What is the Origin of Sebaceous Gland Activity?

The term is derived from the Latin sebum, meaning fat or grease, directly describing the gland's secretion. Clinical recognition of the gland's sensitivity to circulating hormones, especially during puberty and in conditions like polycystic ovary syndrome ($text{PCOS}$), established its significance in dermatologic and endocrine health. The gland serves as a peripheral target organ for steroid hormones.

What is the Mechanism of Sebaceous Gland Activity?

The mechanism is primarily controlled by the local and systemic concentration of androgens, such as dihydrotestosterone ($text{DHT}$). Androgens bind to receptors within the sebocytes, stimulating their proliferation and increasing the rate of lipogenesis, which is the synthesis of sebum lipids. Conversely, estrogens and anti-androgens can suppress this activity. This hormonal regulation dictates the volume and composition of the sebum secreted onto the skin surface.

Sebaceous Gland Activity

Meaning

Sebaceous gland activity refers to the physiological process of synthesizing and secreting sebum, a complex lipid mixture composed of triglycerides, wax esters, and squalene, by the sebaceous glands located in the dermis. The rate of this activity is a major determinant of skin and hair oiliness, playing a role in barrier function, hydration, and the development of acne vulgaris. This glandular function is highly sensitive to hormonal regulation, particularly by androgens.
