I call this the lasagna slice, complete with hair. Basically you can follow the layers from skin down to muscle. It’s not apparent in this drawing but the thinner white layer closer to the skin (labeled the superficial fascia) is really two layers. The thick, white layer of deep fascia on top of the muscle is actually 2-3 layers of fascia. These are separated by loose connective tissue full of hyaluronan, here labeled as the hyaluronic acid layer. It’s really not such a neat, isolated layer as depicted in yellow here, but more densely scattered between each of the deep fascia layers. When properly functioning it serves to provide space and slide between these layers. (Original source unknown.)
