How soon after rhinoplasty can I have a microderm done?

I am about 8 weeks post rhino/septo and am in DESPERATE need of microdermabrasion for my face. My skin has been completely dry and awful since the surgery. (A small price to pay for a new nose. But still, I've had all I can take). The person doing it knows I have had surgery and would of course be careful of my nose, but I don't want her to have to avoid it as the skin on my nose is what needs it most. Would this potentially affect my rhinoplasty results?
