Gov. Haley Barbour has signed a bill that would require anyone 17 or younger to get written permission from a parent or guardian before using an indoor tanning facility.

The bill also would require a parent or guardian to remain at the gym, salon or other facility when someone 13 or younger uses a tanning bed.

The parental permission would be valid for a year and can be revoked at any time.

The law takes effect July 1.

The bill is House Bill 214.
