Researchers surveyed operators at 243 indoor tanning facilities in Missouri and found that almost two-thirds said they accept customers as young as 10 or 12 years old, sometimes without parental consent. Workers at 43% of the businesses said there were no health risks linked to indoor tanning, and almost twice as many said tanning provided protection against sunburns. A bill in the Missouri Legislature would require parental consent for anyone under 17 to use an indoor facility's tanning device.
