Which components are found in sebum?

Sebum is a natural oil produced by sebaceous glands in the skin, primarily responsible for lubricating and protecting the skin and hair. The correct choice highlights the specific components that make up sebum: triglycerides, cholesterol, ester waxes, and squalene.

Triglycerides are a type of fat that serves as a significant energy source and helps maintain skin hydration by preventing moisture loss. Cholesterol is essential for maintaining the structure and integrity of cell membranes and also adds to the lipid barrier function of the skin. Ester waxes contribute to the texture and pliability of sebum, while squalene acts as an antioxidant and has moisturizing properties that help protect the skin from environmental damage.

Each of these components plays a vital role in the overall health and appearance of the skin and hair, reinforcing why they are included in the composition of sebum. Understanding the constituents of sebum is crucial for nail technicians and professionals in skin care, as it relates to skin health and the products they may use or recommend.
