As the skin ages, a loss in collagen production causes the skin to no longer be elastic. The skin will then begin to sag and have an aged appearance. This occurs in the neck area where skin loses elasticity much quicker causing deep striation patterns in the neck. To improve the skin’s elasticity and texture, it is important to treat all layers of tissue in the neck. This includes the outer skin layer, the subcutaneous connective tissue, fat and muscle.
