No. Tanning beds use UVA rays. They may not only inflict the same type of skin and eye damage as the sun, but may also be as much as 12 times stronger than natural sunlight. Although UVA rays are milder than UVB rays—the main cause of sunburn and sun cancer—UVA wavelengths are longer and they penetrate deeper through the skin's layers. UVA rays contribute to wrinkling the skin, as well as to the development of skin cancer.
