Could anyone help me on Microdermabrasion,
I am doing beauty therapy at college and I'm doing a project, part of it on Microdermabrasion...

Does anyone know what the types and effects of the electrical charges used in the treatment?

And also..

What are the effects of it on the systems:

Nervous
Circulatory
Lymphatic
Muscular
Skin

I can't find anything on these questions!

Thanks if anyone can help me it would be much appreciated
