As a dermatologist with a keen interest in skin physiology, I am delighted to delve into the fascinating world of sebum. The sebaceous glands, found throughout the skin, are an integral part of our body's integumentary system. They are responsible for the production and secretion of sebum, a substance that plays a crucial role in maintaining the health and function of our skin and hair.
Sebum is an oily, waxy substance that is composed of a complex mixture of lipids, including triglycerides, wax esters, squalene, and the metabolites of sebocytes—the cells that produce sebum. This substance has several important functions that contribute to the overall well-being of our skin and hair.
1. Protection: One of the primary functions of sebum is to provide a protective barrier for the skin. It helps to waterproof the skin, preventing excessive moisture loss and keeping the skin hydrated. This is particularly important in maintaining the skin's integrity and preventing it from becoming dry and cracked.
2. Lubrication: Sebum acts as a natural lubricant, reducing friction between the skin and hair. This is essential for maintaining the flexibility and suppleness of the skin, as well as for preventing hair from becoming brittle and prone to breakage.
3. Antimicrobial Properties: Sebum has antimicrobial properties, which can help to inhibit the growth of certain bacteria on the skin. This is an important defense mechanism that helps to protect the skin from infections.
4. Pheromone Carrier: Sebum also serves as a carrier for pheromones, the chemical signals that mammals use to communicate with each other. These signals can influence various social behaviors and are an essential part of the mating process.
5. Thermoregulation: The secretion of sebum can also play a role in thermoregulation. By varying the amount of sebum produced, the body can help to regulate its temperature, particularly in response to environmental changes.
6. Skin Repair: Sebum contains components that are beneficial for the repair and regeneration of skin cells. It helps to maintain the skin's natural repair mechanisms, promoting healing and preventing the formation of scars.
7. Acid Mantle Maintenance: The acidic pH of sebum helps to maintain the skin's acid mantle, which is a slightly acidic layer on the skin's surface. This acid mantle is crucial for maintaining the skin's barrier function and preventing the invasion of pathogens.
Despite its many benefits, an imbalance in sebum production can lead to various skin conditions, such as acne, which is characterized by the overproduction of sebum and the clogging of hair follicles. It is therefore essential to maintain a healthy balance of sebum for optimal skin health.
Understanding the role of sebum is not only important for dermatologists but also for anyone interested in skincare. By appreciating the multifaceted functions of sebum, we can better appreciate the complexity of our skin's natural processes and the importance of maintaining a healthy skin barrier.

Function. Sebaceous glands secrete the oily, waxy substance called sebum (Latin: fat, tallow) that is made of triglycerides, wax esters, squalene, and metabolites of fat-producing cells. Sebum waterproofs and lubricates the skin and hair of mammals.
