Flying after procedures can sometimes be fine but in other situations may be problematic. The changes that occur with flying which can be of concern are changes in air pressure and very low humidity. Flying after botulinum toxin injections, vascular laser treatments, noninvasive skin tightening (Thermage or Ulthera) is not a problem. Flying after most filler injections (Restylane, Juvederm) should also not pose a problem. Flying within the frist week after surgery can be a problem at times as it may predispose to bleeding or increased swelling. Flying after skin resurfacing isn't usually a problem but be prepared to use extra moisturizer on a long trip as the air in planes is so dry.
