Should I be concerned about hardness after my facelift?

Your description can be very normal after a face lift.  These are areas of inflammation where increased blood flow and swelling can make the area more firm than the surrounding tissue.  This will almost definitely subside in the coming weeks.  As I've said many times- patience is the most difficult part of surgery!

     Hardness as well as lumps are normal at 12 days following a face and neck lift.  The hardness may take 3 to 6 months to soften, but most of the swelling is gone by 2 to 6 weeks, depending upon what was done and how it was done.

12 days is still very soon after your surgery, and you will be experiencing swelling and tightness at this time. It can take some time before the side effects resolve, and it is important to be patient during the healing process. In the meantime, I would recommend speaking with your surgeon regarding any concerns, and seeing him or her for a follow-up if necessary. Thank you, and best of luck with the remainder of your recovery.
