Tanning Bed Lotion Information
Unlike sunscreen or what is commonly called suntan lotion, indoor tanning lotion is designed to amplify the effects of ultraviolet rather than block them. This is usually accomplished by using ingredients that promote the production of melanin (including using actual melanin as an ingredient) or by increasing the blood flow to the skin, thereby increasing the amount of melanin that is brought to the top layers of the skin. Indoor tanning lotions contain no sunscreen and offer no protection from the sun.
Tingle is the de facto standard description for indoor tanning lotions that contain ingredients that increase blood flow at the skin level. This is because the ingredients cause the wearer to experience a tingling sensation (of varying degree). The science behind the concept is more theory than proof, but it is usually accomplished using irritants or chemicals that cause a reddening sensation, flushing the user's skin.
People react differently to the ingredients, and one lotion that has no tingle effect on one person may cause mild pain in another. This is why it is impossible to create a system of rating tingle that is objective. Some companies do offer ratings that offer some guidance to the consumer, but it is not standardized. Most companies produce lotions with and without ingredients that tingle, as many do not prefer this method of tan enhancement or find it uncomfortable.
