Sebaceous Glands: Structure and Role in Skin Health
The sebaceous glands are small, exocrine glands located in the dermis layer of the skin. They are responsible for secreting sebum, an oily substance that plays a crucial role in maintaining skin hydration and protecting against pathogens.
Anatomy and Function
- Location: Found throughout the body, except on the palms and soles.
- Structure: Glands connected to hair follicles, releasing sebum through the follicular ducts.
- Function: Regulates moisture, prevents bacterial infections, and contributes to skin elasticity.
Common Disorders of Sebaceous Glands
Dysfunction of sebaceous glands can lead to various dermatological conditions, including:
- Acne: Overproduction of sebum leading to clogged pores and bacterial growth.
- Seborrheic Dermatitis: Excessive sebum secretion causing flaky and inflamed skin.
- Steatocystoma: Benign cystic growths related to sebaceous glands.
Maintaining Sebaceous Gland Health
Proper skincare and balanced nutrition help regulate sebum production and prevent gland-related issues. Dermatological treatments can also aid in managing excessive or deficient secretion.
