. Increasing blood flow to the skin is a proposed mechanism, which may in turn stimulate production of melanin by melanocytes. Indoor tanning lotions usually contain 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 lotions are usually designed to only use ingredients that will not cause damage or build up on acrylic surfaces. This is because all tanning beds use 100% acrylic in their protective shields. This is one reason people should not use outdoor tanning lotion in a tanning bed, as some common ingredients such as

Bronzers

Some lotions have a bronzing effect to them. There are three different types of bronzers; cosmetic, natural and DHA. DHA (dihydroxyacetone) is a higher level of bronzer that stays on the skin for about 4–5 days depending on how much one exfoliates. Natural bronzers that are made from plant extracts, and stay on the skin for about 3–4 days, also exist. Cosmetic bronzers stain the skin the most, they stay on the skin for about 1–3 days and can be easily washed off in the shower. These bronzers work with the skin to provide a darker cosmetic color. They take approximately 4–6 hours to develop full color. Having a base tan before using a bronzer produces a more natural looking color. Natural bronzers use natural ingredients, such as caramel, riboflavin, etc. These ingredients provide a slight instant boost of color, but will wash off in the shower. Higher quality natural bronzer lotions will have certain organic ingredients/natural or exotic extracts that aid in the process of tanning (melanin production/oxidization).

Moisturizing

One of the primary purposes for using indoor tanning lotions is to moisturize the skin. This is because tanning (indoors or out) can dehydrate the skin so additional moisturization is needed to compensate and leave the skin looking smooth and healthy. One of the most popular moisturizing elements in tanning lotions is

Outdoor use

Most indoor tanning lotions do not offer protection from the sun (have no SPF) and are not intended for outdoor use. However, many tanning lotions now contain SPF.
