One of the hallmark signs of ageing skin is a loss of skin elasticity and laxity which presents to many as “sagging skin”.
With age, the skin itself changes with a loss of collagen and support as well as a loss of elastin. Elastin provides the skin with the ability to stretch and snap back into position. When elastin is lost the skin becomes loose and slack and is unable to maintain its structure and position.
With a loss of healthy collagen and a reduction in its production results in a loss of skin strength and thickness. As a result the skin presents as thinner and less firm skin.
Combined with the actual skin changes, the physical appearance of sagging skin is also due to changes which happen below the level of the skin becoming more evident with age.
A loss of supportive structures beneath the skin results in less support. Atrophy of the fat pads, bone loss and resorption as well as cartilage loss all contribute to loss of the facial structure. The skin therefore loses its platform of support resulting in a sagging appearance.
