaffected skin. Fractionated treatment assists wound repair and result in faster skin healing, less discomfort, and greater safety for the patient.

No, everyone cannot have Infini, but in practice, very few patients need to be excluded. Patients with cardiac pacemakers or implanted defibrillators should not have any electric type treatments, including Infini. Patients with cochlear implants should also avoid radiofrequency treatments because of potential damage to the implant.

If there is a metal implant in the area being treated, the skin overlying the metal implant should not be treated. If someone has a known allergy to metals then caution needs to be exercised as the Infini uses metal pins; however, the needles used in the Infini are gold tipped to reduce the chance of any metal sensitivity.

Patients with acute skin disease should not have any cosmetic treatments, including Infini.

Patients who are pregnant or breastfeeding are as a general rule advised against all elective procedures, including the Infini. While there is no evidence, it is not safe, there is also no evidence to prove it is entirely safe. Also, it does involve the use of quite strong topical anaesthetics, and we recommend deferring Infini treatments until after breastfeeding.

Patients with severe medical conditions such as uncontrolled diabetes, autoimmune diseases, or cancer can have Infini but will not get as good a result because of impaired skin healing. Similarly, patients who are unwell or are smokers will not tend to respond as well to Infini compared to healthy patients.

Patients on certain medications need to be more cautious before having Infini treatments such as patients on blood thinners who might bruise more easily and drugs that cause photosensitivity that might have a more severe reaction after treatment.

The Infini needles are virtually painless as they are inserted into the skin because they are so fine and are inserted very fast. Also, the 49 microneedles in the tip of the Infini handpiece do not all punch into the skin at the same time but are inserted serially in rows. However, when the radiofrequency energy is delivered through the needles, it can be felt and cause discomfort from the heating below the surface of the skin. Hence for an Infini treatment, a topical anaesthetic is applied before treatment. When the topical anaesthetic is used, most people rate the procedure as only 4 out of 10 in terms of pain.

If someone has metal pins, implants, or artificial joints in other parts of their body, they can experience a tingling sensation in those areas during an Infini treatment. This is caused by the electric current used in Radiofrequency energy but is not painful.

Topical anaesthetic cream is applied 60 minutes before treatment. During treatment, a cooling machine (such as a Zimmer cooler) can be used but is not essential as the insulated needles used with the INFINI avoid heat damage to the surface of the skin. Treatment of a full face takes about 45 minutes and face and neck about 60 minutes.

Each area is typically treated at different depths with 2 passes for each depth. There can be some pinpoint bleeding when the microneedles penetrate the skin and occasional bruising. After treatment, a cold pack is used, and then a soothing cream applied. Recovery time can be reduced by the use of a special LED light straight after treatment.

The general expectation is to have some downtime for about 48 hours after an Infini treatment. There is some initial redness and swelling after the procedure, this reduces quite quickly in the first few hours then some residual redness typically lasts for about 2 days. There is sunburn-like sensation after treatment due to the heating beneath the skin, and this also gradually dissipates over the first 48 hours.

Typically some early improvement is seen due to collagen contraction and tissue swelling then further gradual improvement continues to occur over the next few months. Full results take 4-6 months, as this is how long it takes collagen remodelling to be completed.

Most patients see improvement with only one treatment, but optimal results in facial rejuvenation, skin tightening, and Hyperhidrosis typically takes 3 treatments. It is important to remember that the Infini is fractional technology, with areas of healthy skin left surrounding the areas being treated to minimise downtime and side effects and allow for rapid healing. These areas of untreated skin are targeted in subsequent treatments. The best results with acne scarring can take 5-6 treatments.

The usual interval between INFINI treatments is 3-4 weeks, but they can be spaced further apart if necessary, and this will not adversely affect the final results. In facial rejuvenation and skin tightening, it is usually recommended to have a follow-up treatment every 12-18 months to maintain results.

The Infini is an ideal treatment to combine with lasers because it is so targeted without damaging the surface of the skin. One example is in the rejuvenation of sun-damaged skin, we can treat with the Infini to improve the elasticity and wrinkles followed with the 1927 Fraxel Laser to treat surface pigmentation.

Topical treatments can also be combined with the Infini. The micro needling creates an opening in the skin for topical products to penetrate and be more effective compared to when they are just applied to healthy skin. Products that have been used successfully include Vitamin A, Vitamin C, Hyaluronic Acid, Growth factors, and Hydroquinone.

Treatments such as anti-wrinkle injections are best not performed on the same day as Infini if they are in the same area. The heat from the radiofrequency can reduce the effectiveness of the anti-wrinkle injections and also tissue swelling after Infini treatment can potentially result in the migration of the anti-wrinkle product and unwanted side effects. Dermal fillers based on Hyaluronic Acid can also potentially be broken down more quickly if the Infini is used in the same area.
