What are Sebaceous Glands?
There has been a lot of talk about the Sebacious Glands and their relationship to skin care. These small microscopic glands are responsible for depositing an oily secretion on the hairs called sebum.
Where are Sebaceous Glands located?
Sebaceous Glands are normally located on areas of the human body associated with hair follicles. These glands are located on areas like the face, scalp, chest and back. These mature and start active production of sebum when there is an onset of puberty in the person.
The exception would be the soles of the feet and the palms of the hand. Other areas you would not find sebaceous glands would be the eyes, nipples, Labia Minora, penis and nose.
What is the function of Sebaceous Gland?
Your skin is protected by the properly functioning of the Sebaceous Glands. They secrete an oily substance known as Sebum. Sebum is a lubricant for the hair and skin. It’s primary job is the protection of the skin and hair from water. And, sebum is usually visible in large quantities. It also reduces the development of microorganisms which try to invade the three layers of the skin; the dermis, the epidermis, and the subcutaneous fat layer.
Sebum provides the ability for you to experience moist skin even though you may not have bathed for a few days.
Fact: Approximately 3 thousand Sebaceous Glands can be found per square inch of the skin.
What are sebaceous cysts or a sebaceous gland cyst?
A sebaceous cyst is a epidermoid cysts (also known as epidermal cysts) or pilar cysts (also known as trichilemmal cysts). Because an epidermoid cyst originates in the epidermis and a pilar cyst originates from hair follicles, by definition, neither type of cyst is strictly a sebaceous cyst.
