Sebum is an oily substance produced by your body's sebaceous glands. These glands are located in your hair follicles and are most concentrated on your face and scalp. Sebum serves to protect and hydrate your skin, but too much sebum production can lead to acne, oily skin, and an oily scalp.
Sebum is primarily composed of lipids, which are fat molecules that help to keep your skin moisturized. It also contains other substances, such as wax esters, squalene, and cholesterol.
Here are some key functions of sebum:
- Protection: Sebum acts as a barrier against bacteria and other harmful substances.
- Hydration: Sebum helps to keep your skin moisturized, preventing dryness and flakiness.
- Lubrication: Sebum helps to keep your hair and skin smooth and supple.
Sebum production is influenced by various factors, including hormones, age, and genetics. Some people naturally produce more sebum than others, and this can contribute to oily skin and hair.
