The process where skin pigmentation is darkened due to exposure to the ultraviolet light rays is known as “Tanning”. The tanning process of skin is generally of two types. One is immediate tanning and the other is delayed tanning. The immediate tanning is caused by the Ultraviolet A (UVA) radiation of sunlight which appears just a short time after the sunbathing and usually lasts only a few hours or days. The delayed tanning is the response to the Ultraviolet B (UVB) radiation of sunlight and usually appears 2-3 days after the sunbathing and lasts longer with the natural renewal of skin. The intensity of the tanning varies as it depends upon the type of skin.
Indoor Tanning Process and Devices
Indoor tanning has become very popular and just like regular tanning should include indoor tanning lotion. A clamshell like tanning bed is used as the tanning salon equipment in most of the tanning bed salons. Customers have to lie down on a plexiglass surface where the tanning bed lamps from above and below reach the customers body. The latest high tech tanning beds are called stand up tanning beds and don’t require a person to lay down on plexiglass.
