WHen tanning in a uv bed do you have to use tanning lotion?

You don't necessarily have to use a tanning lotion, however many will highly recommend it. Tanning lotions help you to get a darker color faster, plus if you go in a tanning bed with dry skin, 60% of the rays are bouncing off of you, so that's money wasted. On top of that tanning lotions have a lot of vitamins and minerals that help prevent fine lines and wrinkles.
