Despite being classified as a Group 1 carcinogen by the World Health Organisation, sunbeds are used by approximately 6 million people in the UK, with almost half of them being 18-34-year-olds. The industry is governed mainly by the Sunbeds (Regulation) Act 2010, which prohibits use by under-18s and, in conjunction with other regulation, sets a maximum UV output equivalent to the midday Mediterranean sun.
