The SMAS Layer and why it's important
SMAS layer in a facelift.
SMAS is actually an abbreviation for a tissue layer called the Sub-Muscular Aponeurotic System. As this is a mouthful, most patients and surgeons use the acronym “SMAS”. The SMAS is a relatively thin layer of strong fascial supporting tissue that covers and surrounds the deeper tissues and structures of the face and neck including fat pads and muscles of facial expression, including the entire cheek area. It also attaches to the superficial muscle covering the lower face near the jaw line and neck called the platysma. As the SMAS attaches to all of these areas of the face, a SMAS lift surgically elevates this layer which in turn repositions the soft tissues and structures of the face to an elevated more youthful position

Layers of the SMAS
The SMAS is a single layer of fascia which is directionally organized collagen and ground substance, it is quite thin but invests or wraps around the tissues of the face and neck. It can be lifted in order to suspend the tissue of the cheek and neck into a better position.
Kinds of tissue in the SMAS layer
The SMAS (superficial musculo-aponeurotic system) is a dense layer of fascia that envelops the muscles of facial expression and is contiguous with the platysma muscle in the neck. It is this layer that is utilized during a facelift procedure to allow for a more natural-appearing result. In my practice, to achieve a natural, more youthful look, I perform an extended sub-SMAS elevation that continues low into the neck in the subplatysmal plane in conjunction with neck liposuction. The result is a smooth, rejuvinated face and neck with excellent contour of the neck and jawline.
SMAS stands for "superficial musculo-aponeurotic system" and is shorthand for the connective tissue layer in the face that is generally considered an extension of the platysma muscle in the neck and connects to other structures in the face. It is fascia and not fat but it can move attached fat. Aging faces lose tone in the skin and connective tissue such as the SMAS layer so it is adjusted during facelifting procedures to provide a "tighter" base on which the skin is lifted above it.

SMAS layer during Face Lift
This is a point of some debate but after 20 years of performing Face Lifts and manipulating the SMAS, IMHO this consist of the vestigual muscle that's continuous with the Platysma muscle, in the neck and the Parotid Fascia.
