Society values cleanliness as evidenced by our frequent washing, and the volume of creams, conditioners, lotions, and moisturizers we buy. What secretion are we removing with frequent washing and why is that secretion important for the skin?
What will be an ideal response?
Frequent washing removes sebum from the epidermis of the skin. Sebum, produced by sebaceous glands, coats the surface of the skin and hair. It helps keep skin moist by providing a hydrophobic barrier that prevents water from leaving it. Sebum also kills certain bacteria and deters their growth.
