Do I need to use/do microdermabrasion?

I'm trying to develop a skin care regimen for my face. So far I'm doing a cleanser, scrub every other day, and then moisturizer while doing a facial once or twice a week. I plan on adding a toner to my daily regimen as soon as I buy one. My question is do I need to do micodermabrasion as well? I was thinking the easy Olay kit or whatever that's in the bottle or something else easy like that. Also, if it would be a good idea to use one how do I add it to my regimen?
