What is the difference between hypodermis and fascia?
The subcutaneous tissue, also known as the hypodermis or superficial fascia, is the layer of tissue that underlies the skin. The terms originate from subcutaneous in Latin and hypoderm in Greek, both of which mean “beneath the skin,” as it is the deepest layer that rests just above the deep fascia.Feb 27, 2019

What Is The Hypodermis?
Skin is divided into three layers - epidermis, dermis, and the hypodermis. The hypodermis is the deepest layer of your skin, also known as subcuta neous fascia. The term subcutaneous is in Latin and hypoderm in Greek, both of which means ‘beneath the skin’. The layer sits above the deep fascia (dense connective tissue that can surround individual muscles).
How Does The Hypodermis Protect Your Body?
It is made up of adipose tissue or fat cells and connective tissue. The dermis or the middle layer of your skin folds and bulges into the hypodermis. These areas have tiny cavities that are filled with fat and water. These fat layers act as shock absorbers for your body. It protects the underlying bones from mechanical injuries.
What hormones are produced by the hypodermis?
The fat cells in the hypodermis produce hormones like leptin that regulates your energy balance. Hypodermis also stimulates the essential vitamin D when you are exposed to sunlight. [ 4] Although the hypodermis is deep-seated within your skin, you can notice its impact on your skin as you age.

The adipose tissue present in the hypodermis layer of the skin stores fat and reserves energy. 2. Safeguards Your Body From Mechanical Injuries. The fat cells present in the hypodermis protect the body from getting hurt. It acts as a shock absorber for the internal organs of the body. [ 2]
Which layer of the body is made of fat?
The hypodermis is the deepest layer of the skin. It is made of subcutaneous fat composed of adipose cells and is surrounded by connective tissue, nerves, and blood vessels. [ 5] . The number of adipose cells varies with the area of the body. The size of the adipose cells varies too and depends on the nutrition of the person.
Which layer of the body produces leptin?
The adipose tissue in the hypodermis layer produces a leptin hormone [ 3 ], that is known to regulate your body’s energy balance. It prevents you from overeating by sending signals to your brain.

There are technically 6-7 named layers of the skin depending on where are on the body that are visible under the microscope. The hypodermis or subcutaneous fat is not really part of it. From the name as well hypodermis means under the skin.
What is the outermost layer of the epidermis?
Stratum corneum: This is the outermost or top layer of the epidermis. It's made of dead, flat keratinocytes that shed approximately every two weeks. The epidermis contains three specialized cells: Langerhans cells that act as the first line of defense in the skin's immune system.

How can I protect my skin?
You lose collagen and elastin as you age. This causes the skin’s middle layer (dermis) to get thinner. As a result, the skin may sag and develop wrinkles.
What are the proteins in the skin?
What are the skin’s proteins? 1 Collagen: Collagen is the most plentiful protein in the skin, making up 75-80% of your skin. Collagen and elastin are responsible for warding off wrinkles and fine lines. Over time, the environment and aging reduce your body’s ability to produce collagen. 2 Elastin: Think elastic. Elastin is found with collagen in the dermis. It’s another protein, responsible for giving structure to your skin and organs. As with collagen, elastin is affected by time and the elements. Lower levels of this protein cause your skin to wrinkle and sag. 3 Keratin: Keratin is the main protein in your skin, and makes up hair, nails, and the surface layer of the skin. Keratin is what forms the rigidity of your skin and helps with the barrier protection that your skin offers.
What are the two proteins that are needed for skin health?
Here, you’ll find collagen and elastin, 2 proteins necessary for skin health because they offer support and elasticity (your skin’s ability to go back to its original state after being stretched). Fibroblasts are the cells you’ll find in this layer, because they synthesize collagen and elastin.
What is the layer of skin that gives it its fullness and plumpness?
The dermis is the layer that gives your skin its fullness and plumpness. Age and the sun can damage the dermis and lead to wrinkles. The dermis is a complex combination of blood vessels, hair follicles, and sebaceous (oil) glands.

Function
- The hypodermis may at first be viewed as tissue which is used primarily for the storage of fat, but it has other important functions as well. These functions include: 1. Storing fat (energy storage) 2. Protection (think buttocks and sitting on a hard chair) 3. Attaching the upper skin layers (dermis and epidermis) to underlying tissues such as your bones and cartilage, and supporting the struct…
Conditions Which Affect The Hypodermis
- There are several medical disorders and medical procedures which are related to this unique layer of the skin: Hypothermia and Overheating: The thinning of the hypodermis with age is one of the reasons that older people are more prone to hypothermia. If you are ordinarily hot, this news is not necessarily so good. The thinning of the hypodermis also may mean that you sweat less, and a l…
The Hypodermis and Aging
- While the hypodermis is not visible, it 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 decreases and there is less supportive tissue to support the normal turgor and elasticity of the skin. The facial skin begins to droop and sag resulting in a look that can be i…
