Dr. Baumann's most recent article on Yahoo is well worth a read!

I find it interesting that Dr. B says "Don't waste your money on professional microdermabrasion." I'll bet a lot of derms would be irritated by that recommendation! I've had several professional microdermabrasion treatments over the years and been very disappointed every time. I much prefer the at-home microdermabrasion creams and have found that they work better.

edit: Have a read of the user comments too! Dr. B. has p***ed off a few aestheticians by the look of it!
