Is my neck lift infected? I had an extended neck lift 5 days ago. (Photos)

Your necklift incisional areas seem to be healing normally and don't look infected.  I would recommend that you follow up with your surgeon to discuss your concerns. 

Some redness, bruising and swelling is normal after any operation which does not mean infection.  Increasing swelling, drainage and fever can indicate an infection.  At 5 days post op it is difficult to determine which, but you should be checking with your surgeon.
