What is the primary function of sebaceous glands?

The primary function of sebaceous glands is to produce sebum, which is an oily substance that plays a crucial role in maintaining the health of the skin and hair. Sebum serves several important purposes: it helps to keep the skin moisturized, provides a protective barrier against bacteria and environmental damage, and maintains the suppleness of hair. The production of sebum is influenced by various factors, including hormonal changes and overall skin health.

Sebaceous glands are found throughout the body, except for the palms of the hands and soles of the feet, indicating their wide distribution and importance in skin care. Their secretion helps prevent dryness and can contribute to maintaining the acid mantle of the skin, which is essential for skin health. Understanding the function of these glands is vital for anyone in the field of aesthetics or manicuring, as it relates directly to the care and treatment of the skin and nails.
