I can get a facial at my dermatologist's office for about $20 Canadian but it's only for about 20 minutes. Or, I can go to a salon and pay between $40-75 CDN for a facial of anywhere between 1-2 hours. The thing with the salon facials is that they usually use lots of muds, creams, and exfoliants on your face as well as they will do an extraction. Personally I'd rather just get the extraction (at my derms office) but the stuff that the salons use make your face look and feel clean.
Here's some stuff on microdermabrasion:

Microdermabrasion is a non-invasive and non-surgical procedure that sprays a stream of fine crystals directly on the skin. This crystal spray removes the surface layers leaving a smooth, fresh rejuvenated skin surface.
What conditions may be treated with microdermabrasion?
The following conditions may be treated with this technique:
Sun Damaged Skin
Acne Prone Skin
How many procedure are needed?
The average patient requires between 5-9 treatments, spaced one week apart.
Are there any side effects?
The procedure is almost pain-free and leaves the skin with little or no redness. Patients are usually able to return to the home or office immediately after the procedure.
If you do a search within the web you'll probably find some good FAQ's and other info about this procedure.
