Should I choose Pulsed or Direct current?
Well, that really depends on the user.
The decision to use pulsed current iontophoresis over direct current is normally based on skin compatibility during iontophoresis treatments. If a patient is performing iontophoresis treatments on for example the hands to treat Palmer Hyperhidrosis and is experiencing discomfort with direct current, then switching to pulsed current would make treatments much more comfortable and therefore ultimately more effective. You will not achieve results if you cannot tolerate the current.
It’s important to note that not all patients will find direct current iontophoresis uncomfortable. Therefore not everyone will need to order a pulsed current machine. The feet, unless you have secondary skin conditions, are more often than not, fine with direct current treatments. There are some areas of the body that in our experience often encounter discomfort. The hands and underarms often require more sensitive pulsed current treatments and this is even more so for torso and face.
Benefits of pulsed current Iontophoresis
There is no down side to pulsed current treatments other than some loss in efficiency. If you were to perform a treatment for 20 minutes in direct current, then you would receive 20 minutes of ‘dosage.’ This is 100% efficient but direct current particularly at higher powers can be uncomfortable. Switching to pulsed current will offer a much milder experience. Pulsed current is less efficient due to the fact that the machine is pulsing on and off.
Standard pulsed current machines only offer P50 which means the machine is on and off for equal amounts – 50% on, 50% off. This means that over the course of your 20 minutes tap water iontophoresis treatment, you are actually only receiving dosage for half the treatment time or 10 minutes. This may mean that you need to perform more sessions to reach the same result.
Hidrex advanced features
Unique to the Hidrex PSP1000 is a feature where you can adjust the on off pulse cycle in 10% increments (P60, P70, P80 etc). This greatly increases efficiency buy as much as 80% in the P90 setting. P90 applies power 90% of the time with only a 10% break in power so over the same 20 minute session you will receive 18 minutes of dosage but it will be milder than direct current. This setting is particularly useful for younger users and patients treating axillae Hyperhidrosis or underarm sweating.
