Final answer:
Indoor tanning sessions should be spaced at least 24-48 hours apart, but UV exposure from tanning beds can still cause skin damage and increase the risk of skin cancer.
Step-by-step explanation:
Regardless of a client's skin type, indoor tanning sessions at a salon should be no more frequent than 24-48 hours between visits. Tanning, whether outdoor or through indoor tanning beds, exposes the skin to ultraviolet (UV) radiation. While tanning beds may use UV wavelengths considered 'safer', they still pose a risk of skin damage and the potential for skin cancer with prolonged exposure.
The body's defense mechanism against UV radiation is to produce melanin; however, it takes about 10 days after initial exposure for melanin synthesis to peak. Furthermore, excessive exposure to UV radiation, whether it's from the sun or tanning beds, is a leading cause of skin cancer, and repeated exposure can significantly increase skin cancer risk.
