Sebum is the oily or waxy substance secreted by your sebaceous glands. These glands are found all over your body except for your palms and soles, and they pump out sebum to protect your skin from moisture loss.
Sebum is made up of a cocktail of triglycerides, wax esters, squalene and free fatty acids. It’s usually pale yellow or white in color and it has a slightly bitter taste.
Sebum is created in the sebaceous glands by combining together lipids with cellular debris, that’s dead skin cells to you and me. Sebum is primarily composed of triglycerides, wax esters, squalene and free fatty acids. Triglycerides are made up of three fatty acid molecules bound together by glycerol.
The function of triglycerides can vary according to their size and the carbon chain length of their three constituent fatty acids. Smaller clinically relevant triglyceride molecules have been shown to have moisturizing properties whereas larger triglyceride molecules are thought to have occlusive properties that prevent water loss from the skin.
Wax esters consist of two long hydrocarbon chains linked by an ester bond. They’re found naturally in coconut oil, olive oil and beeswax
Sebum is an oily substance formed by sebaceous glands in mammals. These glands exist everywhere except the palms of hands and soles of feet. The glands are found in the greatest number on the face and scalp, but also on all parts of the skin except the palms and soles. Sebum is made within the sebaceous gland, which is located within the hair follicle. Sebum acts to protect hair and skin, and keep them from becoming dry, brittle, and cracked. It is odorless[citation needed], but its bactericidal properties yield a characteristic scent in those with an uninhibited olfactory sense.
Sebaceous glands are microscopic and their structure can be seen only with the help of a microscope. They secrete an oily or waxy matter, called sebum, to lubricate and waterproof the skin and hair of mammals. Sebaceous glands are found over almost all of the body except for a few areas such as lips, nipples and parts of the external genitalia. Sebum is made within the sebaceous gland that is located within each hair follicle (also known as pilosebaceous unit). The sebum travels up along the hair follicle until it exits onto the surface of your skin through pores.[
Sebum is a mixture of lipids[2] that is emitted by sebaceous glands in the skin of mammals. In humans, sebum is the chief cause of acne. Sebum plays a helpful role in keeping skin and hair waterproof and keeping skin soft, although the oily nature of the substance may lead to the accumulation of dirt and bacteria, leading to body odor.[3] Sebum acts to protect hair and skin, and can inhibit the growth of microorganisms on skin.
Sebum has an odor, however whether its role is to attract mates or repel predators is not known.
The word “sebum” comes from Latin for tallow or lard.[4][5]
Sebum is an oily/waxy substance produced by sebaceous glands at the base of hair follicles. Its composition varies depending on where it is being produced, but generally contains triglycerides, wax esters, squalene and fatty acids.
Sebum acts as a water-proofing agent to protect skin and hair from dehydration while also contributing to the fauna of the skin which keep pathogens in check. Sebum also possesses some antimicrobial properties which help prevent skin infections.
When sebum production is excessive or when sebaceous glands become clogged with dead skin cells, it can cause acne breakouts. Conversely, too little sebum production can lead to dry, flaky skin and dandruff.
Sebum is an oily or waxy matter that is secreted by the sebaceous glands. It consists of triglycerides, wax monoesters, squalene, and cholesterol esters. Sebum acts to protect hair and skin, and can be a food source for commensal skin flora. Hyposebaceous and hypersebaceous are clinical terms used to describe low levels of sebum production (hyposebaceous) or high levels of sebum production (hypersebaceous).
