Sebaceous Gland

Meaning

The sebaceous gland is a small, specialized exocrine gland located within the dermis of the skin, most commonly associated with hair follicles. Its primary physiological role is the synthesis and secretion of sebum, a complex mixture of lipids that serves to lubricate the skin and hair, providing a protective barrier against moisture loss and microbial colonization. The activity of this gland is profoundly sensitive to hormonal fluctuations, particularly those involving androgens, making it a key component of dermatological and hormonal health.
