Philadelphia City Council voted unanimously on Thursday to require that minors - those under 18 - be accompanied by a parent each time they go indoor tanning.
The bill also prevents those 13 and under from using commercial tanning beds without a doctor's permission and will make facility owners present each customer with a list of health risks.
At Thursday's City Council meeting, only two people spoke on the bill, one attacking it as too weak while another said it was too strong.
Kelly Andrews, a Health Initiatives Representative from the American Cancer Society, spoke in opposition, saying the law should go further and prevent all minors from indoor tanning.
"Minors. . .are especially at risk for the damage associated with exposure to ultraviolet radiation. . .because their skin cells are dividing and changing more rapidly than those of adults," she said.
Andrews noted that skin cancer ranks as the second most common cancer in Americans aged 15-29 behind Lymphomas.
Also opposed was Joseph Levy, Senior Vice President of the Smart Tan Educational Institute, a lobbying and credentialing group for salons. He said he would have supported the law if it required parents to accompany minors only on their first trip to the tanning salon.
Levy believes Greenlee's law will drive teens to tan more aggressively outdoors or use home units.
Valerie LaVigna, owner of five Hollywood Tans in the Philadelphia area, thinks the law will not only hurt her business - she estimated 20 percent of her clients are minors - but that it will also place a burden on parents, especially those whose children tan as a low-cost way to treat skin disorders, like psoriasis and eczema.
"I'm not an expert on this," Greenlee responded, "but I. . . think the vast majority of her customers are there for cosmetic reasons, not for medical reasons."
Greenlee was surprised to hear opposition because no one showed up to the bill's earlier hearing.
The law will become effective 60 days after Mayor Michael Nutter signs it. Nutter has supported the bill.
State Rep. Frank Farry (R, Bucks) has introduced a bill in Harrisburg that would prohibit those under 17 from indoor tanning in Pennsylvania. That bill is awaiting action in the state legislature.
When asked if he would support a state law, which would preempt the city law, Greenlee responded, "I would not be against it but I thought we would take a. . . more moderate approach."
