What is the function of sebum?

The normal function of sebaceous glands is to produce and secrete sebum, a group of complex oils including triglycerides and fatty acid breakdown products, wax esters, squalene, cholesterol esters and cholesterol. Sebum lubricates the skin to protect against friction and makes it more impervious to moisture.

Does sebum prevent pathogens?

Sebum is an oily substance produced in the sebaceous glands. It mixes with fat molecules, called lipids, to form a protective coating on the skin’s surface. These lipids help hydrate the skin and protect it from potentially harmful pathogens, such as bacteria and fungi.

What does the skin prevent from entering the body?

The skin acts as an external barrier to bacteria, preventing infection and protecting the internal organs. The skin also protects the body from ultraviolet radiation using the pigment barrier formed from melanocyte cells found in the top of the papillary dermis and a protein layer found in the epidermis.

How does sebum protect the body from pathogens?

Sebum consists of number of organic acids that maintain the pH of the skin between 3 and 5. Therefore, intact skin not only prevents entry of pathogens or hazardous chemicals but also inhibits the growth of most pathogenic bacteria due to its low pH.

What line of defense is sebum?

How does the skin prevent microorganisms from entering the body?

Identify the properties that help the skin prevent microorganisms and other foreign substances from entering the body. Select all that apply. -The lack of blood vessels in the epidermis limits access to central circulation. -Secretions from skin glands produce an environment unsuitable for some microorganisms.

What are the side effects of overproduction of sebum?

As essential as sebum is to overall health and well-being, overproduction or underproduction of it—due to hormonal fluctuations, for example—are associated with skin problems including acne, oily skin, and chronic itchiness and skin irritation.

Are there any medications that suppress the production of sebum?

Some medications for treating acne and oily skin work by suppressing sebum production; these include oral contraceptives, anti-androgens, and prescription retinoids (both orally and topical). If you have normal sebum levels to start with, you should be cautious using these medications.
