Which of the following must working areas or clinical areas be constructed from?

Working areas or clinical areas in cosmetology must be constructed from smooth and non-absorbent durable materials to maintain hygiene and safety standards. These materials prevent the absorption of liquids, which can harbor bacteria and other pathogens, thereby ensuring a clean environment conducive to client services. Smooth surfaces are easier to clean and disinfect, reducing the risk of contamination and infection, which is critical in any setting that involves skin contact and cosmetic procedures.

Choosing smooth and non-absorbent materials also contributes to the overall durability and maintenance of the workspace. Unlike textured or absorbent materials, which can wear down over time or become stained, smooth surfaces maintain their integrity and appearance, supporting a professional atmosphere.

Other materials, such as metal and glass, while aesthetically pleasing, may not offer the same practical benefits in terms of hygiene and comfort, especially in a setting where clients may be seating and where heavy use is expected. Thus, the focus on smooth, non-absorbent, and durable materials is essential in ensuring compliance with health standards and enhancing the overall client experience.
