Structural Facial Anatomy: The 5 Layers, Retaining Ligaments & Histology

A deep dive into the structural architecture of the face. This lesson breaks down the five primary facial layers, examining the specific topography, functions, and clinical differences between superficial (Layer 2) and deep (Layer 4) fat pads. You will analyze the vertical anchoring system, including the SMAS, retinacula cutis, and retaining ligaments. Finally, the lesson addresses anatomical and histological variations across skin types, adipose compartments, and deep structural layers to refine diagnostic accuracy.
