As we age, the skin on the neck can lose elasticity, leading to sagging, wrinkles, and unwanted fat deposits. A neck lift is highly effective for tightening the skin, removing excess fat, and smoothing wrinkles, giving you a more youthful and defined appearance. A neck lift is a surgical procedure to improve the signs of ageing in the neck and jawline. Technically known as a lower rhytidectomy, this surgery is performed to treat excess fat and skin laxity in the lower face that causes jowls, excess fat under the chin, vertical bands in the neck, and loose neck skin.
