Also Known as Subcutaneous Tissue, the Hypodermis Regulates Body Temperature.

Definition: Hypodermis is the lowermost layer of skin. Also known as subcutaneous tissue, the hypodermis contains the cells known as fibroblasts, adipose cells and macrophages. The hypodermis is used for the storage of fat but is composed of nerves and blood vessels that are larger than those found in the dermis. The hypodermis binds the dermis to the underlying organs.

The function of the hypodermis is to store lipids and insulate and cushion the body.

It also serves to regulate body temperature. Hair follicle roots are located in the hypodermis.

While the hypodermis is not visible, the hypodermis can have a dramatic effect on the appearance of the skin and the way aging impacts the skin, specifically in the area of the face and neck. With aging, the volume of facial fat decrease and the areas of the face have less supportive tissue. The facial skin begins to droop and sag resulting in a look that can be interpreted as tired. The bones and muscles of the face also lose volume.

To correct the loss of facial volume and counteract the effects of aging, hyaluronic acid fillers, used specifically for volume replacement, can be used.  Hyaluronic acid is compatible with the body and may be a good choice for facial filler. It is found naturally in the body with high concentrations in soft connective tissue and the fluid that surrounds the eyes.

It is also found in cartilage and joint fluids.

An injection of hyaluronic acid filler will support facial structures and tissues that have lost volume and elasticity. It acts as a volumizer by bringing water to the surface of the skin to making it look more supple and fresh. It plumps and lifts cheeks, jawlines and temples.

It can fill out thin lips and plump hands that have begun to sag.

While side effects are rare, there are risks to injections of hyaluronic acid. There could be a risk of an allergic reaction and bumps under the skin.
