Cellulite has been treated effectively by Cellfina and ThermiTight leaving a minimum of one year duration of effectiveness with Cellfina and more with ThermiTight (as the latter has been on the market longer).After Cellfina, or any invasive procedure (Cellfina can be considered minimally invasive) complications are of low risk, but exist. Infection, although rare, if occurs, may only happen more than a week after the procedure, so you should be willing to return to the treating physician for follow-up appointments. That is the concern when doing an elective cosmetic treatment not in your home town. Bruising and swelling can last for more than two weeks but doesn't mean that you can't fly a couple of days after the procedure. Swelling might be more dramatic after returning home because of the flight. That should diminish over several days. If you are wearing a compression garment, it's important, that it not be too tight at the seams, especially in flight when swelling can occur.Every patient needs to ask their doctors who will be performing their procedure this type of question.The information provided in Dr. Shelton's answer is for educational purposes only and is not intended to constitute medical advice.
