Which type of ultraviolet light is primarily used in tanning beds?

• A. UVC light
• B. UVB light
• C. UVA light
• D. Infrared light

Answer: (C)

UVA light is primarily used in tanning beds because it penetrates the skin more deeply than UVB light and is responsible for the immediate tanning effect. Unlike UVB light, which is associated with sunburn and more intense erythema, UVA light stimulates the production of melanin in the skin, resulting in a tan. Furthermore, while UVA is less intense than UVB, its longer wavelengths can lead to skin damage and increase the risk of skin aging and cancer over time. In contrast, UVC light is mainly filtered out by the Earth’s atmosphere and is not used in tanning beds. UVB light is more involved in producing a sunburn and is not the primary component of tanning. Infrared light does not contribute to tanning; rather, it provides heat without affecting skin pigmentation. Therefore, UVA light is the correct answer for the type of ultraviolet light primarily employed in tanning beds for tanning purposes.
