A threadlift is not the same as a Lyfestyle lift. A threadlift is a procedure that uses long sutures with little dissolvable stops on them that are placed into small incisions in the hairline. It works by lifting the sagging of the cheeks, but not the jowls or neck. The Lifestyle lift is a brand name that refers to a minifacelift. An incision is made in the creases around the ear and the sagging tissues of the jawline and neck are tightened with multiple sutures, and then the excess skin is removed. It does not improve the cheeks. Both procedures can be done under local anesthesia. If you are considering either procedure make sure to consult a board certified facial plastic or plastic surgeon to see which procedure you are a better candiate for.
Thread lifts (contour lift) use permanent sutures that are placed under the skin. The names change based on marketing but the anatomical principle is the same. The results are temporary because they do not access the prime issue with ageing: Descent of the structures that contain muscles (fascia). In a facelift, the main fascial system is elevated and sutured to another fascial system which provides longer-lasting results because this is the strength layer. While people are a bit anxious about getting a facelift, it has lasted for more than 30 years because is addresses the anatomy of ageing not the marketing hype of the time. In the thread lift only the skin is elevated and as we all know, skin is elastic and over time sags. The procedure can cost anywhere from $3-$6000 depending on your geographic locale. As I mentioned, the sutures are permanent and if placed to superficial can cause irritation to the skin. Good technique is always critical to the success of any surgical procedure. See a board certified plastic surgeon to assess what is best for you.
