Sebaceous Glands
Discover the fascinating world of sebaceous glands and their crucial role
in maintaining healthy skin.
What are sebaceous glands?
Sebaceous glands are small, oil-producing glands located in the dermis of
the skin. They are connected to hair follicles and play a vital role in
protecting and lubricating the skin.
As an outgrown from upper portion of the hair follicle.
Sebum Production is an indicator of androgenic activity & increase at the
time of puberty.
Function of sebaceous glands
1 Sebum production
Sebaceous glands produce sebum,
an oily substance that moisturizes
and waterproofs the skin.
2 Protective barrier
Sebum forms a protective barrier on
the skin's surface, preventing
excessive moisture loss and
shielding against harmful
microorganisms.
3 Hair lubrication
Sebaceous glands secrete sebum onto the hair shaft, keeping it soft, shiny, and free
from tangles.
Distribution of sebaceous glands
Sebaceous glands are found throughout the body, except for the palms of the hands and soles of the
feet. The density of sebaceous glands varies in different areas, such as the scalp, face, and back.
Composition of sebum
Sebum is composed of various lipids, including triglycerides, wax esters,
and free fatty acids. It also contains cholesterol, squalene, and other
substances that contribute to its unique properties.
Role of sebaceous glands in skin health
1 Moisturization
Sebum moisturizes the skin, preventing dryness and maintaining its natural suppleness.
2 Bactericidal action
Sebum's antimicrobial properties help protect the skin from harmful bacteria and other
pathogens.
3 Aging prevention
Sebum helps minimize the appearance of fine lines and wrinkles, keeping the skin
youthful and radiant.
Sebaceous gland disorders
Acne
Excessive sebum production
can lead to clogged pores
and acne breakouts.
Sebaceous
Hyperplasia
Sebaceous hyperplasia is a
benign condition
characterized by enlarged
sebaceous glands.
Seborrheic
Dermatitis
Seborrheic dermatitis is a
chronic skin condition that
causes excessive sebum
production, resulting in flaky
and inflamed skin.
Conclusion
Sebaceous glands are essential for maintaining healthy skin, providing moisturization, protection, and
other vital functions. Understanding their role helps us take better care of our skin.
