What is a benefit of using both levels of UV tanning?

Using both levels of UV tanning is beneficial because it stimulates melanin production and promotes bronzing. This process occurs when the skin is exposed to UV radiation, which stimulates melanocytes—cells responsible for producing melanin, the pigment that gives skin its color.

By utilizing both UVA and UVB rays, the tanning process can be more effective. UVA rays primarily lead to immediate tanning and contribute to deeper skin penetration, while UVB rays are responsible for stimulating the production of melanin and providing the darker, more lasting tan. The combination of both aids in achieving a more uniform and robust bronzed appearance, enhancing the natural glow of the skin.

While the other options present valid points regarding skin care and tanning, they do not directly relate to the primary benefit derived specifically from using both levels of UV tanning in conjunction.
