What is the function of sebaceous glands?

The function of sebaceous glands is to secrete sebum, which is an oily substance that plays a critical role in skin health. Sebum helps to lubricate the skin and hair, providing a barrier that prevents water loss and protects against dryness. It also has antimicrobial properties, which contribute to the skin's defense against harmful microorganisms.

Understanding this function is crucial in the context of esthetics, as an imbalance in sebum production can lead to various skin conditions, such as acne or excessively dry skin. Recognizing how sebaceous glands contribute to overall skin health can enhance the effectiveness of skincare treatments and routines.
