Can I get fillers at 8pm and take a 10 hour flight the next day at 4pm?

There are no contraindications to flying after filler injections so yes you can fly a few hours after filler injections.

I would not see any problem with having fillers in your mid face a day before flying.  The flight should not affect your filler results but it is possible that you could have some temporary bruising and/or swelling as a result of the filler procedure.  

As long as the filler treatment goes well without any significant complication (which would be extremely rare to have) then there is no reason to not travel as planned. The typical mild bruising and swelling that could occur should not interfere with any activity including flying.  There also should be no worries as far as altitude changes, etc.Thank you.

There would be no issue in having fillers (or Botox), followed by any sort of airplane travel even immediately after the treatment.

There is no contraindication to flying after uncomplicated Botox/Dysport or filler treatment. Have a safe trip!

There is no contraindication in having fillers done and flying either the same day or the next day.  If you have Botox you just want to remain upright for at least the first few hours.  Best, Dr. Green

Typically speaking, there shouldn't be any problems with you receiving fillers and then flying. Good luck from New York City
