What is the main difference between direct and indirect application of high-frequency current during a facial?
a.Direct produces no ozone; indirect produces only ozone
b.Direct places the electrode on the client's skin for a germicidal effect; indirect has the client hold the electrode while the practitioner massages the skin for a stimulating effect
c.Direct and indirect are the same technique with different names
d.Direct must be performed only with neon (red) electrodes; indirect requires argon (violet)
Explanation
In DIRECT high-frequency, the electrode is glided over the client's skin and produces small amounts of ozone with an antibacterial/drying effect, helpful on oily and acneic skin. In INDIRECT, the client holds the electrode while the esthetician massages the face with hands, producing a gentle stimulating/toning effect.
