The Facial Adipose Tissue: A Revision

The document reviews the current understanding of facial fat compartments, highlighting their importance in facial aging and the effects of treatments like soft tissue fillers and fat grafting. It identifies three types of facial adipose tissue—fibrous, structural, and deposit—each with distinct characteristics in terms of adipocyte size and extracellular matrix composition, which affect their mechanical properties. The review emphasizes that these differences should be considered during minimal invasive and surgical interventions aimed at rejuvenating the face. However, it also notes that there is a lack of detailed knowledge about the macroscopic and microscopic properties of these fat compartments, suggesting a need for future research to improve anti-aging treatments.
