Question: 1 / 400

What function does sebum provide for the skin?

Blocks pores and causes acne

Acts as a preservative in skin products

Keeps the skin soft, supple, and pliable

This natural oil, produced by the sebaceous glands, forms a protective barrier on the skin's surface, preventing moisture loss and helping to maintain hydration. By doing so, sebum ensures that the skin retains its elasticity and stays resilient against environmental factors. This function is vital for overall skin health, as dry or cracked skin can lead to irritation and other issues. The other choices, although they contain some truth, do not accurately reflect the primary beneficial role of sebum for skin health.
