Indoor Tanning Lotion
Indoor tanning lotions accelerate the sun tanning, tanning process, by promoting the production of melanin. Increasing blood flow to the skin is a proposed mechanism, which may in turn stimulate production of melanin by melanocytes. Historically, indoor tanning lotions have contained no sunscreen and offer no protection from the sun. However, many tanning lotions currently contain sunscreen. Unlike sunless tanning lotions, these are designed for use with an ultraviolet source such as a Indoor tanning, tanning bed or booth. Ingredients Some of the active ingredients found in common tanning lotions include melanin and L-Tyrosine. Other commonly found ingredients include tea oil, copper (in many different chemical compounds), green tea extract and many other natural oils.

In women, melanomas most commonly occur on the legs; while in men, on the back. Melanoma is frequently referred to as malignant melanoma.
