The subcutaneous tissue is the last of our skin layers to review. This layer contains a lot of blood vessels and nerves, and provides a lot of support to the skin above. This layer is made up primarily of fat lobules, held together with Collagen bundles.
The subcutaneous tissue layer is where you get a lot of your shots, and although technically this is a layer of fat underneath the skin itself, this layer is extremely important to the look of your skin. Too little (think of an aging face) and things start to appear sunken and the skin is loose. There really isn’t too much else to say about the subcutaneous tissue.
