Define the term "tanning bed."

The definition of "tanning bed" refers to a device that emits ultraviolet (UV) radiation, which is essential for stimulating the production of melanin in the skin, responsible for the cosmetic tan. Tanning beds operate by utilizing specific wavelengths of UV light to achieve this effect, allowing individuals to obtain a tan without direct exposure to sunlight.

Understanding this definition is crucial, especially in the context of skin health and safety, as it highlights the tanning bed's intended purpose compared to other options that focus on different skincare functions, such as exfoliation, hydration, or outdoor tanning applications. The other alternatives do not accurately represent the function of a tanning bed, as they pertain to different facets of skincare rather than the specific process of tanning through UV exposure.
