Sagging neck skin describes the wrinkles and loose skin that appear on the neck as a natural result of ageing. This process begins when the skin loses elasticity due to reduced collagen production, a decline that occurs gradually from the age of 20, with around 1% lost annually. This decrease makes the skin less capable of maintaining its firmness, leading to sagging neck skin and visible wrinkles. Seeking effective treatments for wrinkly skin can significantly improve texture and restore a youthful appearance.
