Tanning composition

Patent Granted Indoor tanning lotions accelerate the 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.[1][verification needed] Indoor tanning lotions contain no sunscreen and offer no protection from the sun. Unlike sunless tanning lotions, these are designed for use with an ultraviolet source such as a tanning bed or booth.
