2 Weeks post op Facelift. Will the bright pink, raised scar under my chin go away? (photos)

All incision take time to heal.  Scars go through an evolution for a year after surgery and sometimes longer.  At 2 weeks it is too early to tell but redness and a raised scar can be normal.  Scar management after facelift surgery is one of the reasons follow up visits are so important. I will occasionally inject a steroid into the scar to help flatten it.  I generally do not do this until a month after surgery. Massage can helps as well. See your surgeon if you have any concerns. He/She performed the surgery and should guide you through the healing process. 

Your scar looks normal for the first few weeks following your procedure. See the below link for detailed information on how to achieve the least visible scar.

If designed and closed meticulously, the scar underneath chin will typically feel firm and a little "thick" during the initial weeks after the procedure but will dramatically soften and flatten very quickly.  Sometimes an injection of Kenalog will hasten the flattening, but typically your body's own healing process will do all that is needed.I hope this helps.
