Tanning businesses provide services intended to give the skin a bronzed appearance. Many operate sunbeds, which use ultraviolet (UV) lamps, while others offer spray tans or apply tanning products without UV exposure. Customers may be able to choose from different application methods, shades and levels of coverage, with staff explaining how a session or treatment works and what preparation is needed. Sunbed sessions usually involve a timed period on a tanning bed or stand-up unit, with protective eyewear provided or required. In the UK, businesses must not allow anyone under 18 to use a sunbed. Spray tanning typically involves applying a fine mist of tanning solution by hand or in a booth; customers may be advised on exfoliation, clothing and aftercare to help the colour develop evenly. Some salons also sell self-tanning lotions, mousses and related skincare products. UV tanning carries health risks, so customers may be given safety information before use.
