I am 62 and have been noticing for a few years the decent in my lower face. I am pretty apprehensive about getting a facelift and have been doing some research. What does SMAS mean? I keep seeing this term.
SMAS is an acronym for submuscular aponeurotic system. It is the fascial layer which envelops facial fat pads and musculature and becomes the platysma muscle in the neck. This is the layer which is elevated deep to the skin and tightened during a facelift.
