What is the UVB percentage in a Level 4 tanning bed?

In a Level 4 tanning bed, the UVB percentage is commonly around 3%. This level of tanning bed is designed to provide a balanced exposure to both UVA and UVB rays, facilitating a deeper tan while also allowing for adequate skin protection.

The UVB rays are primarily responsible for producing a tan, as they stimulate melanin production in the skin. A 3% UVB output is effective in promoting tanning without excessively increasing the risk of skin damage associated with higher UVB levels. Understanding the specific percentages helps tanning professionals manage clients' exposure effectively, ensuring a safe and satisfying tanning experience.

Other percentages provided in the options either represent levels too low, such as 2%, which may not achieve the desired tanning results, or values that are excessively high, such as 5% or 10%, which could increase the risk of skin damage and should be avoided in a typical tanning bed designed for a Level 4 experience.
