All surgical incisions leave scars, and fortunately are rarely a problem. In addition, your plastic surgeon tailors the neck lift or face lift to address areas that are appropriate for you and your personal goals.
Neck lift incisions are placed in strategic locations to hide & camouflage the final results, to avoid visible scarring. All facial incisions for plastic surgery slowly improve and mature with time. Initially, face lift incisions will appear red and swollen. The incisions gradually become less noticeable with good postoperative care, such as avoiding the sun & smoking. Most face or neck lift healing occurs within the first couple months, but the incisions continue to improve up to a year. The facial incisions will never completely disappear if one looks closely, but should be less visible.
Speak to your neck lift plastic surgeon to help alleviate any concerns. Best of luck.
