Hello Interloper!

Careful discussions regarding your reasons for wanting this treatment, in lieu of other treatment options available, are very important before you begin the treatment. You must also make sure that this treatment can deliver what you want and how you would like to look afterwards. Your practitioner should be able to answer all these questions.
A medical history should also be taken to make sure that there are no reasons why you shouldn’t undertake treatment. You may be asked to sign a consent form which means that you have understood the potential benefits and risks associated with the procedure.
Photographs may also be taken by the practitioner for a "before and after" comparison at a later date.
This information refers to what to expect from a Focused Cold Therapy™ treatment with the Iovera® device.
Treatment sessions are short, taking around 15 minutes for one treatment.
The practitioner will begin by thoroughly cleansing the face. A TENS (Transcutaneous Electrical Nerve Stimulation) machine, similar to those used for back pain relief etc. will be used to actively map out the facial nerves, on application of the TENS device, the nerves in the face twitch which allows correct location. The application points for treatment can then be marked on the face.
Local anaesthetic will then be injected into the skin to numb the area where the device will be applied and then the treatment can begin.
The Iovera device has closed-tip needles at the end of the hand piece, within a single person use ‘Smart Tip’, which are inserted into the skin at the marked application points in the path of the nerve. To deactivate the nerve by chilling it, liquid nitrogen is passed into these needles when the hand piece is turned on (it doesn’t go into the skin as the needles are closed-tipped). At the needle tip, the liquid nitrogen turns into a gaseous form, nitrous oxide which draws in heat from the surrounding skin, creating a very precise zone of cold. Each cycle of application lasts 60 seconds.
Those treated are said to experience the feeling of pressure at the injection site rather than cold, although some do report that it is a tolerable pain. Once the procedure is over, the practitioner may offer topical cream to soothe any redness around the sites of the injections and you will be free to go about the rest of your day.
