WHAT ARE THE CAUSES ?
Skin laxity and bone resorption that set in with age are both responsible for the loss of firmness of the face and the appearance of heaviness in the lower face commonly called "jowls". This contributes to the loss of firmness of the skin of the neck.
We are all born with different genes. The genetic background that our parents passed on to us may be responsible for the premature loss of neck firmness in some people.
Sun exposure, smoking and environmental pollution, especially in large cities, can play a role in the premature loss of neck firmness.
A significant and rapid loss of weight can be responsible for a decrease of the face's firmness. This process contributes to the loss of firmness of the skin of the neck as well.
