Ageing of the human face is the consequence of both, external textural folds of the epidermis, and changes in the 3-dimensional (3-D) topography of the underlying structures.
It results because of the transformation witnessed in several types of tissues: skin, fat, muscle, and bone. Changes in any one of these structural layers, affect the other layers.
Facial ageing reflects the dynamic, cumulative effects of time on the skin, soft tissues, and deep structural components of the face. It is a complex synergy of skin textural changes and loss of facial volume. Many of the signs of facial ageing reflect the combined effects of gravity, progressive bone resorption, decreased tissue elasticity, and redistribution of subcutaneous fullness. And as the Hyaluronic Acid production slows down, the face looks duller and dehydrated, with the formation of fine lines and wrinkles on the skin.
The ageing hallmarks are important when deciding on age-appropriate cosmetic intervention.
