facelift-how long does it look good?

[kgav]

I am about to have a extended macs facelift, however my daughter has just surprised everyone and named her wedding day, april 2010. I am now left in the position of not knowing whether to go ahead with my surgery now or wait until nearer the wedding. My problem being, will the facelift still look really good 19 months down the line or will things start to sag slightly by then? We are told it takes about 10 years off, but when do noticable signs ofageing begin to show again. Obviously I want to look my best on the big day, help !
