How much does real medical microdermabrasion help to reduce enlarged pores?

Can you answer plushpenguin’s question about Anti-Aging?:

What about microdermabrasion combined with an acid peel? How much of a change in my pores could I expect after one treatment? How much pain or “down time” is there after treatment? Have any of you gotten this done for enlarged pores and had good results? (remember, at home mdb is not the same thing) Thanks :)
