Axillae (Underarm) Iontophoresis Treatments

We recommend that underarm treatments are performed using pulsed current as this is a far more comfortable experience. Switching to pulsed current should enable you to increase the power which will help with overall results.

It is important to remain within comfortable levels at all times.

Reddening and mild irritation and or itching for 10-20 minutes after treatment is often reported and an expected response to the electrical stimulation.

Our  top ten recommendations:

  1. Switch to pulsed P90
  2. Increase power – but remain within comfortable levels
  3. If you cannot increase power, increase time to compensate. 2 x 10 minute sessions when in pulsed current is OK
  4. Ensure pads are soaking wet with warm water.
  5. Re-soak after first 10 minutes session
  6. Ensure skin is clean and clear of any topical products (deodorants, skin creams etc)
  7. Apply moderate pressure throughout to ensure good contact with skin
  8. Reduce underarm hair if present (hair is non-conductive)
  9. Perform daily sessions until dry
  10. Moisturise AFTER treatment to soothe skin.

Machine efficiency. Which machine type is best?

The core differences between the two types of current delivery centres around the efficiency of the machine and the sensitivity of the current. Pulsed current is milder and more sensitive on the skin. Direct current is more efficient.

If you don’t have sensitive skin or secondary skin conditions (such as eczema) then you may be fine with the cheaper GS (direct current) models of machines.

PS or pulsed current gives a milder treatment sensation at higher powers but pulsed current is less efficient in terms of treatment times. For example, direct current applies power to the treatment area 100% of the time, so a 20 minutes session will provide 20 minutes of dosage.

Pulsed current power is applied in an on / off pulsing cycle which on the Idromed machine is a 50% on / 50% off ratio so power is on for half the time of direct. This means a 20 minute session gives 10 minutes of actual dosage.

The Hidrex brand offers both pulsed and direct but the Hidrex PSP1000 is both pulsed and direct in one machine so can be switched to suit the patient / treatment area. You can also adjust the pulse cycle to enhance efficiency to 90% on / 10% off. This gives the patient the benefit of near direct current efficiency and pulsed current sensitivity.

Treatments of the torso

Some general advice regarding your treatment of the torso:

We recommend setting the machine to pulsed current. There are several different ‘strengths’ of pulsed current with P90 being the strongest and P50 the mildest. P100 = direct current. Set the machine to P90.

For treatment time we suggest a minimum time of 20 minutes per day but while treating the torso you may find it easier to split into 2 x 10 minutes session so that you can re-soak the electrode sponges and re-position the pads on the torso to treat a larger area.

The voltage level is patient specific and we recommend operating at the maximum comfortable level. On your first treatment start low, say 10volts and build up to your max comfortable level.

Soak the sponge covers in warm tap water. Set up your machine then apply electrodes to the body. You can hold them in place with a towel wrapped around the body. It is best to position one pad on the front and one on the back. Do not allow electrodes to be in close contact as this will shorten the circuit and prevent you getting any real current passing through the treatment area.

Perform sessions daily until result are seen. This can take 2-3 weeks so keep up with daily sessions. Once dry, you can stop treatments and then maintain periodically before sweating returns. If you allow sweating to return you will need to start back with daily session to regain control of sweating.

Changes in power levels

It is also worth noting that as a patient dries, the amount of resistance offered by their body alters and this can be seen on the screen. All components in the circuit can affect current flow, skin wetness, skin thickness, body temperature, water temperature, water quality, patient hydration etc, etc. In basic terms, if a patient has very wet dermis, then resistance is low, currently flows easily and sometimes there is so little resistance the machine may not be able to deliver enough current to maintain a selected power level. On the other side, if resistance is too high then the machine cannot push the current through the body easily and with very high resistance the circuit will not close at all

Foot pre-set button – Hidrex PSP1000

There is no specific foot treatment setting on the machine. The top three LEDs on left hand side are memory recall points which for convenience are labelled with the most comment treatment areas hands, feet and axillae). These are simply memory storage points whereby you can set and store the preferred settings for each treatment area and can recall them for convenience. You can only switch between when the unit is in SET mode immediately after turning unit on.

A video on the pre-sets can be seen here: https://www.iontocentre.com/index.php/ic_eng_uk/support/video-support1.html

International Orders & Money Back Guarantee

Our Money Back Guarantee applies to all our customers, regardless of where you are located. It is not just a UK / EU offer.

The eight week guarantee on our Iontophoresis machines begins once the unit is delivered and not when you order so you do not need to worry that you will lose guarantee time while goods are in transit.

The only consideration international customers have to consider is the return shipping costs as these are the buyers responsibility. You may also have to consider that if you have paid import fees (Non EU customers) you will be able to claim these back from your local customs authority.

Wet or Dry skin. Does it make a difference? Hidrex PSP

The machine will still work regardless of whether the skin is dry or wet, except in exceptional cases where hands are very dry offering too much resistance and the over treatment protection system will prevent operation until the moisture levels in the skin return to safe levels for treatment to proceed. If you are still sweating at times and have only performed 3 sessions it is unlikely that the skin is too dry and over treatment is active.

 The machine ‘looks’ for upper and lower resistance levels. If the resistance is outside the expected parameters then the machine will not function for safety reasons (immersion monitoring and over treatment protection). If the dive light illuminates then the circuit is normal. When you have 20v on the display, then place your hands in water, the DIVE light should illuminate and the volts drop to 0 then rise to 20v automatically. Water quality can affect current flow so ensure the water used is not from a softened supply and warm tap water is better.

Iontophoresis machine rental service

Unfortunately a machine rental service is a prohibitively expensive service to administer so we do not currently offer it.

For hygiene reasons, each patient requires their own set of electrodes, treatment trays and towels. You would have to pay £85 for personal electrode kits, circa £60 per month rental and provide a security deposit in the region of £250 to cover the rental term.

Machines have to be re-certified at significant cost after each rental and the cost of underwriting the machines that never get returned is too high to make it viable.

For these reasons we feel machine rental is exploitative, expensive in the long term and represents very poor value for customers.

Our full money back guarantee is a far fairer method of providing equipment risk free.

Best machine for a child with Hyperhidrosis?

The best suited machine for your 7 year old daughter would be the Hidrex PSP1000. This unit is both direct and pulsed current and also uniquely benefits from having adjustable pulsed current strengths. Essentially this meand the machines power delivery can be adjusted up or down to suit each patients tolerance levels.

Direct current applies power 100% (direct current is shown on the display as P100) of the treatment time, and for normal skin types in non-sensitive areas such as the feet, this delivery method is perfect as it has the power and efficiency to give good results. The issue can be that direct current can be uncomfortable or even intolerable at moderate to high power, especially on younger users, sensitive skins or prone areas such as hands and underarms.

This is where Pulsed current comes in to its own (pulsed currents have P numbers that range from mildest P50 up to P90 the strongest pulsed setting). It basically is a mild or sensitive method of current delivery. The patient does not ‘feel’ the current in the same intensity as with direct current which allows you to operate at adequate power levels without discomfort.

P100 = 100% power, so over a 20 minute session the patients receives 20 minutes dosage.

P50 = 50% power, so over the same 20 minutes session the patient receives only 10 minutes dosage.

This can mean that overall treatment times will be longer, or the results could be less significant, however the Hidrex PSP1000 uniquely has the ability to adjust the pulsed strength in 10% increments to very near direct current efficiency.

P90 = 90% power, so over a 20 minutes session the dosage is 18 minutes but the sensation is still mild, but efficiency is vastly improved giving faster results and better responses.

Electrode cleaning and hard water

Hard water is good for iontophoresis and electrodes will discolour from first use. This is merely a cosmetic issues so nothing to worry about.

Scale can build over time and restrict current flow (increases the resistance in the circuit) and so electrodes will require periodic replacement (years not months). Clean by soaking in vinegar / water solution for 30 minutes every now and then (not too often – perhaps every 6 months or so).
