What Are Sebaceous Glands?

Sebaceous glands, found in the skin, produce and release sebum, a substance that forms a protective layer on the skin to aid in moisture retention. The majority of these glands are connected to hair follicles.

What Are The Types Of Sebaceous Glands?

There are two categories of sebaceous glands, each situated in different areas of your body:

  1. Sebaceous glands are connected to your hair follicles.
  2. Sebaceous glands are not attached to your hair follicles.

Most of your sebaceous glands are connected to your hair follicles through openings. However, certain sebaceous glands collaborate with sweat glands and release their contents directly onto the surface of your skin rather than through the hair follicles. Despite this difference, both types serve the same purpose, producing and releasing sebum.

What Is The Function Of Sebaceous Glands?

Sebaceous glands play a role in generating and releasing sebum, an oily substance composed of lipid molecules, which encompass:

  1. Cholesterol.
  2. Fatty acids.
  3. Glycerides.
  4. Squalene.
  5. Wax.

Where Are Sebaceous Glands Located On My Body?

Sebaceous glands form in or around your hair follicles within the second layer of your skin, known as the dermis. Throughout your body, you possess thousands of sebaceous glands, except for the palms of your hands and the soles of your feet. The highest concentration of sebaceous glands is found on your face and scalp. Additionally, sebaceous glands not connected to hair follicles are prevalent on your penis, labia, lips, or inside your nose.

Various conditions can impact the well-being and operation of your sebaceous glands. Among the most prevalent are:

  1. Acne: A widespread skin condition leading to the formation of pimples on your face, chest, shoulders, or upper back. Acne often results from factors such as pores being obstructed by sebum (sebum plug).
  2. Hyperplasia: Sebaceous hyperplasia is a benign skin condition arising from overactive sebaceous glands.
  3. Sebaceous cysts: These are growths beneath your skin, filled with sebum fluid as they develop in the sebaceous glands.
  4. Sebaceous carcinoma: A rare form of cancer originating in the sebaceous glands of the skin, leading to the formation of a solid yellow lump on the eyelid.
  5. Sebaceous filaments: These result from excess production of sebum, enlarging the pores on your skin and causing them to fill with sebum and dead skin cells around the hair follicles. Sebaceous filaments have a similar appearance to blackheads.

What Are Common Signs Or Symptoms Of Sebaceous Glands?

While the majority of sebaceous glands may not exhibit symptoms, the signs and symptoms can differ for each condition and may involve:

  1. Pimples on the skin.
  2. A red to purple bump on the skin.
  3. A solid lump or bump that is easily movable beneath the skin.
  4. Enlarged pores filled with a solid, black substance.
  5. A white pustule or a small, fluid-filled bump on the skin where hair grows.
  6. Oily or greasy hair or skin.

What Are Common Treatments For Sebaceous Gland Conditions?

Treatment approaches differ for each condition and may involve:

  1. Surgical removal of a cyst or cancer.
  2. Administration of medication (oral or topical) to alleviate acne.
  3. Laser or light therapy utilizing bright lights to repair damaged skin.
  4. Cryotherapy, involving the freezing of skin blemishes, causing them to dry up and disappear.

How can I keep my sebaceous glands healthy?

Maintaining the health of your sebaceous glands and preventing the blockage of hair follicles and glands can be achieved by:

  1. Use a mild cleanser on your skin every day.
  2. Utilizing skincare products that include salicylic acid.
  3. Apply moisturizers regularly.
  4. Using sunscreen when venturing outdoors.

Additionally, ensuring the health of your sebaceous glands involves staying hydrated and drinking an ample amount of water throughout the day.


What is the difference between the sebaceous gland and the oil gland?

What sets apart the sebaceous gland from the oil gland? Sebaceous glands, often referred to as oil glands, are responsible for secreting oil in your body. They belong to the category of holocrine simple saccular (alveolar) glands. Their primary function is to release a substance known as sebum, which consists of a blend of fatty substances, complete sebum-producing cells, and debris from epithelial cells.

What stimulates sebaceous glands?

What activates sebaceous glands? Sebaceous gland function is regulated by androgens, which bind to nuclear androgen receptors (AR). These receptors are found in various skin components, with a specific affinity for the sebaceous gland. In this gland, androgens stimulate cell proliferation and lipogenesis.

Can you squeeze out a sebaceous gland?

Attempting to pop a sebaceous cyst at home may elevate the risk of inflammation, infection, and discomfort. In brief, it is advisable to have such cysts removed by a doctor.

The Bottom Line

Sebaceous glands play a crucial role in maintaining skin moisture. While greasy hair or oily skin may be bothersome, they are indicators that your sebaceous glands are functioning. Establishing a daily skincare routine is essential to prevent pores and hair follicles from becoming clogged with excess sebum.
