Age-related face changes

Our face continuously changes over years with a distinctive pattern. Generous distribution of subcutaneous fat creates the appealing contours and fullness of young faces. Atrophy and hypertrophy of the subcutaneous fat over years leads characteristics of aged faces with display jowls, tear trough deformity, and submental fullness. Facial aging can be characterized by wrinkles, loss of tissue firmness, vascular disorder and heterogeneous pigmentation. Subcutaneous fat in case of young faces allows facial muscle to glide under skin and contract without pulling it. Repeated facial gestures over years together with the cumulative UV exposure from sun leads to fibrotic connection between muscle and skin. As a result facial gestures on aged faces yield characteristic contours and wrinkles around lips, eyes and forehead.
