Sebum is part of the fat found on the surface of the skin. Other components of oil on the skin are sweat, lipids and environmental impurities. It is the oil that contributes a lot to our body odor. The sebum itself is odorless, but its bacterial breakdown causes the odor. This is why by regularly keeping your skin free of bacteria with antibacterial soaps, you can reduce body odor to a great extent. Sebum gets into the hair follicles
and covers the hair and also enters the skin through the hair follicles. Many people experience greasy hair if left unwashed for days. This happens because of sebum. The Latin meaning of fat is fat.
How sebum is formed – sebum is produced by the sebaceous glands. These glands are found on most parts of the body. Except for a few, most sebaceous glands drain into the hair follicle. These are the sites of acne formation.
What ointment- transdermal ointment protects the skin from bacterial infection. Sebum also reduces the natural loss of body water from the skin. Increased sebum production can cause acne.
Sebum production – sebum production decreases with age. Especially in women, it decreases after menopause. Adult women produce less sebum than men. Sebum production can spike during puberty in men.
There are several general theories about sebum. Some people believe that drying up excess sebum with absorbent oils will reduce sebum production. Some believe that if you use products that are supposed to control oil production, sebum production will increase. Both are false conclusions. Drying the excess oil will only remove the surface oil. And using oil control products will not increase sebum production. Sebum is needed to protect our skin, but increased sebum production leads to oily skin and frequent acne flare-ups.

Acne is a disorder of hair follicles and sebaceous glands (sebaceous glands). Sebaceous glands secrete oils (sebum) to keep the skin moist. When the glands become clogged, it can lead to pimples and cysts.
Bottom Line. Sebum is an essential part of healthy skin. It hydrates and protects the surface of almost your entire body. But it is possible to have too much of a good thing, or too little
Sebum is an oily, waxy substance produced by your body's oil glands. Covers, hydrates and protects your skin.
It is also a major component of what you might think of as your body's natural oils.
So what exactly does sebum consist of? As an article from Harvard Medical School explains, "sebum is a complex mixture of fatty acids, sugars, waxes, and other natural chemicals that form a protective barrier against water evaporation."
To be more specific, sebum contains triglycerides and fatty acids (57%), wax esters (26%), squalene (12%) and cholesterol (4.5%).
If you have very oily skin, your body may produce an excessive amount of a mixture of lipids (fat-like molecules) that make up sebum.
Of course, what we call "oil" on our skin is made up of more than just sebum. It also contains a mix of sweat, dead skin cells, and tiny particles of just about anything else in the dust floating around you.
Where are the sebaceous glands located?
Sebaceous glands cover the vast majority of your body. Although they are often grouped around hair follicles, many of them exist independently.
Your face and scalp contain the highest concentration of glands. Your face in particular can have up to 900 oil glands per square centimeter of skin.
Your shins and other smooth surfaces usually have fewer glands. The palms of the hands and soles of the feet are the only areas of skin without any glands.
Each gland secretes sebum, and to better visualize this process, it might be helpful to think about your tear ducts and the way they secrete the natural moisture in your eyes.
Although the sebaceous glands are much smaller than the tear ducts, they function similarly.
