High Frequency gass...

[p0kkelpen$ie]

This might be a very stupid question...but why do certain HF electrodes contain different gasses? Mercury/neon/argon...Better conductivity? Cheaper?

...what is your opinion on oxygenating cream? Would it be wise to use this on a alipidic skin? Ozone is formed and due to the fact that this is drying,healing and anti-bacteria, why use it on an already lipid dry skin? Here in South Africa we decided not to use the oxygenating cream but as soon as our international examiners comes and assesses our students, they want us to use the O2 cream...

Any internationl opinions??

Haven't a clue i think they are usually argon though in the machines we would use.
Ruth might know whether one may be dearer than another to produce and whether the outcomes are the same.
