Still heavy puckering behind ears 3 weeks after face and neck lift (Photo)

You appear to have undergone a short scar facelift.    With the short scar the excess skin often puckers behind the ear.  This generally resolves over a few months.  In certain cases a touch up of the post auricular scar is needed.  

It is still too soon. You may still have some swelling, which will slowly resolve over the next several weeks. I do recommend following up with your surgeon about your concerns. Microneedling can help improve scars. I hope this helps. 

Hello,
   Thank you so much for your question! It’s hard to say without your preop and postop Facial pictures but from what you posted it appears your surgeon used a short scar facelift. This approach uses a shorter scar for smaller facelifts but requires the skin to be pleated in behind the ears. It should settle with time usually several months up to a year but can be revised if you wind up unhappy with it. This is a well known shortcoming of the short scar style lifts. I do hope that helps and I hope you are happy with your facelift result otherwise. 

Sincerely 
Dr G
