How tight does my Ace bandage need to be after face/neck lift?

There are multiple ways to prevent swelling and allow a rapid recovery.  Tight bandages are typically not recommended for long periods of time as they may impair the blood supply.  In my practice, patients wear a loose elastic garment for the first 24 hours which is switched to a light face and neck bra for the first few days and adjusted to comfort.  If pain is out of the ordinary, speak with your surgeon to ensure appropriate healing.

Hi do you still have drains in? If so then the bandage does not need to be so tight. The bandage should feel snug and firm and not tight to the point that it causes pain. Some lines and indentation is expected due to swelling. The garment may be small if it is still tight on the loose setting.

I recommend contacting your surgeon ASAP.  Garments should not be so tight that it is still causing you pain and discomfort.  Your surgeon should be able to treat you accordingly.  Best of luck.
