How do Radiofrequency systems work?

RF is an acronym for:

RadioFrequency

Radiofrequency systems work on the principle of 'Joule heating'
  • Electrothermal damage is induced when the RF current meets resistance in the target tissue.
  • The higher the level of the current, the greater the damage.

RF in the practice of medicine

  • High frequency radiofrequency has been used in the practice of medicine for over 70 years.
  • 2002: The first device cleared by the FDA for dermatological procedures for electrocoagulation.
  • 2009: Cleared by the FDA for non-invasive treatment of wrinkles and creases.
Definition of 'Skin Tightening'
  • The FDA does not recognise ‘skin tightening’ as an indication because this term is difficult to define.
  • ‘Skin tightening’ really means a reduction in the appearance of lax skin. It does not necessarily mean that the skin shrinks or becomes more stiff.

RF for tightening the skin

How does it work?

  • Heating the dermis to a high enough temperature causes collagen coagulation.
  • Collagen coagulation results in immediate skin shrinkage and initiates the wound healing process.
  • New collagen and elastin formation takes place.
  • New collagen replaces old collagen during remodelling.
The ideal temperature in the dermis is between 55° - 68C
  • The higher the temperature:
    • the more RF energy is required.
    • this produces more visible results.
    • the more intense the degree of coagulation and the shorter the required exposure time to heat required.

The Infini RF system

Why combine RF with needles?

The benefit of micro needling is that the trauma from the needles penetrating the skin causes mechanical stimulation to fibroblast cells in the skin to also help in producing collagen

Needles
  • Uses an array of ultrasharp needles (200 microns in diameter).
  • Variable depths of skin penetration from 0.5mm to 3.5mm in 0.5mm increments.
  • Allows predictable treatment of several levels of the dermis.
  • The use of shallower depths is particularly important in thin areas of the face such as the areas below the eyes.
Power
  • Very wide power arrange available from 2.5W – 50W in 2.5W increments.
  • In clinical practice, only one power level is used and this is a a low power setting.
Exposure time
  • The exposure time determines to the extent of secondary thermal damage (via conducted heat).
  • Exposure settings are reduced to avoid secondary conducted epidermal thermal damage.
Passes
  • In most (but not all) parts of the body treated with Infini RF, 3 passes are made.
  • The first pass is set to deliver energy at the deepest level and the final pass at the most shallow level.
  • At each activation the needles enter the skin, deliver the RF energy and withdraw, leaving a discrete zone of thermal damage at the preset depth.

Infini RF treatments

Skin tightening and lifting
Skin rejuvenation
Photoaged skin
Skin laxity: neck & body
Stretch marks
Large pores
Hyperhydrosis
Acne scars
Active inflammatory acne
Excessive sebum secretion
  • Can be used in all skin types including tanned skin.
  • Minimal risk of hyperpigmentation.
  • Can treat scars of all types.
  • Very few limitations as to where the skin can be treated on the body.

Infini RF treatment is an office procedure
  • This is an office, non-surgical treatment.
  • The risk of adverse events is extremely low when performed by well trained operators.

Preparation for treatment

7 days prior to treatment

Stop taking supplements that increase bleeding/bruising such as:

  • green tea, fish oils, Evening Primrose oil, garlic, Echinacea, St John’s wort, Vitamin E, Non-steroidal drugs
  •  and aspirin (*only after discussing with your doctor)
On day of treatment
  • Before attending for treatment you can use some simple analgesia such as paracetamol but not any non-steroidal anti-inflammatory drugs such as Nurofen or Ibuprofen  (which interfere with platelet function).
  • It is best to be well hydrated, so drink plenty of water in the 4-5 hours prior to treatment.
  • After treatment, continue to drink water liberally and use simple analgesia (not non-steroidal anti-inflammatory drugs) if required.
Post treatment care instructions
  • Avoid hot showers or saunas on the day of treatment.
  • Gentle washing with warm or cold water only.
  • You may feel a burning sensation for 1-2 hours after treatment and the feeling of heat on the treated areas for several more hours. You can apply;
    • a wrapped ice pack or frozen gel pack but avoid direct contact with the skin.
  • Pinpoint bleeding is a normal skin reaction on the day of treatment;
    • Dab the area with clean cotton pads.
  • Avoid using makeup for 24hrs. If essential a mineral make up can be applied.
  • Rarely, the skin tone can become darker with crust formation from 1-2 days after treatment;
    • This is a normal process and will resolve by itself.
  • Do not forcibly scrub or remove epidermal debris;
    • Please leave them to exfoliate naturally.
    • Never use scrubbing agents or exfoliants.
  • Avoid using alcohol-based cosmetics for at least 2 weeks after treatment.
  • Use moisturising agents frequently.
  • Apply a UV-A/B sunblock with SPF of 30+ regularly and use physical sun protection (ie. hat/umbrella) when outdoors to reduce the risk of hyperpigmentation.
  • Avoid vigorous activity, alcohol consumption, exercise and sauna for at least 7 days post treatment.
  • Do not use retinoids (Fit A containing preparations) for at least 1 week before or after treatment.

Skin reaction after treatment

Immediately post treatment:

  • Redness and transient oedema.
  • Resolves spontaneously after 1-2 days.

1 day post treatment:

  • Redness and oedema begin to resolve.
  • Skin returns to a condition similar to before the treatment.

3-7 days post treatment:

  • Brighter skin tone.
  • Reduction in sebum secretion in oily skin types.

1 month post treatment:

  • Improvement in appearance of fine wrinkles and skin laxity.

1-3 months post treatment:

  • Continuous improvement in the appearance of fine wrinkles, pores, scar and skin laxity.

Frequently asked questions

How long will the treatment take?

The approximate treatment time is between 20-30 minutes, however, a local anaesthetic ointment needs to be applied for 45-60 minutes prior to commencing treatment.

How many treatments will I need?

The recommended number of sessions is 3. The minimum interval between sessions is 4 weeks. Repeat treatments may be beneficial every 6-12 months depending on the indication for treatment and whether other treatments are being applied at the same time.

How long is the downtime after the procedure?

See ‘Post treatment care instructions’ above.

Is this done in the office or hospital?

This is an office procedure that does not require admission to hospital. To reduce discomfort associated with treatment local anaesthetic cream or ointment is applied between 30-40 minutes prior to treatment.

How effective is the treatment?

Good for the indications noted above.

Individual outcomes may vary.

Is there a Medicare rebate for the treatment?

There is no Medicare rebate for the treatment.

When will I see results from the treatment?

Although some patients see results very quickly, most will recognise improvements 3-4 weeks after the first treatment. Optimal results are seen 3-6 months after the final session due to new collagen development.

How long will the results last?

The Infini is a long-term tissue rebuilding treatment. The clinical results should be long lasting like a fractional laser treatment (up to 3 years depending on the health of the skin and how the skin is looked after).

How long do I wait if I've had other treatments?

For treatments such as neuromuscular toxins and fillers you need to wait 2 weeks before having Infini treatment.

Is there any pain associated with the treatment?

The treatment is not painless but is well tolerated by the majority of patients. It is more uncomfortable on thinner skin areas of the body such as the forehead or beneath the eyes.

Can treatment take place at any time of the menstrual cycle?

The treatment can take place at any time of the menstrual cycle.

How does radiofrequency work?

See ‘How do radiofrequency systems work?’ above.
