One ​​treatment area is larger than the other

The skin on the face is considerably larger than the opposite side, which is often described in some manufacturers' instructions or user manuals as "use one hand" and will certainly prove inconvenient for many.
The facial treatment requires a counterpole, since the facial electrode represents only one pole. For this reason, a second electrode is needed to enable the current flow. This second electrode can be applied to a foot (for reasons of convenience) or alternatively a hand.

However, the skin of the face is a much larger area than the hand that is used as the opposite pole. This means that the palm has a higher current density than the face, which might lead to problems with iontophoresis.

Example: a palm is approximately 50% smaller than the face. During the facial treatment, the current density on the palm is therefore twice the density on the face!

TIPS:

Beware of over-therapy. Since the hand is also being treated, it will usually become drier during a successful facial treatment. You can alternate between hands or feet to distribute the effect evenly. You might go even further with a special y-connector, which enables you to use both hands or feet as an opposite pole.

Iontophoresis for the head and forehead: it all depends on the affected areas!

Many users sweat more heavily on the head than the face, or they suffer from uncontrollable sweat in several areas at once. This treatment requires a little creativity when applying the electrodes.

If only a small area of the face is affected by sweat, you can moisten exactly the affected area on the face mask.

If you only want to treat your forehead, there is a better and cheaper possibility!

Important: It is not recommended arranging the electrodes in such a way that they conduct the electricity through the brain in a direct line. Brain is - after all - still needed.

If you are a little unsure about the treatment, your doctor will help you conduct the treatment under medical supervision.

If you wish to treat your entire scalp - the area that is usually covered by hair - it is possible to use small, flexible silicone electrodes in sponge pockets. These are then placed under a hat or cap, thus securing them in place. Bring the positive pole to the cap.

Alternatively, and perhaps better, place the silicone electrodes on the highest point of an undyed cotton cap and simply sew it on. Then moisten the cap in the sweaty areas.

This also works with smaller metal electrodes, since the "bulb" is relatively flat on the crown or scalp.

If any hair is present in these areas, it must be wet to allow the flow of the current through the hair into the scalp.

Now we need also a counter-pole, in this case the negative pole, since the positive pole is already present in the scalp area. What this might look like was already described above in the section "Uneven Current Distribution and Current Density in Iontophoresis".

If only a part of your scalp is affected by sweat, place one electrode with a distance of 3 cm to the hairline. Then place the counter electrode at the upper back of the head, with a distance of 10 cm to the first electrode. The electrodes should be placed horizontally, with the long electrode side running parallel to your forehead.

This treatment is conducted without a counter-pole electrode, since the current passes from one scalp electrode to the other. Leave a gap of 3 cm between the sponges. If only the upper part of the head is affected by sweat, apply the electrodes along each side of your middle parting. Leave a gap of 1.5 cm between the middle parting and the electrodes. The long electrode side should face the middle parting. In any case, the temples must be left out.

If both the face and the scalp are affected by sweat, you should first conduct a simple facial treatment and see whether it has an effect on the scalp as well. In quite a few cases, the sweating of the scalp subsides as a side effect of the facial treatment.

If the affected areas remain, a mixed treatment with a suitably cut terry cloth is a possibility. Moisten the cloth and place (or sew) it under the sponge cloth of the face mask.

If only a small part of the head is affected by sweat, such as the upper lip, you should have a look at our electrode position for small areas.

Conclusion: unfortunately, no matter how well iontophoresis works, you cannot treat all areas with equal ease. Some spots are difficult to treat. You should always pay attention to the direction of the current, especially when treating the head! It is absolutely not recommended placing the electrodes in such a way that the current is conducted directly through the brain. If you are a little unsure about the treatment, your doctor will help you conduct the treatment under medical supervision.
