Anyone Tried OxyLight High Frequency Facial?

Hello,

Looking for some advice. I am thinking about buying an OxyLight facial tool
for my acne - see: http://www.jellenproducts.com. It is a high frequency
device that is supposed to be excellent and is used in a lot of spas.

My friend purchased one a few months ago and loves it but my acne is pretty
severe so I am not certain it will do the job. I currently use the Proactiv
System but it is not as effective as it used to be. Maybe my skin is
getting too used to it?

Before I buy the OxyLight I would appreciate any and all comments on its
effectiveness, particularly for severe acne.

Thanks!

Heidi
