Indoor tanning lotion

[1] Increasing blood flow to the skin is a proposed mechanism, which may in turn stimulate production of melanin by melanocytes.

Indoor tanning lotions are usually designed to only use ingredients that will not cause damage or build up on acrylic surfaces.

This is one reason people should not use outdoor tanning lotion in a tanning bed, as some common ingredients such as mineral oil (common ingredient in cosmetics, including some baby oil brands) will damage the surface of the acrylics.

DHA (dihydroxyacetone) is a higher level of bronzer that stays on the skin for about 4–5 days depending on how much one exfoliates.

Higher quality natural bronzer lotions will have certain organic ingredients/natural or exotic extracts that aid in the process of tanning (melanin production/oxidization).
