Seroma, edema on neck under my chin? What is this? (Photo)

Thank you for your question.  This could be a serum, scar tissue, or untreated platysmal bands.  I would recommend speaking to your plastic surgeon about your concerns, and they can examine the area and come up with a treatment plan.  All the best,

The only way to know for sure what is causing these wrinkles is with an in-person examination by a board certified plastic surgeon. If they are unrepaired platysmal muscle bands, then they would move and tighten as you animate your neck. If they do not tense or change with neck muscle animation, then it is likely excess skin. In my opinion this is unlikely to get any better with time. Search for board certified plastic surgeons in your area to get the discussion started.Best of luck!Dr. SubbioBoard-Certified Plastic SurgeonNewtown Square/Philadelphia, PA
