Is It Ok to Take Compression Garment off for a Couple Hours a Few Days After Chin Lipo?

This is a gamble and one you have to be willing to take consequences for.  Perhaps nothing negative will occur, but there is no way to know.  Thank you for your questions and good luck.

You should consult with your plastic surgeon regarding this question, but generally it is fine to have the chin garment off for a few hours if needed.  The garment helps to some degree in molding the final contour as well as controlling swelling. A few hours should  not significantly affect your final outcome.

I some times think that surgeons do not understand the purpose of things.  After 24 hours, the likelihood of developing a bruise from the lower face liposuction has passed.  The only purpose of the face bra, is to provide support so you don't jiggle so much.  Oh it also reminds you not to over do things after surgery.  Beyond that, it really does nothing.  It has no ultimately bearing on how you heal.  What should you do here?  Well it sounds like your doctor wants you to wear it.  You will have to decide for yourself if that advice is sound or not.
