What do sebaceous glands secrete?

Sebaceous glands are specialized structures in the skin responsible for producing and secreting an oily substance known as sebum. This oil plays a critical role in maintaining the health of the skin and hair by providing moisture and creating a protective barrier against external environmental factors. Sebum helps to keep the skin hydrated, prevents desiccation, and has antibacterial properties that can help protect against infections.

The secretion of oil, or sebum, is typically stimulated by hormonal changes, particularly androgens, which is why people may experience increased oil production during puberty. This natural oil works in conjunction with other components of the skin to promote overall skin health and a smooth texture.

While hormones, enzymes, and sweat are all important in various bodily functions, they do not pertain to the secretion of sebaceous glands. Hormones are produced by endocrine glands, enzymes facilitate biochemical reactions, and sweat is secreted by sweat glands, each serving distinct purposes in the body. Understanding the specific role of sebaceous glands emphasizes their importance in skincare and overall dermatological health.
