I'm getting an upper bleph. Will arnica and bromelian help with bruising & swelling?

Great question, absolutely!  I usually start patients on arnica the first day post op.  Also, keeping your head elevated and icing for the first 24 hours.  Still, you need to follow your plastic surgeons recommendations for post op recovery.  These are just suggestions that may help.  Good luck

Blinded controlled studies show benefit from these medications with respect to bruising and swelling with little side effects.  If you have liver disease or heart disease you will need to discuss with your surgeon prior to use.
