With aging, all facial elements undergo specific and stereotypal modifications.
This results in an appearance typical for a specific age group, well recognizable by others.
There is a sequence of events that take place in the aging process, which include:
● loss of forehead skin elasticity and subcutaneous fat, which, along with increased depressor muscles tonus, results in apparent skin redundancy and pronounced frown lines
● brow ptosis
● wider and deeper orbital appearance
● distortion of the superolateral upper orbital rim with excess upper eyelid skin and fat (hooding)
● distortion of the inferomedial orbital rim: protrusion and sagging of fat, muscles, and skin
● prominent nasolabial folds
● deeper and more vertically sloped nasolabial crease
● loss of jawline contour with formation of jowls due to skin laxity and fat ptosis
● loss of submental cervical angle: midline platysma separation and band formation, skin ptosis
These changes result in loss of the arches of the face that define the youthful appearance.
Such massive structural and morphological changes involve all the tissues, but each in a different way. Laxity of the skin and subcutaneous tissues accounts only for a part.
Loss of volume, due to fat atrophy and bone remodeling, also contributes significantly to the aging process. Each tissue plays a role in facial remodeling: bone, fat, and muscle changes each affect the aging process and have their consequences on appearance.
