Rope like burn on neck from smart lipo chin 5 days post op, is it bruise or burn? (photos)

Based on your picture, it looks like more or less typical bruising from that procedure.  Keep close follow-up with your surgeon to guide you through the process.Good luck and take care,Dr. Howell

Thank you for your picture. This looks most consistent with bruising. This should resolve itself in 7 to 10 days. If this is not resolving to your satisfaction please make sure you visit this with your plastic surgeon

You look like you have bruising and swelling post treatment and should be evaluated for a seroma or hematoma.  My patients are not typically that swollen or bruised.  Best, Dr. Emer.
