Understanding the Difference Between Superficial and Deep Fat Compartments of the Face

Have you ever wondered why your face looks different when you smile or make different facial expressions? It's because of the two different layers of fat compartments that exist in your face - the superficial and deep fat compartments. Understanding the difference between these two types of fat can help medical professionals choose the right dermal fillers for their patients. In this blog, we will discuss the differences between superficial and deep fat compartments and how they are affected by facial animation.


Superficial fat compartments are located right beneath the skin and are responsible for the shape and contour of the face. This type of fat is dynamic and moves with facial animation. When you smile or make other facial expressions, the muscles beneath your skin contract, causing the superficial fat compartment to move along with the skin. This movement creates subtle contours and shapes in your face. The movement of superficial fat also plays a crucial role in the aging process. As we age, we lose some of the elasticity in our skin, and the movement of superficial fat becomes less noticeable, resulting in wrinkles, sagging skin and other visible signs of aging.


Deep fat compartments, on the other hand, are located deep within the facial structure and are responsible for providing support and structure. This type of fat is static, which means it does not move with facial animation. The deep fat compartment forms a sturdy foundation, ensuring that the upper layers of the face remain supported and stable. As we age, we lose some of the volume in our deep fat compartments, which can lead to a loss of contour and the appearance of sagging skin.


When selecting a dermal filler, it's essential to consider the different types of fat compartments and how they affect the facial structure. For areas of the face where the superficial fat compartment is most important, such as the lips or cheeks, a softer, more mobile filler is recommended. On the other hand, for areas where the deep fat compartment is the most crucial, a more robust, firmer filler should be used.

What are some areas you can think of that would require a firmer filler?


It's also important to remember that not all filler products are created equal. Some products may work better in the superficial fat layer, while others may work better in the deep fat layer. It's crucial to select a product that is appropriate for the intended use and location to achieve the desired results. Additionally, as aesthetic professionals, it's also essential to understand the possible complications or risks associated with each dermal filler product and proper injection techniques.


Understanding the differences between superficial and deep fat compartments of the face and how they function is crucial when selecting the appropriate dermal filler product. Superficial fat is dynamic, while deep fat is static. Superficial fat is affected by facial animation and provides shape and contour to the face, while deep fat provides stability and support. Choosing the right dermal filler product involves selecting the appropriate type of filler, considering the intended use and location, and understanding potential complications and risks. As aesthetic professionals, it's important to have an in-depth understanding of these concepts to ensure patients receive the best possible treatment outcomes.
