What is an example of a product used in facial supplies?

• A. Moisturizer
• B. Mask Brush
• C. Sunblock
• D. Toner

Answer: (B)

The choice of a mask brush is a valid example of a product used in facial supplies because it serves a specific purpose in the application of facial masks. Mask brushes are designed to evenly apply products such as clay masks, hydrating masks, or exfoliating masks to the skin. This tool allows for an even application, minimizing mess and ensuring that the product is spread out uniformly across the face, which can help with absorption and efficacy.

Other options like moisturizer, sunblock, and toner are indeed products that are applied to the skin during facial treatments, but they are not tools or supplies specifically associated with facial application methods like a mask brush. While they play important roles in skincare routines, the mask brush is categorized as an essential supply or tool used in the process of administering a facial treatment, enabling effective and hygienic application.
