any people use tanning beds as a form of tanning. These people believe it is the best way to get a natural-looking tan without going outside and sitting in the sun for hours. Tanning beds produce a natural-looking tan that lasts as long as a regular tan. Although this is true, there are many downsides to using them, as well. One downside to using them is that just one session in a bed can increase the risk of developing skin cancer. Tanning beds can also make your skin age quicker, become addictive, and cause burns when used too often.
