What waves do you use in sun tanning beds?

Sun tanning beds primarily use ultraviolet (UV) radiation, specifically UVA and UVB waves. UVA rays penetrate the skin more deeply and are responsible for skin aging and tanning, while UVB rays are more intense and contribute to sunburn and the skin's production of vitamin D. Tanning beds typically emit a higher proportion of UVA rays to produce a tan more quickly, but this also increases the risk of skin damage and cancer. It’s important to use tanning beds cautiously and consider the associated health risks.
