What about use in moderation? Intentional UV exposure is unsafe, period, even if you only do it every once in a while. In fact, using a tanning bed even one time before age 35 raises your risk of developing melanoma by a stunning 75% — and that risk goes up every time you do it.

While often associated with good health, the “glow” of a tan is the very opposite of healthy; it is evidence of DNA injury to your skin. Tanning damages your skin cells and speeds up visible signs of aging. Worst of all, tanning can lead to skin cancer. It's a fact: There is no such thing as a safe or healthy tan.

Wearing sunscreen in a tanning bed prevents you from getting the bronze tan you are after. It also fails to protect your skin as it is only effective against natural UV rays. Tanning beds are not recommended because research repeatedly shows they are not safe. They can cause premature aging and skin cancer.

Because your skin is constantly creating new skin cells on the epidermis level, any skin treatment will fade over time. Spray tans generally last for 7-10 days, depending on the coverage you requested; if you wanted a lighter color, your tan could fade more quickly.
