Can a genioplasty "ruin" a lip lift? Which surgery to do first?

I want to get both a liplift and a genioplasty for a weak but long chin. These procedures would not be done by the same doctor. I am wondering which to do first, and how long to wait between them (close together is more convenient). If I do the lip lift first, can the swelling from the genioplasty affect the lip lift? If I do the genioplasty first, will the length of my current philtrum affect the decision of how much to change my chin vertically?
