Two products that may be classified as suntan lotion are sunscreen and indoor tanning creams. These products serve different purposes. Sunscreen, which may be referred to as sunblock, protects skin from harmful UV radiation of the sun. Indoor creams aid in tanning techniques.[youtube:5ylwogv2gAw?version=3;[Sun Laboratories Tanners];http://www.youtube.com/watch?v=5ylwogv2gAw?version=3&feature=related]
L-Tyrosine and melanin are ingredients commonly found in these tanning creams. Other common ingredients: various oils, copper and tea extracts. Some products add other ingredients that can bronze or moisturize skin. These products are made for indoor use only. They should not be used while outside because they do not include ingredients for sun protection.
The creams may work in one of two ways. They may increase the melanin production or the blood circulating to the skin. Either way, the melanin of the skin is increased. Typically these creams are used with a tanning machine that gives off UV light.[I:http://cosmoread.com/wp-content/uploads/HaywoodHunter1.jpg]
The product that can be used outside is known as sunscreen. This formula, which is used to absorb or reflect ultraviolet rays from the sun, can come in many forms, including gel, cream and spray. Sunscreen can also prevent sunburn from prolonged sun exposure.
Generally sunscreen can be categorized as physical or chemical. Most products include inorganic or organic particulates, or chemical compounds. Physical sunblocks are made to reflect sunlight. Chemical sunblocks are made for UV ray absorption. Because this product can prevent sunburn and skin cancer caused by sun exposure, it is suggested that individuals with all skin types use some form of this product.
Indoor tanning lotions and sunscreen may fall under the category suntan lotion. Both, though used differently, are topical products used on skin. Sunscreen blocks the skin from radiation. Indoor tanning lotions improve tanning methods, they may also bronze and moisturize.
