WHY DOES OUR SKIN LOSE ELASTICITY AND START TO SAG?
Our skin is tightened by a structure of collagen fibres in the dermis in a network of skin cells, fibres and blood capillaries. Below in the hypo-dermis or subcutaneous layer there is supporting fat tissue with strong and elastic collagen fibres, and the circulatory system.
As we age the collagen fibres break down and become less structured and elastic, and our repair and replacement of these becomes less efficient. External factors such as UV exposure and lifestyle can make this worse. This results in wrinkles and the changes in the deeper tissue lead to sagging often known as skin laxity.
In body areas, changes in and around fat cells in the hypodermis, where the supporting collagen fibres and circulatory system become impaired, lead to them becoming less compact and structured causing a raised and dimpled appearance of the skin, a problem known as cellulite.
