Which piece of equipment is also called a loupe?

A loupe is a type of magnifying glass that is used to provide enhanced visibility, and it is commonly referred to as a magnifying lamp in the context of esthetics. This equipment typically features a lens that magnifies the area being treated, allowing estheticians to perform detailed work, such as examining the skin for conditions, applying products, or performing precise treatments. The light that is often integrated into the magnifying lamp also helps illuminate the work area, making it easier to see fine details.

The other options, while important in a spa or esthetics setting, serve different functions. The steam machine is used for facial treatments to hydrate the skin, the microcurrent device is utilized for muscle stimulation and toning, and the hot towel cabinet stores towels at a warm temperature for client comfort. None of these options provides the magnification that a loupe does.
