Side effects are not always, but very often, preventable. Tap water iontophoresis is a proven therapy that is generally very well tolerated. When used correctly, unwanted effects occur only rarely.
Side effects may sometimes occur if the skin is particularly sensitive, if a skin condition or injury already exists, or if the user experiences a pronounced sensation of electric current. However, side effects are much more commonly caused by improper use of the device or overly intense treatment.
If you use the Saalio® device correctly, most side effects can be avoided.
