Sebum production refers to the natural secretion of an oily substance from sebaceous glands in the skin. These glands are found all over the body, but they are most numerous on the face, neck and scalp. Sebum is composed mainly of lipids (fats) and serves several important functions:
1. Moisturizing: Sebum helps to keep the skin hydrated by forming a protective layer that prevents water loss. This is particularly important in areas such as the lips and eyelids, where there are no sweat glands to help regulate moisture levels.
2. Protection: The lipids in sebum have antimicrobial properties, which can help prevent the growth of bacteria on the skin's surface. This is important for maintaining healthy skin and preventing conditions such as acne or dermatitis.
3. Lubrication: Sebum helps to lubricate the skin, making it more supple and reducing friction during movement. This can help protect the skin from irritation and damage.
However, excessive sebum production can lead to problems such as acne or oily skin. Therefore, maintaining a balance of sebum production is important for healthy skin.
